My senior's girlfriend is someone I secretly admire. She's fair-skinned, cute, and has big breasts. On Friday nights, I went to my senior's house, where I live with him, for a drink. When everyone else had gone to sleep, she started kissing me and letting me touch her breasts. The next day, my senior 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.
