Here is a mild and tame story, but I like it:
My wife is sexy but very conservative and even gets embarrassed being naked in front of me with the lights on (although I think she secretly wants to be an exhibitionist but that's another story).
Anyways we're at a vacation resort and she's getting her first ever massage at the spa. She goes there in comfortable clothes (tshirt, sweats, thong underwear underneath - and let me add that even wearing thongs is new to her...she only started wearing them recently). She comes back from the massage glistening from the oil and tells me 'Oh my God, I had a MAN masseuse!' She tells me how when he walked in she got extremely nervous thinking 'My husband is going to be mad!' So I was joking with her about it and another man touching her and she said 'And I was soooo embarrassed! It was cold in there and the sheet was soooo thin!' ...and at that point she sticks her fingers out by her chest indicating that her nipples were sticking straight out and poking through the sheet (and i’ll add here that her nipples stick out quite a bit when hard, either cold or aroused, those things are VERY visible.). I joked that the guy must have sure enjoyed the view and she said 'I don't know, I had a towel over my eyes!' but then she did a hand motion like she had a sheet over her chest and pulled it up/down/up/down over her boobs which I guess meant the masseuse kept adjusting the sheet exposing her boobs. At this point I'm wondering how professional even are these masseuses in foreign countries...in the US those guys have licenses and do everything they can too keep you covered and comfortable...but over there this may be some guy who walked in off the street for all I know
. At the very least it sounded like he wasn't exactly concerned about draping and was enjoying getting some guilt free peeks at this American girls tits and rock hard nipples!
We joke some more about it and some point she walks behind me and says 'and he was all doing this'', and starts rubbing my butt up and down and massaging my butt and at that point I remember 'oh yea, she was wearing a thong!', which again, for her, having her ass in a thong visible and being massaged by another man would have been so embarrassing (or maybe arousing)
Even here in the US if they're wearing a thong its a sign they want their gluteus worked, but for her she never would have even thought of that otherwise would have worn regular panties. So here she is, getting her bare butt worked over by some strange man, and she kept telling me 'the whole time I'm thing my husband is going to be so mad this strange man is rubbing all over me!'
She did say she finally relaxed towards the end. Also, knowing her, I still think being naked and getting a butt massage by another man was why her nipples were hard when she turned over, and not the 'cold' like she said
Anyway, that's all there is to the story...like I said very mild...but would love to hear more that are similar.
