Jessie laughed when she saw the new toy Amanda had been playing up all week. It was so thin! A slender, purple rod.

“I’m not really sure I’m gonna feel much with that,” she teased.

Amanda waggled it between her fingers like it was a pencil. “That’s because you haven’t seen what it does,” she said, grinning. She pressed a button on one end and handed it to Jessie, then opened a new app on her phone.

“Let me guess, it vibrates.”

Amanda shushed her and tapped her phone’s screen. The toy started to vibrate gently, but then it did something weird. Starting from the base where the button was, it began to inflate, growing in girth in a wave until the whole length was thick like a cock. Then it deflated, starting from the tip and ending back at the base. Then it started again.

“Uh… That’s… Interesting? What’s it for?”

Amanda leaned in close, her lips brushing Jessie’s ear, and whispered, “It’s for making you feel like I’m fucking you.”

Jessie shivered, and Amanda stepped back, still grinning. “Basically, you put that in, and every so often throughout the day I’ll have some fun,” she said, waving her phone. “And then come nighttime you’ll be begging for my cock.”

“Begging, huh? I guess we’ll have to see how good it really is.” Jessie handed the toy back, trying to keep her voice steady.

“Indeed. Why don’t you be a good girl and drop your pants so we can get started.”

At the word “drop” Jessie felt her eyes flutter closed, her limbs suddenly heavy, mind fuzzy. What had Mistress said? Right, to pull down her pants. She pulled them down, then opened her eyes to look at her Mistress expectantly.

“Very good. Now bend over the bed for me.”

Jessie leaned over the bed, bracing herself with her arms, bare arse on display for Mistress. She felt a hand caress a cheek and slide lower to her cunt, and Jessie moaned.

“Good girl. You’d like to try our new toy, wouldn’t you?” asked Mistress. She rubbed Jessie’s cunt in pleasurable circles.

Jessie nodded before she had a chance to remember what Mistress was talking about. If Mistress said that she wanted something, it must be true.

Mistress slid something into Jessie, her cunt already wet enough for it to slip in easily. “How does it feel?”

It was difficult to feel anything at all, but Jessie was honest and told that to Mistress, who chuckled. “Well, that’s the idea, at least at first.” She moved away and did something with her phone, then asked, “How about now?”

Jessie felt something stretch, and realized it felt like a cock sliding inside her, deeper and deeper into her cunt. She gasped, the feeling of fullness pushing her arousal higher. But she felt confused; she already had a toy inside, and Mistress wasn’t anywhere near her. Then the cock seemed to pull out slowly, then thrust into her again. Mistress did something on her phone, and the rhythm got faster, and Jessie squirmed, arching her back to press into the sensation. Strangely that didn’t make it go deeper; it just kept moving on its own rhythm.

Mistress laughed. “I thought you’d like that. I bet that this toy makes it feel like I’m fucking you, doesn’t it?”

Jessie whimpered in agreement.

“Say ‘yes, Mistress.’”

“Yes, Mistress, yes,” Jessie gasped.

“Good girl. But it wouldn’t do for you to come so quickly; we’ve got a long day ahead of us.” She tapped her phone and the toy stopped, deflating to its default size. “Why don’t you get dressed?”

Jessie stood and pulled up her pants. She sat on the bed when Amanda patted the covers beside her.

“Tell me, can you still feel it inside you?”

Jessie shook her head.

“Very good. Soon we’re going to get ready for the day and go about our planned activities. But I want you to keep the toy inside you. You can do that for me, right?”

Jessie nodded eagerly. Anything for her Mistress.

“That’s right. Today I want to have some fun with you whenever I please, so this way I’ll be able to turn on the toy and… Well, toy with you.” She smiled. “But there’s one more thing you can do for me; would you like to know what it is?”

“Yes, Mistress, please.”

“I think that you should also forget that you have the toy inside. You’ll remember us talking about it, but of course you won’t remember anything after your drop, will you? So today when the toy fucks you, you won’t know why you’re consumed by thoughts of my cock inside you or why you’re so aroused. Isn’t that right? It will just feel like you can’t help being a slut.”

Jessie nodded happily. She was a slut, so it made sense.

“So it’s settled! Now it’s just time for you to wake up.”

Jessie was finishing up her oatmeal when Amanda looked up from her coffee and asked, “Got any plans for today?”

“I thought I’d go for a ride before I showered, then maybe laze around playing video games. You?”

Amanda frowned at her phone. “Unfortunately some things came up at work, so I’m going to be busy. I’ll probably join you later on the couch with my laptop, but you’ll have to amuse yourself.”

“Hah, I think I can manage that.”

Amanda smiled as if something she’d said was funny, and waved her off to her bike ride.

It was on the way home, mile 8 of the trail near their house, when Jessie started to feel a bit… Off. The seat of her bike was suddenly very noticeable; every vibration moved up into her pelvis, almost as if she had a vibrator inside her.

She came to a stop, but the vibrations continued like an aftereffect. And as she stood grasping the handlebars, suddenly all Jessie could think about was Amanda fucking her, cock deep inside her. It was so vivid that it almost felt like she was straddling Amanda rather than her bike. She gasped as the visions continued and her mind somehow conjured the feelings of being thrust into again and again.

She came quickly, shuddering, holding herself up with her bike. For a moment her mind was blank with residual bliss, but soon Jessie came to her senses and looked around, blushing. What the hell was she doing?

Luckily the trail was quiet at this time on a weekday; it was why Jessie rode it on her days off. No one was to be seen in either direction down the path.

Jessie hopped onto her bike, still red in the face. She had no idea what had come over her, but better to get home quick. And boy did she need a shower.
