The senior's girlfriend I secretly admire. She's fair-skinned, cute, and well-endowed. We had a home drinking session at the senior's place where they cohabit on a Friday night. After everyone fell asleep, she kissed me and let me touch her breasts. The next day, the senior went on a business trip. For the three days he was away, I went all out with his girlfriend. She said it was okay to have unprotected sex, so I ejaculated inside her repeatedly. It was like a dream come true for three days.
