The doorbell rang right on time. This time, when I opened the door, Jake didn't seem as stressed as before, but rather like someone who still felt strange but had already made up his mind. He came in without a word, kicking off his shoes at the threshold.
“Hey,” he said briefly, looking at me out of the corner of his eye. “Are we doing this in the living room like last time?”
“Yes,” I replied calmly, closing the door. “Today we're going to explore flexibility and range of motion. That means some... more dynamic positions.”
Jake sighed but didn't ask any questions. Something inside me trembled when I realized I no longer had to persuade him. Without comment, he began to undress. First his sweatshirt, then his T-shirt, his pants... until finally his boxers slid down his thighs and fell to the floor. He stood before me completely naked, as if it were normal.
This was the signal I had been waiting for. He was beginning to accept my rules.
“I still feel a little like an idiot,” he admitted, running his hand through his hair.
“That's natural,” I said calmly, staying in my tight-fitting boxer shorts. “Every model feels that way at first. Focus on your breathing, I'll take care of the rest.”
He nodded and stepped into the middle of the room. The muscles on his back rippled with every movement, and I pretended to be a cool professional, even though inside I was burning up.
“Start with a few simple squats,” I instructed, picking up my notebook. “Slowly, so I can watch your muscles work.”
Jake did as he was told. His body moved smoothly, perfectly, and I stood right next to him, touching his hips to “correct his posture.”
I could feel his skin getting warmer and warmer, his abdominal muscles tensing.
"Now we'll move on to positions that test your flexibility," I said in a calm, analytical tone. "I want to see how your muscles react at maximum stretch."
Jake snorted nervously but didn't protest. “You know how that sounds? I hope the neighbor doesn't walk in right now.”
“He won't. The door is locked,” I replied coolly. “Stand with your legs apart. Wider. Good. Keep your balance and breathe deeply.”
He did as he was told. His thighs tensed visibly and his buttocks lifted as he slowly leaned forward. My hands rested on his hips, ostensibly to correct his posture. In reality, I allowed myself a second too long to touch him, running my fingers over his smooth, hot skin.
“Do I really have to stand like this? I look like an idiot,” he muttered, avoiding my gaze.
“No,” I replied quietly but firmly. “You look perfect. Your body is responding exactly as it should.”
I wrote something down in my notebook, but my eyes were still on him. I told him to get into a squat position, knees wide, hands on the floor. The nipples on his chest were already clearly hard, his breathing rapid, though he tried to hide it.
“Good. Now get on all fours,” I said calmly. “I want to check the tension in your back muscles.”
He looked at me over his shoulder in disbelief. “Seriously?”
“Trust me. I know what I'm doing.”
When he got into position, I ran my hands down his back, slowly moving lower... all the way to his buttocks. I pretended to be completely serious, as if it were just a normal muscle test. But in my head, I was buzzing with the realization that Jake didn't even notice how far we had already gone.
I stood right behind him as he knelt on all fours. His back was straight, his thighs wide apart, his buttocks tight as a rock. He looked like the perfect test subject... or like someone who had just given me complete control over his body.
“Hips lower,” I said in a calm, scientific tone, placing my hands on his sides. “Yes, good. Now breathe deeply.”
My chest was almost touching his back, and when I leaned over to “check the alignment of his spine,” my lower abdomen in my boxer shorts brushed against his bare butt. Jake visibly shuddered.
“Matt... that's a little weirdly close,” he mumbled, trying not to move.
“It's just science,” I replied calmly, as if nothing had happened. “I need to feel how your muscles work.”
I slid my hands over his hips, holding him tight to keep him in position. I took a step closer. Now his naked body could feel every inch of my crotch. I brushed against his buttocks, slowly, in rhythm with his breathing, as if by accident.
Jake was breathing harder and harder. His shoulders were shaking, and the nipples on his chest were stiff as little buttons.
“Dude... I... I feel weird,” he gasped.
“It's natural,” I said calmly, moving my hands even higher, up to his stomach. “Your body is just responding to the stimulation. Don't fight it.”
I could see his cock throbbing and hardening beneath him, tensing with every breath.
He was on the edge, his body telling me everything I needed to know.
I was calm.
He trembled like someone who no longer knew whether this was an examination… or something else.
His body trembled under my hands like a taut bow. I felt every muscle contraction, every wave of breath, as if I were holding an instrument that played exclusively for me. My hips moved rhythmically, gently rubbing against his bare butt through the thin layer of boxer shorts. From the outside, it looked like I was adjusting his position. In reality, it was pure provocation.
Jake was panting heavily, his hands digging into the mat, his thighs spread wide and tensing more and more.
“Matt... I... something's happening...” he gasped in a trembling voice.
“Breathe,” I whispered in his ear, still calm, as if I were teaching a class. “It's just a physiological reaction. Watch how your body responds. Nothing more.”
I could see his cock throbbing beneath him, stiff, ready to explode. Jake was already on the edge, and I wasn't even touching him directly. I held him tightly by the hips, moving him slightly, until suddenly his whole body stiffened.
“Oh, fuck!” he cried in surprise, his voice echoing off the walls of the apartment.
His hips jerked in a spasmodic movement, and in the next moment, the first stream of hot cum shot out of his hard cock, landing on the mat beneath him with a wet slap. The next ones hit quickly, leaving white marks on the black surface. Jake moaned deeply, his body trembling with each ejaculation.
I stood motionless, still holding his hips, as if I were just observing the course of the experiment.
“Position number five,” I said coolly, reaching for my notebook. “Uncontrolled ejaculation caused by strong muscle stimulation.”
Jake slumped onto the mat, panting heavily, completely embarrassed.
“Matt... I didn't even... touch myself...” he whispered, as if he couldn't believe what had happened.
I closed my notebook and looked at him calmly, confidently. “I know. It was your body reacting. Exactly as I predicted.”
Inside, I smiled triumphantly, knowing that from now on, he would be coming back for more.
