Photography assignment [MF]

My friend was over and she was telling me about her photography assignment and asked if I would model for her. I said sure, I’ll try anything once. I started doing yoga and she snapped a few but she didnt like how the clothes turned out. And she said light looks better reflected off the creases of the muscles. One thing lead to another and i found myself butt naked being photographed upside down. While i was upside down she said stay very still and was walking over while telling me how she’s a fan of asymmetry and very gently moved my cock to the right.
Sufice to say that was the most fun i had doing yoga
