It's my first time living alone and I'm enjoying a carefree life! But at night, a girl from my class comes over and says, "I have to get up early tomorrow, so let me stay over." She knows I'm a guy she can't lay hands on, so she goes to sleep in a very vulnerable outfit. I watch adult videos to relieve the sexual desire that's built up in me, but... While I was engrossed in watching adult videos, a female classmate was watching them quietly behind me, holding her breath! Then she started to ask for me, breathing heavily! Adult videos are the trigger for my arousal!
