I'm nothing at school, but when I get home, I can see my defenseless sister's body all I want! Plus, every night I mess with her sleeping body and secretly get excited. No matter what I do, she doesn't wake up, so my actions escalate! Unable to hold back, I insert my dick and do slow thrusts... it feels too good, taboo internal ejaculation! Then, when my sister wakes up, instead of getting angry, she's incredibly aroused!? This time, she herself seeks out my dick, rides on top in a cowgirl position, and demands internal ejaculation over and over.
