eros-muse: Clarissa followed her lab partner arguing the merits of the experiment that she’d proposed. Their senior genetic engineering lab needed an incredible paper for either of them to get into the school’s PhD program. “Seriously Jeff, it’s only a little sperm, I mean you probably jerk it twice a day what is using it for science versus wasting it in a sock?” “Can you hear yourself Clarissa? You’re asking for a sample of my cum while walking down the hallway…” With a shocked gulp she looked around and saw that they were walking past a huge group  waiting for a freshman bio class and she could see the shock and interest in their faces as she chased after her lab partner talking about his sperm. Laughing she tried to make out like it wasn’t anything. “God Jeff, you make it sound like I want you to fuck me or something, I just want a sample for the experiment. Professor Ward would love what I suggested and you know it!” With a groan she followed him as he stalked down the hall and into the biology building’s basements abandoned corridors. The snick of a door closing behind them didn’t register as she stared at his face still trying to convince him. “Just imagine the papers we could right on genetic engineering if we could splice part of the genes from two sperm or eggs together. Seriously it would be ground breaking!” Clarissa wasn’t prepared when Jeff turned on her and trapped her between his body and the wall an arm on either side of her head. “Clar, the only sperm you’d get would be the ones I’d dump in your pussy. I don’t donate my body to science only my mind.” The growl in his voice and his words sent a jolt through her as she stared up into his face. He was only inches away and Clarissa could feel her panties getting wet and her breath speeding up as he looked down into her face. His eyes widened and then he leaned in until his lips were barely brushing hers. “Holy shit Clar, You’re getting hot on that idea…I can see your nipples through your dress.” Whimpering Clarissa felt her legs pressing together trying to put pressure on her aching clit and then suddenly Jeff’s lips were on hers. He didn’t let her go, didn’t let up as he conquered her mouth. She moaned into his mouth as he tasted her, his tongue sliding through her lips and warring with her tongue. She didn’t even notice when his hands slid under her dress, she barely noticed the sting of her panties being ripped and tossed across the bathroom. Every ounce of her focus was on the way his lips were consuming her mind and soul and she was letting him. Jeff’s hands suddenly lifted her into the wait and Clarissa flailed until she found something to grab onto, only getting hold for a moment before she gasped again as her lab partner filled her, his cock sliding deep into her body as he flipped her legs up over his shoulders. “You’re so fucking tight Clar…” His cock slammed into her making her whole body shudder as she whimpered and clung onto whatever she was holding. His cock was amazing, he was in her and fucking her and Clarissa tried to ask herself why she hadn’t done this with Jeff before when she stopped thinking as his cock slammed against her cervix and Clarissa learned that she loved a mix of pain in with her pleasure. Every time he hit her seep inside she let out a little yelp of pain before subsiding into a soft moan as he withdrew. It was amazing, each hit kept her on the edge of crying out, just shy of being an ache, too soft to sting but just enough to let her know it wasn’t exactly good even though feeling him stretching her, filling her that deeply felt so amazing. Clarissa couldn’t make heads or tails of what she was feeling as she hung onto the ride while Jeff slammed into her again and again. Her mental clock said two hours passed but less than ten had ticked by in reality before Jeff was panting and struggling to keep his thrusts regular. “I’m gonna cum Clar, I’m gonna nut in you! You want my sperm, here it fucking is!” He roared that last works and Clar knew there was no way to escape, no way to tell him about the reason she suddenly remembered for why she’d never let him in her panties before. Her allergies and body hated birth control, a whole bunch of side effects kept her from using anything but a thin latex barrier to keep her from being full of a baby and the irregularity of her period kept her from tracking a safe period. So his shout and the feel of his suddenly driving deep and then throbbing as he pulsed soothing heat right against her cervix told Clarissa that she was being flooded by Jeff’s cum, every drop pouring right against her opening and flooding into her womb. The thought of it was too much, too exciting and Clarissa found herself clinging white knuckled to her handhold as her legs trembled over Jeff’s shoulders as she cried out her own climax. She could feel herself milking him, her orgasm pulling every last drop of him into her and helping push it along to her womb. Her advanced reproductive biology class had told her the reason for female orgasms were two fold from a biological perspective. First was to keep a bipedal human woman too exhausted to stand up and let all that life making cum leak out of her, the second was to help her cervix flutter, opening and closing in a bid to pull as much cum as could be deep into the womb for the best chance to get pregnant. “Fucking hell Clar.” Jeff’s last groan as he pushed the last of himself into her had her gasping and trembling. His hands held onto her as he slowly moved her legs and when Clarissa tried to stand she found herself in Jeff’s arms as he held her up from where she’d collapsed towards the floor on legs made of rubber. His eyes looked into hers and she could see the worry there until she smiled at him. “That’s one way to collect a sample…” Her breathy laugh as she struggled to get her panting under control set him off as he held on to her. “I’m so sorry Clar. You just kept going on and on and I lost it, are you okay?” He looked at her worried again and Clarissa felt her insides flutter at the concern and genuine care there. “If I were any more alright I would have in a heaven I don’t think exists. I’m pretty sure I got the closest I’ll ever get anyway.” The pride that flashed across her face had Clarissa mentally shaking her head at the Neanderthal part of men that never went away. “I came so much in you though are you safe?” He was looking down where she could feel what felt like gallons of warm cum leaking out and starting to cool into gooey sticky runs as it slid down her inner thighs. “Nope!” Her cheerful answer had his head snapping up to look at her in shock. “I’m allergic to most birth control and my cycle is so irregular that I have no idea. You might have just pumped twins into me for all I know.” She could see the indecision in his eyes as he looked at the mess between her legs but she’d seen how her mention of the risk had made his breath hitch again as it sped up. “Does that get you hot and bothered, you Mr. Scientist all horny over the possibility you put your baby in me?” Clarissa loved the groan he let out as he stepped back to let her lean against the wall and she watched his messy cock bob in the air with renewed hardness. “Jesus Clar,” The frustration that leaked through his voice had her stepping forwards with shaky legs as her dress fluttered back into place to cover her body. “I think you should come back to my apartment and help me find some new panties to replace the ones you ruined.” Her voice was teasing and inviting and she watched as Jeff’s head snapped up again. “I think we both need a shower to clean up the mess…” Her finger tapped Jeff’s cock coated in both of their fluids before she stepped back. “A good scientist repeats the experiment to make sure they got the right results…I think I need to know if your sending me to heaven was a one off or a true measure of your abilities…” With a groan Jeff tucked himself away and followed Clarissa out of the bathroom and towards a month of crazed wild fucking any moment they could find in any place they could find. The two of them started rumors around the campus about the best spots to get it on in public without getting caught, or at least mostly without getting. A month of perpetually leaking white gooey cum into her panties and Clarissa found herself settling into her lab partner’s lap while she tapped his chest. “It seems that one experiment was a success at least.” His confused expression had her giggling as he wrapped his arms around her. “We’ve proven that if you cum in a fertile young woman enough she’s bound to get pregnant, it’s a repeat of the oldest experiments back to the cavemen but we did it…” Jeff growled and threw her over his shoulder as he carried her towards their bedroom as she squealed and kicked through her laughter at his caveman antics until her sounds turned to moans as he spread her on their bed and proved that her pleasurable trip to heaven still wasn’t a fluke. Not that she’d ever tell him she had enough data to prove it, experiments need to be repeated… -- source link
