"Oh yes!...Yes!...Ooh..." Polly panted as she writhed under Mike's persistent thrusting. Her eyes tight shut, she couldn't see his expression of grim determination as he held on to his load far beyond what he'd previously considered possible.
As he saw Polly's face contort in the brief ecstasy of orgasm, he gratefully came inside her, growling through gritted teeth at the relief of that release. His semen boiled from his cock, hosing Polly's twitching cervix as Mike thrust hard into her two...three more times. Feeling her cervix press momentarily against his post-orgasmically hypersensitive glans, he sighed with ecstasy and pain, his hips finally ceasing their grinding.
Polly sank limp against the mattress, humming in contentment as Mike rolled from between her legs and slumped heavily beside her, his breathing slightly ragged from his exertion and his slick cock softening against his thigh.
"Hmmm." Polly purred. "It's been far too long. Thank you."
"Your welcome." Mike murmured sleepily.
"No nodding off on the job, Mister." Cassy leant over the exhausted man and kissed him deeply, finding herself being kissed back just as forcefully. Good! He wasn't as spent as he looked. The spirit was clearly still willing, even if the flesh looked weak.
As Polly's twin administered the kiss of life, her hand withdrew from between her own thighs. She broke off the kiss and pressed three moist and pungent fingers to Mike's lips. "That's what watching you two has done to me." She smiled wickedly as Mike parted his lips and drew her fingertips into his mouth, suckling on their tips like an infant. "We had a deal, Mister. You'd better be able to keep up your end of it."
"I don't think that'll be a problem, Sis. Look down." Polly propped herself up on an elbow and came to Mike's defence.
Cassy glanced down the bed. Sure enough, Mike's penis was stirring. Both twins reached for it, ten fingertips caressing it back to full vigour. Cassy watched it grow with greedy eyes. It was a fine specimen: That was for sure. Long, thick and heavily veined. Judging that he was as hard as he was going to get, Cassy lay back and flung her legs wide.
The speed with which Mike took up the invitation surprised – no, delighted her. "Michael, Dear."
"Yes." He looked down at her solemnly, his cock unmoving inside her.
God! She thought. That feels wonderful. Sis was right: it's been too damned long. "I know this is a cash deal but you are allowed to enjoy yourself too." Cassy had noticed how – workmanlike was the only word for it – how workmanlike his servicing of Polly had been. It was like he was trying to avoid intimacy even while having sex. Sweet boy. "Now earn your money. Giddyup!" Her heels kicked at his buttocks and Mike took the hint, thrusting hard, deep, fast...

Mike had known the twins for several years, ever since they'd returned to Bridgehampton from University in England. They'd become friends when the twins had hired a local handyman – him - to fix up the shop for them. Ever since, he'd been dropping by for coffee on quiet mornings and shooting pool with them in their local bar.
He'd watched with amusement as ambitious young bachelors foundered on the rocks, trying to win one of these two sirens. In all the time he'd known them, none of the guys had succeeded in getting anywhere near the twins – and many had tried, hard. For this reason, their proposition had taken him somewhat by surprise.
Being a casual worker, there were inevitable dry periods for Mike and, occasionally, he supplemented a meagre income with deposits at a sperm bank upstate. While this was not common knowledge, the twins were close friends and in the veritas of vino one long ago evening, he'd confided in them.
When he'd turned down a pot roast invitation last week because he was getting a free ride "upstate" with a removals firm he occasionally worked for, the twins had turned up at his house by Kellis Pond with their absurd proposal.
They wanted to buy his "deposit" instead. They'd discussed it and they both wanted babies. Moreover, they wanted their children as close to being siblings as possible, so they should at least share the same father. The trouble was the absence of said father.
None of the local hopefuls were even considered but Mike was their pal and, not beating around the bush, they were aware how much he needed the money.
Incredulity, disbelief, bemusement and realization that the twins meant it, pretty much covered the rest of Mike's evening. Finally, he'd agreed.
It was the most sleepless night of his life. He'd had a hard-on until daybreak, just thinking about fucking the twins – and they'd made it clear they were not intending to use a turkey baster for this deal. They'd said, practically in unison, that their children had to come from an act of love. Fuck! How often had he jerked off, fantasizing about those two? Now it was scheduled to actually happen he was rock hard but couldn't do anything to relieve his tension. He needed his sperm count high when they called.
Yes, it'd been a long week waiting for the twins' calendar: A long hard week.
* * * * *
Taking Cassy at her word, Mike relaxed a little and took time to enjoy his work. It was a fantasy made flesh after all. He'd never been able to tell the twins apart – they appeared to work hard at remaining identical – but now he realized that he wouldn't even be able to identify them by fucking them. Even the little moans and sighs, the smell of perspiration, the way Cassy's vagina pulsed around him – all were just like her sister.
Mike was grateful for the déjà vu feeling as Cassy started trembling under him as if she were going into some sort of seizure, signalling the onset of her orgasm. Manfully, he raised his game long enough to finish with a flourish of hard, deep thrusts, letting his seed spurt directly onto her cervix as it dilated during her orgasm. He'd done some research on the web and read that this was the best place to put the semen.
He didn't have the energy left to roll off her, lying instead, still sheathed inside her, his weight settling gently on her heaving bosom. The sounds of Cassy catching her breath were interrupted by applause from Polly.
"Bravo! Encore" That was spectacular!"
"No encores." Mike mumbled as Cassy's fingers entwined themselves in his hair. He turned and kissed her cheek. "Thanks Polly."
"Cassy" Cassy gently corrected him.
"Both of you. It certainly beats whacking off into a plastic cup."
"What do you use for... motivation at the sperm bank?" Cassy asked, her fingers still toying with his hair.
"Is it true they have porn collections?" Polly asked.
"It's true, but I don't bother with it: I can't touch those girls or smell, or..." he looked straight into Cassy's eyes "taste them."
Cassy dipped her lashes demurely.
"So?" Polly prompted.
"So... I can't believe I'm telling you two this..." Mike rolled onto his back and waited while the twins nestled against his sides. "Well, usually, I fantasized about you two."
"See Sis!" Cassy lifted her head to look across Mike's chest at Polly. "I told you he'd thought about it before we propositioned him."
"You were right, I was wrong." Polly conceded "Now please shut up: I want to hear this fantasy of his. Go on Mike."

Despite obvious attempts to make the small, windowless room comfortable, it managed to retain its clinical nature. Ignoring the stack of DVDs that the nurse had indicated before she left him alone, Mike settled himself in a chair and unbuttoned his jeans.
All the way here, some three hours by road, he'd primed himself by constructing a fantasy about the twins. He got hard now just thinking about them.
His daydreaming had got as far as discovering them skinny-dipping down by the bay. He'd stood on the shore; daring them to come out but only succeeding in making them stay neck deep in the cool water. Christ! Their nipples must be like diamonds in that water. The bay was never that warm.
