"you're so sensitive after a workout, aren't you?" he purred, reaching around them to rub their nipples as he pressed against their back.

they were still in a trance, and their muscles felt weak. they didn't have any desire to resist, but they felt like they couldn't, even if they wanted to.

and their chest did feel sensitive. it felt like the blood that was pumping through their body was going everywhere except their brain, especially to their chest and genitals. like it was making them become swollen and needy.

their arms trembled as they held themself up above the bed, until he put a little more of his weight on their back, murmuring for them to relax, and they just melted into it, their arms dropping, their stomach and chest collapsing onto the mattress.

"that's it," he said, his voice droning in a hypnotic tone. "this is just part of your post-workout routine, shark... after all... you'll be more motivated... if you're rewarded for it. it will feel better... knowing that your workout is not only changing your body and making it stronger, in the long term... but that it's preparing your body to relax, let go, and be penetrated... in the short term."

they could feel his hard cock pressing against them, even with both of their underwear between them.

"besides," he continued, "that same testosterone that makes it easy for you to gain all of this muscle... can cause atrophy... so it's important to keep the blood flowing... deep inside of you... and to stretch you out frequently. you're already working out three times a week... it should help... if i just push deep inside of you... after every workout..."

he slid down their underwear, pulling out his cock, and rubbing against their wet entrance.

"it's so easy to relax now, isn't it? your body needs to relax... every muscle is exhausted..."

they could feel how easily he pushed inside of them. how they were completely open.

the inside of their body was so sensitive, too, even though they were just letting him in, completely unable to even clench around him. every thrust felt so satisfying, they could feel every movement against their walls. they could feel how he was stretching them, filling them. how deep he was going. and they could hear how wet they were.

"it felt so good, didn't it?" he purred, thrusting inside of them at an even pace, using just enough force that they could feel it, but still saving enough energy to talk. "it felt so good, being in a deep trance as you moved your body... as you pushed yourself... as you put all of that tension on your muscles... and you did such a good job, maintaining your form... you were so obedient... and you can feel how well you did, can't you? you can feel how well you used your muscles... you can feel the exact muscles you were targeting... it feels nice, doesn't it? that weak feeling..."

it really did feel good. they loved every moment of it. the workout itself almost felt like getting fucked, really, when they were straining and panting and they kept being pushed even when they felt like they couldn't take much more.

"it's sort of ironic, isn't it? how you're becoming stronger, but it still makes you so weak... how the more you push yourself, the more your muscles grow and bulge... and yet, you feel so tired and helpless afterward... how you become more masculine... and yet, you become so easy to dominate and penetrate..."

one of his hands continued touching their chest, while the other moved to their t-dick, holding it between two fingers and squeezing it with every thrust.

their mouth was open, their tongue out slightly, moans slipping out without any thought. it felt so good, it was unbelievable. it was hard to do anything except take it.

"you get so hard, but you also get so wet..."

they were already getting close. he felt so big inside of them. they could feel his cock throbbing.

"and your mind gets so open, too, doesn't it?" he murmured, his own breath getting heavier. "every part of you is so open... so weak... so vulnerable... ready to accept whatever i give you... isn't that right?"

they could only respond with a moan. now, on top of the nipple stimulation, and their t-dick being touched, and the vaginal penetration, they could feel his words penetrating their mind. it only turned them on more, overwhelming their body.

"that's right," he said breathily, his movements becoming just a little less even. "that's good... complete relaxation... complete surrender... just stay nice and open for me... the way you should always be, after a workout..."

his thrusts were getting harder, more forceful, but their body took it so easily. they felt nothing but pleasure.

"you're going to cum already, aren't you?" he whispered, pressing deep inside of them. "you can't help it..."

it didn't even feel like an actual command, but they were already on the edge, and it pushed them into an orgasm before they could even think about it, their body just completely succumbing to the pleasure, twitching and shuddering and pulsing on its own, as their mind went numb.

"good, good," he whispered, continuing to thrust deep inside of them and touch their sensitive t-dick, "such a good boy..."

it was already too much, but the feeling of his cum being pumped into their body made them cum again, the weak, helpless sensation making everything so sensitive, making them completely lose control of their orgasms, making them feel like their body was completely his.

he stayed inside of them for a moment, softly stroking their arm, cooing praise at them and directing them to stay calm and relaxed. if he hadn't done that, the overstimulation really might have gotten unpleasant, but everything felt alright when he was reassuring them, and they were able to slowly come down from their orgasm.

"in a moment, let's get you your protein shake," he murmured, "and then we can take a shower, and give you a nice massage..."

"that sounds good," they whispered, realizing they hadn't even said anything this entire time.

"of course it does," he droned. "you always want to follow along with what i tell you to do, don't you?"

they knew it would have sounded good to them anyway, but their mind buckled at even the slightest dominance from him, and they found themself feeling weak and fuzzy again. even during the aftercare, he was asserting his control... he was serious about it.

a smile spread across their face, and they shuddered again. it felt good.
