Her eyes wide as she stared and struggled for a response. Instead she whirled around, screaming out, “Mom!” and stormed from our bedroom.I couldn�...�t help but smile for my fleeting victory. They were rare and I was sure that Sophie would get her revenge somehow.The smile fading as I turned back to my reflection in the mirror. My hands rubbing my belly.Sophie wasn’t lying. It was still bigger than it should probably be. Bigger than girls on the television. My hands moving to my hips and the small. So I spent the evening in my room playing video games halfheartedly and imagining what might be going on in my sister’s room.After my nightly shower I stood in front of the bathroom mirror while thinking about the girls’ sexy talk for the millionth time.

I guess I would be considered cute.Even with my red. "I really don't know, Canon. It may have known that we were going to mate and didn't want to spoil it for us. So it left the cave and caught something else to eat. Just wait until it finds the men we killed. The men had stripped and dragged the bodies to the forest. Those bodies will be gone by morning."At my mention of our mating, she hugged me tighter and smiled a million dollar smile up at me. I stand over a foot taller than her and I was anxious to get a look at my prize. It was sort of. She only mumbled on my cock and kept sucking me with the same passion while cupping my balls in her hands, massaging them eagerly to take me over the cliff and I had to quickly lean against the wall for support, feeling her tight lips clamp like a vice around my cock and I started shooting my load in her mouth. I stayed motionless while she continued to milk me until I was beginning to go limp; with my eyes closed to savor the moment as long as I could.Feeling the elation diminishing; I opened.
