Few years back i was with my exgf and her family on 1 week vacation in thermal baths. We went by camper, So limited space and no privacy. But because we were in swimmsuit the whole days, we were extremely horny. So after a few days, we sneaked in changing booth together a Went directly to business. We had bathrobes (normal there), me with swimming short, And She was naked. Imidiately we were on each other. She licked my cock a few times but IT was already rock hard. I turned her around, Bend her over the wall And slipped inside. She was very wet So it was so easy. But She started to moan, So i had to cover her mouth, even though i thought Its so hot that other ppl (usually quite old) knows someone Is fucking there. It did not take long and i already Felt her cumming on my cock. Then i came hard all over her ass. It was very short but very hot, and we became regulars in the booth.
