One day, my boyfriend's best friend, Tatsuya-kun, came to the house where we cohabitate. Maybe it was because the alcohol had flowed... and I had let my guard down. In front of Tatsuya-kun, who was asleep, my boyfriend and I ended up doing our usual naughty thing. Thinking that he might be watching... it only made me more excited... even though I knew it was wrong, I couldn't stop. A record of me cumming non-stop with my boyfriend's best friend during his four-day absence.
