Left the frat party early.  

Saw the sorority girl his frat bro was trying to score with. Knew his buddy did not have a chance, since she had a reputation for being frigid.  

Went upstairs and crawled into his bro’s bed to wait for him. Knew he would need to release the cum built up in his balls after a long, frustrating night of flirting.

Wanted to be there for his friend.
