He WAS stronger than her. He probably would've let her keep him down like that, but when she kneed him, that changed things. He flipped them over, with her pinned underneath him. "Yea I have been watching your videos and you know what? I loved every fucking minute. Gotta say little sis you're real sexy." As he spoke he started playing with her pussy. "I've wanted to fuck you ever since I first saw those videos, on the same day you got here. I found out when you left the room to go to the bathroom. And as for torturing me...let me make a few things clear." He spread her legs apart as he shoved his member into her, sighing as he felt her walls around him. "First of all, I'm stronger than you. Secondly, this house is locked and the key's somewhere you won't find it. Lastly, even if you do have drugs stored away, they won't last forever." Each time he pointed out a reason he thrusted into her harder.
