First Masturbation by Other Man

My friend told me that there is a great massage center nearby. This massage center also provide body scrub service. So, I went there for the body scrub service. I have to be totally naked. This is the first time I'm naked in front of another male. I'm naked and lying on a bed. He started to scrub all over my back. After completing the back, then to the front. He applied lotion all over me and started to scrub my entire body. Then, he concentrated on my penis and balls. He gently squeezed my balls and stroked my penis. His intention is only to scrub, but I ended up cumming all over. Finally I have to apologize to him.
