We had a day off and went to a public spa. For the people that are unfamiliar with that, it’s a place with sauna’s, swimming pools etc. During your stay, most of the time, you’re naked. Everyone is so it’s not a big deal and everyone is just minding his/her business.
My gf loves to tease, so during the day she kept touching my dick, let me touch her and kept spreading her legs giving me a good view of her pussy. You can imagine my balls wanted to bust.
At the end of the evening most of the other guests visiting went home leaving it less crowded. We sat down in a sauna that was not too hot. At first we were alone but after a minute an older (guess 50+) guy also joined the sauna.
I was sitting and my gf laid down on her back with her head against my hip. He sat like 3m across. I was already pretty horny because of the day so I just started caressing her body and playing with the skin around her nipples. Normally this kind of behavior is not done but I thought he wouldn’t mind.
