My best friend's little sister comes to stay for 7 days at the house where I share a room with my best friend. Cute looking little sister. She's actually a little devil..."Excuse me." I hear a voice from the bathroom, so when I go there, "Where's the replacement soap?" Even if you tempt me to enjoy my reaction, I will only be impatient with insertion! And on the 7th day, I finally couldn't stand it anymore and inserted it into my sister! I had sex many times while my best friend wasn't there.
