[mf] Unexpected sex in the mud room

Went to my local small spa with my friend. We have been friends since we were like 10 years old, holidayed together, key parts in each others weddings and there for each other during the divorces.
We have been to this spa a few times but they now had a new mud room. Not knowing much about it we decided to book it. They showed us to it and said this room you can be completely naked as you can lock the door from the inside. We locked the door and weren’t sure about being naked but my friend just said lets do it.
We got naked and covered ourselves in mud and sat in the benches. I couldn’t help but keep checking her out, I got hard and couldn’t hide it. She spotted it, at first didnt want to look at me and I apologised. But then she came over and started giving me a handjob. I started to rub her clit and insert my fingers. I told her to get on me and she rode me until we both came…
Safe to say we have been the spa a few more times
