Watch and wait

I'm rather curious about what she'll say, so I wait in the shadows.

"Oh, that's easy. I'd say, 'Daddy, I'm saving my cherry for you. Please make me a woman.' Oh, God, Hunter. Now it feels better. Mmm, pound my ass."

I stand there, shocked. Kate wants me to fuck her and take her virginity! I was hard from watching them, but now my cock is ready to burst out of my shorts. I unzip and continue watching my teenage twins fuck each other. I groan silently as I stroke my hardness.

Kate and Hunter grunt and moan as Hunter takes Kate's ass. He gets a good rhythm going, and the two of them have a great fuck. In the end, Kate screams, "Fuck, yes, Hunter! Come in my ass!" before she quivers and shakes through a hard orgasm. In another minute, Hunter growls as he obviously unloads in his sister's bowels. I squirt on the concrete floor near a rag. The twins hold this pose, satisfaction evident.

"Fuck, your asshole feels so good, Kate," my son says, "I hope Dad takes your cherry soon."

I push the rag around, mopping up the spunk.
