A few years back, I was camping with with some friends. I (m34) woke up in the middle of the night. I could hear one couple obviously fucking. I started jerking in my tent. It was obviously good for her from her moans. I went out by the still going fire to get off. I must have been extra tired because after getting off, I fell asleep with my dick out by the fire. It was probably only a few minutes. My friends gf left the tent and found me dick out and all because she woke me up. She said she was going to the showers to clean up and I should clean myself. I was completely embarrassed. The showers were separate rooms but the big open kind. I showered but got hard thinking of her seeing my dick. I took the risk and went into her showers and said I her moans were amazing and asked if I could jerk for her. She was taken back. I was rock hard already. She said as long as I don't touch, and could be fast, it was ok. I would up cummimg in about 3 minutes. She did help a little by bending over and washing herself. I came on the shower wall and told her it would be amazing tonsee her lick it off. She said no so I left. The next morning at breakfast, she kept looking at me and licking her lips. I can only hope she did lick my cum off the walls.
