My best friend's little sister is coming to stay with me for 7 days in the house I share with my best friend. She looks cute. But she's actually a little devil... "Excuse me," I hear a voice from the bathroom, and when I go to check, she says, "Where's the soap?" She shows me her naked body and seduces me! She seduces me to enjoy my reaction, but I'm always waiting for the insertion! And on the 7th day, I finally can't hold back and I insert it into my little sister! I had sex with her many times while my best friend was away.
