Amy pushes

"Go take him, big boy," Amy whispered. "His ass is lubbed up and stretched out for you."

"But I can't, that's Kate's brother!"

Suddenly I felt her grip my hard cock through my pants and squeeze.

"Little Alan says you can," she said. "I'll watch from here and make sure nobody interrupts the fun."

"But Kate..."

"Is the least of your worries," Amy said. She slid a hand down my pajamas and started stroking my shaft, then leaned in and kissed me. "You know you belong to me. Your average sized cock and your cum filled balls belong to me. I gave you Kate. I gave you David. And now I'm giving you Jimmy. I can easily take it all away, if I want. I could see that Kate gets that video next. Or maybe your mom and dad. Could you imagine?"

God her hand felt so good stroking my cock, and in the next room Kate's brother was still moaning my name as he fucked his own ass. I wanted him. I didn't want to admit it, but I did.
