During the time when my family was away, my cousin decided to stay at our house for three days. She still looked like a child, but she seemed very interested in adult things and teased me into temptation! "Onii-chan, don't you want to do H with Yui? I want to," she actively tempted me, and we did it raw... "Hey, Yui can still do it, let's do it one more time." In the bathroom, in the bedroom, even when I woke up in the morning, she would sneak into my bed... It was a record of three days where we only had unprotected sex.
