As she spoke Rick felt his grasp slip and his cock followed its natural path. Very quickly his cock started to fill with blood. It was soon hot and heavy lying on his belly. The pressure and sensation made his head spin.
Rick began to grind his hips, fucking his willing mother's mouth. His cock lifted until it stood hard away from his body and cum began to drizzle out. Rick turned from Sarah, who's persistent stroking of his balls made them want to explode, and towards his sister.
Janet was looking back at him, not in support or concern, but with hunger.
She was definitely looking at Rick's cock as she stroked her hard cock. Sweat was dripping off her chin and her breathing was ragged.
This just made Rick even hornier, he would give anything to slam his cock into a pussy and plant his cum deep inside.
That was it, he needed that release, and he needed to come. His whole process thought switched from concern over his predicament to that of orgasm.
Rick had long ago learned that his sexual desires soon became the sexual desires of the women around him. Laura moaned and looked up from sucking his cock. Her brilliant green eyes looked at him, but she wasn't really seeing him.
Standing, she let Sarah remove her blouse and help her up on the table. Laura straddled Rick, her skirt hiked up her hips just covering her pussy, and started humping against the base of Rick's cock.
Rick's head spun as she ground against the ring mounted at the base of his penis. Her hands slid up and down the veined skin of his stiff erection.
"See what I mean?" Sarah said as she licked a couple of drops from Laura's breast. Laura moaned and ground harder against Rick in response.
"Not only is it pumping an enzyme into you that will keep you aroused at all times, just like Janet..." Rick looked over at Janet, her eyes rolling back as she remained barely conscious, pumping on her cock.
"But just mere physical contact increased the dosage."
Rick twisted his head from one side to the other, his body crying out for satisfaction. He wanted to scream, beg, do anything to get someone to fuck him, but even in this state he didn't want to give in.
He tried to communicate his need to Laura through mental commands, eye signals, his persistent grinding back against her wet pussy.
Sarah rubbed the sensitive end of Rick's erection. "I won't let her fuck you until you give in." She said as she brought her mouth close to his cock.
"I know some tricks of my own and you won't cum until your lovely cock is nestled inside some hot cunt."
As if to prove her point the red head slipped her full lips around Rick's cock head, her tongue circling the rim.
Rick groaned out loud as his resistance was overwhelmed with pleasure. The feeling of Laura's soft hands running up and down his cock and the transsexual woman's warm wet mouth overwhelmed his senses. His vision became almost tunnel like as he watched the women work on his cock.
And then they were gone.
Rick cried out softly "no..." as he looked up to see Sarah standing beside him. She was massaging Laura's full breasts, her hands over Laura's, occasionally pinching her nipple and licking the resulting milk.
Laura stared into Sarah's eyes in a trusting rapture. Rick's cock bobbed in the cool air to the beat of his heart, the burning sensation throbbing along the length of his rod and deep into his balls.
The pressure was so distracting; his head swam with desire as he struggled at his bonds to reach Laura's nubile body.
"p-please..." Rick whispered.
Sarah turned with a big smile on her face, a shit-eating grin. She had won, and she knew it. "Did you say something stud?" She asked patronizingly.
It was over; Rick knew he'd lost. There was one thing he needed. "Fuck me." He whispered.
"What was that? I didn't quite make it out." Sarah said as she gently took Rick's cock in her hand, stroking is slowly. Laura sat passively waiting now, eyes closed as her fingers circled her extended nipples to tease drops of milk from them.
"Fuck me!" Rick shouted, his cock stiffening even more with the effort. Rick let his head fall back to the small pillow, he tried not to look at Sarah, but instead concentrated on Laura's heavy breasts and slim frame.
All he wanted was to fuck her, to drive his cock as deep inside her as it would go, to fill her pussy with his cum.
"You may go ahead now Laura." Sarah said with a smile.
Laura opened her eyes and turned to Rick. Her eyes were wild with desire as she crawled on top of Rick once more.
Franticly Laura rubbed her slick pussy against Rick's hard cock. Sarah, obligingly, reached behind Laura and positioned the swollen cock head against her tight opening.
Laura cried out as she steadily slid back onto hard flesh until more than half of Rick's length was buried. Laura immediately began to moan and buck as her body released its pent up sexual tension into her first orgasm.
Rick already found it difficult to control himself, despite his orgasm moments ago.
Laura began pumping up and down the length of his cock, forcing it deeper with every movement. The hot wet confines of her pussy milking his cock, making his need to cum stronger with every thrust. Laura lay across his chest, her cheek against his, the smell of her hair in his nostrils, her body tight against his.
"Cum for me baby..." She whispered desperately into his ear. "Give mommy what she wants, fill my hot, wet cunt with your fuck juice..."
Laura clung tightly to Rick, burying his cock as deep in her clenching pussy as she could; her sweat slicked body sliding against his.
Laura whimpered as she began to orgasm, her hot juices coating Rick's cock.
The sensation made Rick buck, unable to control himself, he shot load after load into his sex fevered mother. Each cry driving Rick to cum even harder, drive his seed even deeper.
Laura's pussy became slippery with Rick's cum. The sensation of her tight pussy lubricated by his hot cum drove Rick to a second spontaneous orgasm.
Laura still clung to Rick, her body hard against him as she became unable to react against the overwhelming sensation. A plaintive cry of pleasure and emotion emanated like a banshee's wail.
As his orgasms subsided and his cock softened inside Laura's still twitching pussy Rick lay back against the table. His head spun, He'd never felt such an irresistible need to fuck, to cum, before in his life.
He was worried what his genetically altered sperm was already doing to his sexy mother. For the first time in what seemed like hours Rick's thinking wasn't controlled by his need to mate.
He guessed this was similar to the effect he had on women when he wanted them to fuck him, when he forced them into heat.
