Three weeks later

Alice woke up very late, but Jake was still asleep. The first thing she felt was shame, as usual. It's been going on like this for over three weeks now. She wanted to come over for a quickie, like he promised, but as always, it turned into an all-nighter.

As she quietly stood up from the bed, her ass and pussy felt sore from all the fucking. Her clothes were spread over the floor. She had several outfits at his place by now, and sometimes he made her change four or five times in one evening. Jake had developed quite the costume fetish, and of course, he made sure he always got some good pictures of her in them, too.

Alice felt a pit in her stomach when she thought about that. She trusted Jake, but it was frightening to know how much leverage he had over her with this. He must have accumulated hundreds of condemning pictures and videos of her by now. Cleaning his dishes in a bunny outfit. Sucking his cock in a devil costume. Getting fucked in the ass, dressed as a cheerleader. Mopping his floor, dressed as a French maid. He even made her go grocery shopping for him in that maid costume once. Oh, the looks she got... She never felt more ashamed in her life. And yet, when she came back to him, she was soaking wet, begging for more.

Alice quickly grabbed some fresh lingerie out of her old/new drawer and put it on. There was no regular clothing here for her anymore. She looked at Jake, who was still sleeping, before she left the room. He looked innocent, but he wasn't. He had turned into the meanest guy she ever met, but she kind of loved him for that. Alice had given up trying to make sense of her feelings. After she came to his place three weeks ago, she promised herself it was the last time, but the sex was so incredible, that she couldn't live without it anymore. It was not just the sex, though. The way he treated her... Like trash. Like pure garbage. She loved it. It was as if something had awakened in her. She actually was a cheating whore! Jake had woken up by the time Alice came back from the bathroom. He greeted her with a sly smile.

"Morning, slut." 

"Good morning, Jake," Alice replied meekly. "Do you need anything from me before I go?"

Jake checked the clock. "You got a date?"

Alice nodded, avoiding his eyes. "I have to be at the tennis court in two hours and I need to get changed at home before that."

"I see..." Jake lifted the blanket. He got out of bed, completely naked. Alice liked her lips intuitively at the sight of his beautiful cock. "Get down on your knees. A good sport needs a good breakfast."

Alice was not happy about running late again, but complaining would only make things worse. She got down on her knees right in front of him and looked up into his eyes, offering him a submissive gaze, and he put his right hand on her cheek

Softly, she asked, "How would you like me to suck your cock, Jake?"

"Slow and deep, slut.”

He flashed her a satisfied smile after he spoke. She started off by taking his cock as deep in her mouth as she could and slowly sucked him off. Sucking his cock was basically routine by now. She didn't get any 'real' pleasure out of it, but she loved the way he dominated her. As expected slow and deep was just a warm-up. By the time he ejaculated, he was roughly fucking her face, pulling her hair. Luckily, he came fairly fast and Alice swallowed the entire load without any spillover, which granted her a "Good girl" and a pat on the head.

After that she left quite quickly, drove home, took a shower, packed her bag, and grabbed her tennis racket. Luckily Jake didn't seem to mind her still having a boyfriend. It was like she was living two lives now. Her secret sex life was with Jake and her normal life with Mike. She still had sex with Mike though, but it was mostly to keep him in the dark. She enjoyed it less and less, and she had to fake orgasms every time. The big problem was that she was still somewhat horny after sex with Mike. And that eventually ended up in sex with Jake. As soon as she had the time, Jake was there and ready to provide.

Alice arrived just in time and saw Mike sitting in the lobby. He greeted her with his charming smile and a kiss. She felt like a piece of shit. He was just perfect and did so not deserve a whore like her to be his girlfriend. Why was she even still with him? She knew she was selfish. If she could only get rid of this Jake thing. The things he made her do… 'Why is this even happening?', she wondered for the 100th time.

"You are not late!" He sounded happily surprised.

"What is my reward?" Alice asked playfully and reached out her hands as if expecting a present.

"Well…" he started, "I got a very nice surprise for you, but you can only have it, if we win today."

Alice rolled her eyes, "You guys are way too competitive, did anyone ever tell you this?"

Mike laughed and shrugged, "That's true, but I see it as a compliment. By the way, you should get going. Mum and Melissa are already in the dressing room."

"Right," Alice said with a nod. "See you on the field."

She gave him a playful bump on the head with the net of her racket and went to the dressing room.

In there she found Melissa and her mother Angelica. Ann was already dressed in a white tank-top and skirt. She looked amazing for her age. Alice could not help but adore this lady's beauty every time she saw her, but she still paled in comparison to her daughter. Melissa's dark blue skirt was a bit shorter than her mum's and it looked like she just closed her sports bra of the same color Alice entered. If she would have just been here a minute earlier, Alice caught herself thinking with regret.

"Hey!" Melissa shouted out happily as she came running to Alice, greeting her with a tight hug. Alice felt overwhelmed for a second, but quickly dropped her bag and wrapped her arms around her close friend, embracing the warm feeling Melissa gave her. Her hair smelled nice.

"Hey!" Alice breathed in Melissa's ear, forgetting herself for a moment. Melissa's breasts pressed against her own, and Alice felt an arousing sensation. She had to snap out of this before it was too late.

She freed herself from the hug, just as Ann said, "You two act like you haven't seen each other in ages. Come on girls, get dressed!"

Alice grabbed her bag again and found an empty locker she could use. Angelica seemed a bit colder towards Alice lately. Maybe it was just her imagination though. Alice put her bag down and started to undress.

"You want to wear just that?" Alice heard Ann say. She looked up and saw Melissa still wearing the dark-blue skirt and sports bra, just now with a white fishnet mesh shirt over it.

"Oh, mum, don't be a prude." Melissa said, rolling her eyes.  "This is totally fine to wear and it's not like anybody is gonna see me in this besides you guys and Mike. So whatever, right? Alice, back me up!"

Alice didn't want to get in the middle of this but she certainly liked how Melissa looked. "It looks really good on you," she said, and Melissa's beautiful grateful smile made Alice blush.

"Well," Ann said, clearly not happy, "Let's go then. Hurry up Alice, we see you there."

They left her alone and Alice quickly changed into her tennis outfit which was very similar to Angelica's, but in red. Alice knew that Melissa liked her in red. That was the other thing in her life that was not so normal anymore. Ever since the day Melissa helped her with the boxes at Jake's place, Alice found herself weirdly attracted to her. Nothing had happened between them since that kiss during their shopping session, but the sexual tension was still undeniable.

Aside from that, Melissa was turning out to be a really great friend, and Alice liked her quite a lot. Which was another reason not to fuck things up with Mike. At first, he was delighted that Melissa liked Alice. Apparently, this was the first time ever, that Melissa approved of Mike's girlfriend. Alas, Alice and Melissa became such good friends, that they started to spend more time together than Alice did with Mike. She needed to be careful with that going forward.

Just when she was about to put her phone in the bag she saw a message from Jake: "BTW you're playing without panties today. Send me a pic of your pussy or you will be punished."

Alice thought 'fuck' and quickly pulled her panties down. Jake's punishment was not something to look forward to. She went to the mirror, lifted her skirt up front, revealing her shaved pussy, and took the picture. She sent it to Jake without any comment. Alice knew she could technically just put her panties back on now, but it felt so much better to obey Jake. It gave her a weirdly thrilling feeling doing something so stupid and slutty for him. She entered the court and felt quite breezy downstairs. Okay, maybe this was a bit too stupid and slutty after all, but there was no going back now.

Alice felt destroyed towards the end. Mike pulled most of the weighed for the both of them. Alice was once again amazed at what shape this family was in. Sure, they were sweating, just like her, but they never ran out of breath. And it looked like they could go on forever. If only their dad was here, Alice thought. Last week she came here, just to watch all four of them play, and cheer Mike on. Merely watching this attractive family doing sports was something she could do all day. To her own surprise, Alice had caught herself mostly drooling over Melissa and Angelica, instead of Mike and Gio. There was just something about them...

Melissa was hands down the most beautiful young woman she ever laid eyes on, and since she looked so much like her mum, Alice found herself wondering about Angelica too. Just yesterday she was imagining having sex with both of them. Mother, daughter, and Alice in the middle. She wasn't into women, never has been. But it seemed impossible not to be attracted to Melissa and her mum. Alice got extremely horny imagining exploring their toned bodies. Most of all Melissa's breasts. She fantasized about sucking on them way more than she'd like to admit. Of course, that only landed her right at Jake's doorstep, in the end.

"Focus, Alice!" Mike brought her back into the present. They were losing. Alice did not want to lose her face and used whatever energy reserves there were left. It was a match-point for Ann and Melissa.

Alice jumped backwards to get the ball and fell down on her butt. The ball flew in Ann's direction. It happened so fast and yet Alice saw it all in slow motion. Ann made a step to get the ball, her gaze shifting suddenly to Alice. A shocked expression on her face. Then she fell, screaming in pain. Alice realized her genitals were completely on display. Melissa had the same shocked expression on her face as her mother. Alice got up quickly. Did Mike see her like this too? How could she only be so stupid?!

"Mum!" Mike screamed and ran to her. He helped her up, but she couldn't stand.

"I think I broke my foot." She cried. He supported her with ease.

"I'll take you to the hospital. Sorry, Alice. I hope you don't mind?"

"No, no of course," Alice mumbled, "Call me later, okay?"

It seemed like he didn't see what his mum did, but Alice was sure she was gonna tell him soon wnough. Mike gave her a peck on the cheek and said goodbye. At that moment Angelica looked at Alice and silently shook her head in disbelief. Alice felt so ashamed.

After Mike had left with Ann, Alice and Melissa went to the dressing room together in silence. When they were in Melissa turned to Alice.

"Soooo…" Melissa started, "Did you forget to wear them or what was the idea?"

"I-I don't know." Alice shook her head. "I thought… I don't know what I thought. This is so embarrassing!"

"Certainly a creative technique," Melissa scoffed. "I just wished your distractions wouldn't hurt anybody."

Alice looked at the floor. She couldn't stop the tears anymore. Suddenly she was crying like a river. To her surprise, Melissa came closer, putting a tissue in Alice's hand. Then Melissa was hugging her in a very soothing way. Alice just let it out, while Melissa caressed her hair, whispering "Shhhh" in her ear.

"It's okay, Alice. Nothing is going to change. It's not so bad."

She was such a good friend. Alice wiped off her tears and dropped the tissue on the floor, now enjoying Melissa's embrace. Alice noticed that something was off. Her hands were on Melissa's back but there was only skin. No fabric. Did Melissa take her bra off before hugging her? But when... why…

Alice pulled back in surprise, seeing Melissa's naked breasts for the first time. In this moment, Alice felt dizzy, as if someone had hit her over the head. She felt drawn to Melissa. All this time she wondered about Melissa's breasts and tried to imagine them. But what she saw now was even better than her fantasy. Melissa was a goddess with enchanting wonderful breasts. Alice felt herself leaning in closer again. Melissa's gaze was either serious or curious. Her lips were so close. And they came closer ever so slowly. Melissa delicately wrapped her arms around Alice again, while their tongues met. They stood there for a while just kissing slowly. Then Alice felt Melissa's hand moving down her skirt, finding her bare ass.

"You did that for me, didn't you?"

Alice could not tell her the truth, but she also didn't want to lie so she just didn't say anything. Instead, she started feeling up Melissa's tits. They felt so wonderful in her hands.

"Why am I so attracted to you, Alice?" Melissa went on, "I don't understand…"

"Me neither," Alice moaned, "I don't know what I'm doing."

But instead of stopping their make-out session just got more intense. Melissa undressed Alice, and Alice let it happen.

Melissa proposed, "Let's hit the showers."

Alice could still not believe what she was doing. This was her boyfriend's sister! How was that happening? Melissa seemed to be just as clueless as Alice was. All they knew was, that they wanted each other. Alice closed her eyes and tried to collect her thoughts.

"Melissa… this is a bad idea." She took a step back and tried to calm her body, which was aching for more.

"I know, Alice," said Melissa's soft voice. "Maybe it's better if we go separately. You can go first."

Alice opened her eyes and saw Melissa standing in front of her. She still wore panties and covered her boobs with one arm. Alice turned around quickly before she got the wrong idea again. She grabbed her towel and fled to the showers.

Alice stood under cold water, trying to calm down. What a mess of a day. And her mind was still full of lust. She wanted to make out with Melissa. She wanted to fuck Jake. She wanted to hug Mike. Would she ever feel normal again? Alice closed her eyes and tried to locate the point when everything turned upside down. It must have been the first time she went to Jake last month after his vacation. It was the first time she had sex with him since they broke up. The first time she cheated on Mike. And there was something odd about that day… 'My Bra', she remembered! It was like an epiphany. How could she forget? First, she was sure she had forgotten to put it on at Mike's place, but she evidently didn't. Jake confirmed that she left it at his place when she slept with him for the second time. And she knew for sure that she did not wear a bra before they had sex! Did she take it off before she went to sleep because of her headache? No, she didn't remember that. She didn't even really remember going to sleep. But she knew she did. Her mind got foggy thinking about it. What did any of that even mean? Was there even a connection? Something was definitely off since that day. She had to figure this out. Maybe there were more clues. Alice felt a little ray of hope for her head, some sort of warmth. No, wait… that was the water.

Alice opened her eyes and gasped in shock. Melissa stood right next to her, her hand on the water handle.

"I'm sorry, but I could not resist."

She was smiling and completely naked. Alice's mind shut down at the sight. Instantly they embraced each other, kissing and rubbing their naked bodies together under the hot shower. She had to fuck Melissa. It was all she wanted. All she could think of. Alice felt Melissa's tits pressing against hers and it was heaven. They eagerly kissed each other, even more passionate than before. She wanted to please Melissa. Wanted to explore every inch of her with her tongue. She started at the neck, liking her way down to Melissa's majestic boobs, the warm water raining down on them.

"Oh, Alice. That feels so good!" Melissa moaned from above, caressing Alice's wet hair. Alice sucked on Melissa's nipple while groping the other one with her hand. She felt like an animal and she relished that feeling, relished Melissa's tits. "Get on your knees, Alice. I want you to eat my cunt!"

Alice wondered for a split second about the tone, but as she went down on her knees, seeing Melissa's clean-shaven pussy it was all forgotten. Alice never thought she could ever find a vagina attractive, but Melissa's was just divine. And that wonderful smell! 'Oh my god', was all she could think before l burying her face in Melissa's pussy, liking away. Alice looked up at Melissa, who in return looked down at Alice. Melissa was smiling.

"I love that view. Oh god Alice, it's so good! Keep going. Oh yeah! Oh god, you're such a slut!"

Alice didn't mind. She had no mind. She wanted to suck and please. That was all there was. Melissa backed off and leaned against the wall.

"Come on, I just needed a little bit of support." Melissa sounded breathless. "Finish me off, Alice. I want you to make me cum."

"I love to make you cum." Alice said mechanically, as she crawled towards Melissa. She felt weird saying it, like a deja-vu, but her mind was too far away to make sense of that. Her mouth was already deep in Melissa's pussy. Her face was drenched by her juices. Melissa soon started moaning very loudly, her legs twitching and her pussy clenching as she came.

Alice sucked on her clit and just kept going until she felt Melissa pushing her back.

"That's too much. Alice, stop!" Melissa knelt down, coming close to Alice's face. "That was amazing." She whispered and gave Alice one last deep kiss before breaking it up, "but I think we should go now." Melissa grabbed her towel. "See you in the lobby."

And with that, she was gone. Alice was still kneeling on the floor, the taste of Melissa's juice on her tongue. She closed her eyes and just savored it.

Alice drove Melissa home, since Mike left in their car to get Ann to the hospital. The first few minutes were sort of an awkward silence. Alice knew they had to talk about it, but she didn't even know where to start. Melissa finally broke the silence.

"Can we agree not to tell Mike about what happened?"

"Are you kidding?" Alice looked at her in shock. "He can never know!"

"Glad we're on the same page there." Melissa sighed. She hid her face in her hands. "I really don't know what got into me."

Alice was relieved to hear that. "Me neither. I am not into girls, you know?"

"Me neither!" Melissa shouted, "I have no idea what's going on, but you just make me so…"

"…curious?" Alice finished, since Melissa was at a loss for words.

"Yes! I am so sorry, Alice. I don't want to come between you and Mike or anything like that."

"Hey, it's not your fault. I feel horrible about this." Alice shook her head. "I want to be a good girlfriend for him and I really love him, you know? But when I look at you…"

Alice shrugged. Then there was silence again. She parked in front of Melissa's family home. Alice decided that she needed to know more.

"Can I ask you something?"

"Sure, Alice."

"Since when exactly do you feel that way about me?"

"How is that important?"

"Just a hunch. So?"

"Well… to be honest since I first laid eyes on you. When Mike brought you to dinner."

"Huh… Okay."

"Why? When did you…? You know?"

"Well if I think about it, right after we were getting my last boxes from Jake's place."

"Uh huh… So what?"

"Nothing… Just… I don't know. I have a weird feeling about a lot of things lately. Doesn't matter."

Alice felt torn. She wanted to talk about everything with Melissa so bad. The Italian beauty became such a close friend in such a short time, but Alice could never tell her about the affair. She had to talk to Lisa about that. Lisa knew Jake, and usually, she had a good sense when it came to him. Good thing her birthday party was coming up.

"How about we talk more about it tomorrow?" Melissa proposed, "You could sleep over if you want?"

Alice shook her head. "I can't. I'm spending the day with Mike tomorrow. He's already jealous because I spend more time with you than with him. And the day after I gotta go to a friend's birthday party. Plus, to be honest, a sleepover is probably the last thing we should do."

Melissa laughed. Alice loved her smile. "Okay, good point. But I could come with you to this party, right? You could introduce me to your friends and such."

"I think that's not the best idea." Alice admitted awkwardly, "Lisa is already a bit pissed because she feels I neglect her too much. Maybe another time?"

Melissa gave Alice a very serious look and made pouty lips. Damn, those lips. "Come on, Alice pleeease? I need a fun night out. I promise I'll behave. And after the party, everybody goes to their own beds. Please, say yes?"

Alice knew Lisa would freak out, but she could not say no to those hazel eyes. "Okay, you win. I'll pick you up at 8, okay?"

Melissa beamed at her. "Thank you!"

Then she leaned in and gave a small kiss on the lips that Alice returned automatically in surprise.

"See you then." Melissa trilled, still smiling, and left the car.

"Bye…" Alice mumbled confused.

She had some serious thinking to do today. That would be much easier if she wasn't so horny. She took her phone out and texted Jake. 'Got time? I could be there in fifteen minutes.'

It was probably the last thing she should do right now, but she really needed his cock. After that, she could think. The answer came quite quick. 'Can't today. Come by tomorrow morning at 8.'

"Fuck", she cursed, but it could be worse. Then, he sent her a picture of a woman in a full-body leather outfit with a tail and cat ears. 'Be a good kitty and you'll get your milk.'

Alice sighed. Now she had to go shopping. One time she showed up, not wearing what he demanded. She had no time to go shopping then, and was crazy horny. So instead of showing up dressed as a sexy magical fairy with wings and everything, she just wore white stockings and a mesh shirt with nothing underneath. Her tits were basically on full display with full-on whore make-up to make up for the missing outfit. He led her in, spanked her ass until she cried, and made her promise never to disobey again. Then, he sent her back out, leaving her desperately horny unit she got the right costume. She learned her lesson that day for sure.

Alice started the ignition and went shopping for a kinky cat costume. Thinking about it got her quite excited... She could not wait to play kitten for Jake.
