"I never fucked Jeanie Dugan," he panted, still driving into Samantha. "She played with me a few times, but all I ever got from her was a sloppy handjob and some blue balls. Like I had the night I found you jacking off."

Sammi smiled. "And we decided it was a shame we should have to hide our frustrations, so we started off by diddling in front of each other, and then you had to put your finger in me."

"And you had to get my cock in your fist, so I'd know what it feels like, and…"

"Oh, God, Stevie, you fucked me, and shot your cum all over my belly, and I swore I'd never do it again…"

"But there you were the next night, sneaking into my room and, crawling into bed with me… you played with my cock till it was hard."

Her pussy slurped his thrusting cock, swallowed it deep. Her legs scissored around her twin's body, and her uplifted mouth was an easy target for his passion-charged kisses. The water sprayed onto his face, splashed onto Samantha's, but she didn't care now.

"Did you really never fuck Jean Dugan?" she gasped, riding him hard, massaging his prick with all the muscles of her supple pussy.

"Yes, I fucked her," he grinned, "but not very often. She wasn't half as good as you, then or now."

"God, I can't stand it," she groaned. "Feed me that big fat prick of yours. I think it's gotten bigger since last time, hasn't it?"

"Gets big for you, Sis. It always did and always will."

"Then prove it, fucker! Use that big cock to make me cum!"

He slammed it home on her command, pushing till the cum-bloated knob of his prick must have been halfway up her belly. The raspy bristles of his pubic hair were like a wire brush on Sammi's cunt, and she rocked and rolled, mashing her cunt against his groin.

"Now," she gasped, "now, fuck me now!" He shoved her ass hard against the shower wall, his prick driving and biting deep into her supple cunt.
