When I was younger, 25 at the time, my fwbs and I went to our city’s nude beach. My fwbs was 40 year old bbw. Big tits (not sure what size), short like 5’5”. She had never gone to the nude beach but I have several times. So we went during a hot day. We found a spot a bit far from one of the entrances but there wasn’t much people on our side. I got naked once we got a spot but she didn’t want to get naked, she was a bit self conscious bout her body but still had her bathing suit on.
Some time goes by and more and more people pass us. My fwb knew I like being naked and I get turned on when others see my dick. Anytime, someone was coming close to us, she would whisper things like “I want your cum all over me” or “I wish I can suck your dick right now” just for me to get hard and show off.
Two girls passed by but stayed somewhat close to us. I didn’t stare at them as I tried to suntan. But my fwbs would notice them keep staring at us and she would tell me that they want me and telling me naughty things. She eventually started fondling my balls and I got really hard. I was just staring off in the sky and she would say “these girls are staring at us and your big cock”. I couldn’t any more, and she made me cum all over my stomach and cock. She cleaned me up with her shirt so she can wear it on her back to the car.
