My senior's girlfriend is someone everyone secretly admires. She's fair-skinned, has a big ass, big tits, and is cute. On Friday nights, I went to my senior's house, where I live with him, for a drink. While we were drinking, she kissed me when he wasn't looking, and let me touch her breasts. The next day, he went on a business trip. For the three days he was away, I had sex with my senior's girlfriend. She said she was OK with raw sex, so I came inside her over and over again. It was a dreamlike three days.
