Sauna Sex!!! Amazing

Got to share this story, am in europe travelling meeting family and sking. i have been staying over at my inlaws place in germany. I helped fix the sauna as it was not working for the last 3 years and instantly my wifes mums mates have been coming over to use it. Well earlier today my wife and her mum went out to shop as we leave to hit the slopes tommorow and i was left alone after working out at the gym. I came back to use the sauna and when it was ready i here the bell ring and its my mother inlaws 45 year old friend, milf tastic!!! she has been giving me a hard on all this week. Anyway she came over to use the sauna and chat to my mother inlaw. I explained everyone was out and she said as she is here she would use it if i did not mind, i said i was cool with it. In the sauna room i am in there with my boxers and towel she comes in with her robe and takes it off outside revealing a massive pair of tits and no panties. she asks me why i am wearing boxers and a towel round my waist as the sauna is a naked experience in germany and says its un-hygenic, she tells me to take everything off. i did not hesitate and said as a sign of respect i was wearing my boxers as she was there, she laughed and said that was very sweet. 25 Mins and i am swaeting away am lying on my stomuch and my arse is in the air with sweat dripping i have been avoiding her as she is just sitting there legs open and her massi.ve tits facing me, i already have a semi which i am trying to hide. she starts talking to me now about my body is in good shape and that my arse is turning her on in this position, so could i change positions and sit the other way round. I get up revaling my almost hard cock which she smiles at and says that better. she carrys on talking about what my wife told her a few nights ago, girl talk she called it and said she admired me for spending so much time on going down on my wife!!! am gob smacked she then says she has never had a lover do that and opens her legs further, i csan hear my heart thumping and my cock is rock hard now and i cant hide it. she laughs and says just teasing you, your wife said you can get embarrassed easily. Anyway I leave to take a five minute break cold shower, she does the same. She then goes back in i wait a few minutes and open the door to see her with her arse arched towards me and the door. she tells me to come in close the door and she then just pushes her arse into my cock, i just cant say anything she then turns around grabs my cock hard and pushes me against the sauna. She says thats it am going to use you as my toy, and puts half my cock in her mouth, i tell her i cant my wife will be here any moment and she says no she arranged for them to meet another mutual friend and she had the whole afternoon to use me. I try forcing myslef away but its just so diifcult am horny she is fucking got my cock in her mouth and she starts to suck my balls. she starts moaning and whilst licking my balls she uses here hands on my arse to push my cock further in her mouth. got to go now will tell you later the rest!!!
