She smiled. The sight of the young man, erect, bound and begging, as he hungrily watched her masturbate turned her on. She shook her head no, pulled off her panties and continued to pleasure herself with her fingers. Jerome's breathing began even more ragged as he continued to watch her fingers reach into her wet depths and then circle over her aroused nub. Cecilia writhed a little, both out of enjoyment but also for the visual effect. Her breasts bounced from the movement. Jerome moaned. He wiggled his hips and thrust upwards. The pressure built and he could feel his oncoming orgasm build. He had never come just from watching a woman with no one touching him. He felt his core spasm, but instead of spurts of semen he felt the pressure move through his penis and his erection grow even longer. He gasped, unsure of what just happened but still wildly turned on without any release.
Cecilia moaned at the sight of Jerome's erection growing. It was incredibly hot and the young stud's cock was now undeniably even longer and thicker than before. She would check the readings later to figure out exactly how much growth had occurred.
"Looks like you still need some help with that." She purred. "Don't worry. I won't let you down. Would you like me to fuck you in that hot, tight muscular ass?"
"Gods, yes. Please." Jerome panted.
"Okay." Cecilia said.
She pulled a harness and dildo out of one of the drawers and strapped it on. The dildo was the double kind designed to penetrate both partners at once. She happily inserted the more curved end into herself, enjoying the feel of it inside her. She then walked over to Jerome, who continued to watch her with pleading eyes.
"Here are the rules. We have to be careful to keep all the sensors on you." Cecilia commanded authoritatively. "So when I unstrap you, you will carefully get off the examining table and lean over it, being careful to place your torso in such a way that the sensors stay attached to your body. If any of them come off, I will be very annoyed with you. Is that clear?"
Cecilia had an excellent read of men's desires, given her vast experience. She had Jerome figured as someone who like to be dominated a bit. She wasn't going to push it too far, since she had not discussed things like spanking beforehand, but she figured he would probably get off on her acting authoritative. She was right. Jerome gulped and quietly promised to be very careful with the sensors. His eyes looked eager.
Cecilia undid his straps and the college student carefully slid off the table. He leaned over the table, carefully making sure the wires were out of the way and were unlikely to be accidentally knocked off in their current position. Cecilia put on examining gloves and squirted lube onto her hand. She applied the lube generously to his asshole, caressing the sensitive skin around his rectum with her right hand as she did so. With her left hand, she reached around to cup Jerome's balls and gently tug on them. Her right hand continued its gentle ministrations. She slid one well-lubed finger into his rectum and made a slight come hither motion to massage his prostrate. She slid her left hand up to stroke his shaft. He moaned and thrust into her hand. She continued fingering him with one hand and masturbating his huge cock with the other so that the arousal would relax his asshole so that she could enter him safely.
She removed her hand from his shaft and applied lube to the dildo. She lined the dildo up with the entrance of his rectum and then slowly pushed her way in. He gasped at how full he suddenly felt. Cecilia started thrusting slowly in and out. Each thrust rubbed the sweet spot inside him. He moaned.
Cecilia was also incredibly turned on. Each rocking thrust moved the other end of the dildo inside her, rubbing her g-spot. She moaned, increasing the tempo of her thrusts, and wrapping her hand back around Jerome's thick member. Jerome moved his hips in time to both move against the dildo and thrust his cock into her hand. They developed a rhythm of this, the pace quickening over time.
Jerome felt the pressure in his core build again. He moved his hips back, impaling himself deep against the dildo and then bellowed as he felt what he assumed would finally be his orgasm rip out of him. Only, once again, the pressure that built up moved up his cock and resulted in further growth instead of the energy being released in the form of ejaculation. He moaned in frustration.
"Why can't I come?" he whined, close to tears.
"Don't worry. You've been a good boy. Continue to be a good boy and I will help you come." Cecilia murmured in his ear. She had felt the growth occur under her hand. The young stud's cock was absolutely huge now. She wanted to feel it fill her. She unstrapped the harness and took it off, putting both the harness and the dildo in a nearby tray on the counter.
"I want you to show me what you've got." She commanded, leaning over the examining table herself, jutting her luscious round ass out behind her.
"Ass or pussy?" Jerome asked, coming around behind her.
She considered. "Pussy for now."
Jerome entered her hot, wet pussy, pushing his massive member deep inside her. Cecilia gasped. She loved the feeling of being completely filled that came with these drug-enhanced cocks. She rocked her hips back in time with Jerome's thrusts.
"Touch me like I touched you." she commanded. Jerome obeyed. He had one arm braced against the table and snaked the other one to reach between Cecilia's leg's. His fingers found her nub and started rubbing in circles against it. The motion sent sparks coursing through Cecilia. She wasn't going to last much longer. She felt her core muscles spasm and she ground her hips back into Jerome. She screamed as her orgasm ripped through her.
Jerome, in turn, almost immediately increased his pace and bellowed as his climax started almost the moment that he felt Cecilia's inner muscles spasm and tighten around his cock. This time, he actually found release. He thrust into her madly as he finally exploded passionately. He pulled out, finally spent.
He looked at Cecilia, who was still breathing heavily. She flashed a grin at him.
"How was it?" she asked.
"Intense." He panted. "Probably the best orgasm of my life. But I'm not sure if I would want to experience that every time."
"We expect that our drug would probably be used on an occasional recreational basis. We aren't recommending daily use." Cecilia responded.
Jerome grinned at her. "I think you will find a market for that."
