A concert.

Jamie had offered Alex her ticket to a rock concert on the condition that her boyfriend Rex, who was 19, chaperone him since he already had his own ticket.

Alex agreed, knowing that this was the perfect opportunity to have some hot, anonymous dick ride his hole to orgasm in a dirty concert bathroom stall.

Alex also liked Rex, and trusted him to keep him safe if someone tried to attack him.

Rex was the jockey type with the washboard abs, broad shoulders, and good looks that attracted his adorable little sister. He also seemed content to wait for her to hit 18 years old before having sex with her. Saint, or just in love, Alex wasn’t sure, but he was always nice to Alex when he visited - Rex went to a community college about 15-20 minutes away.

Finally, concert night was here and Rex was outside in his truck waiting for Alex to come out.
