He's hanging on by his fingertips

Matt grit his teeth, pulled mostly out, then rammed himself back in. He couldn't turn into a minute man, he had to make this work. . His sex performance to date had been mixed but he wasn't going to let Tanya down.

Even if she looked like she could keep going forever.

She'd told him how her father had sexually exploited her but her pussy was incredibly tight, its muscles gripping him as he supported his weight with his elbows, brought his hands to her perfect breasts, and hammered into her again.

"Nice, Matt," she whispered.

He nodded, afraid that he'd lose control if he tried to speak. His brain was at war with his balls and needed every ounce of will-power he could give it. Especially because his pervert sister was now stroking his balls and tongue-diving his asshole.

Which felt great. Watching porn might be one of the world's great wastes of time but having a sister who watched porn was a gift from the gods.

"Make me cum again," Tanya said.

He didn't answer with words but he kept pumping away... and kept trying to control himself. God, it would be great to cum into that cunt, to squirt out inside of her and then to pull out, still squirting, and coat her tits in a warm frosting.

She squeezed down on his dick. "I practice my kegles," she said.

Yeah, he could tell. It wasn't helping with his self-control.

Hank Aaron, he thought to himself. Career batting average of 305. Lou Gehrig, career batting average of 340. Shoeless Joe Jackson, 356. Arod, 295. The Babe, 342. Reggie Jackson, 262. Poor Reggie, but hell, he hit like a demon when the stakes were high.

Keep going, Matt, he told himself. Keep going. Girls come first. If there's one rule to live by, that's it.

"Ah...ah...ah, ohmigod." Tanya's pussy muscles clenched down even harder and she threw back her head in what looked like pure celebratory joy. "Jeez, you did it. I came again. I've never cum twice in a row like that."

He wondered if she was on birth control... surely she was but he couldn't remember her saying she was and who knew, maybe her father had a vasectomy to keep from impregnating every other Hollywood wanna-be star.

Tanya looked into his eyes. "Are you going to fuck me, Matt? Are you going to make me cum again? Are you going to ruin me for any other man with your hot fucking?"

Matt could promise the first. As for the second two, all he could do was give it his best shot. And that's exactly what he intended to do.

He resisted the urge to grasp both of her arms in his hand. She might freak if he acted out any **** shit considering what she'd gone through so he supported his weight with his arms and started pumping.

Her pussy had been soaking wet from the start and had only gotten wetter with her orgasm but her muscles cranked down on him hard enough that it was still hard to concentrate on anything but pure sensation.

She looked up at him and smiled... an expression unlike the normal cynical glare she approached the world with.

He lost track of time, wallowing in the moment, making love to a beautiful woman who, only days before, had thought he was worse than shit sticking to her feet.

"Oh," she whispered. "Oh. It's coming. I can't believe it."

He pumped harder.

"Aaaah." It wasn't a scream, exactly, but it was pretty close. "Cumming," she shouted. "God, cumming again."

And then, all of a sudden, the urge built up in him. He was going to cum and there was nothing that could prevent it.

A part of him wanted to stay inside of her, to damn the consequences. But he suppressed that part. He pulled himself out and came on her beautiful tits, shooting wad after wad of cum on her.

She looked down at her boobs, then rubbed them together, smearing his cum into her body like some kind of high-end lotion.

"That was hot," she said.

"That was hot," Karen agreed. "Can I... I mean, would you mind if I licked that off?"
