I enjoy getting massages, both legit ones and those that provide 'happy endings.' I went to a new place near my work a few days ago. It was an Asian massage parlor, I initially expected a bit 'extra' would be offered (for a price). The gal led me to the room, and asked that I prepare for my massage. She pointed to a sign stating 'no sexual activity.' So I no longer expected anything extra. Though she was quite attractive, I wouldn't have been against a little extra.
I stripped naked, face down. She draped the small towel over my butt. She gave me a decent massage, not great. When she was massaging my butt cheeks, I started to get hard. Almost as soon as she was finished with that area, she told me to turn over, uh oh, I was still rock hard! I've gotten erections during legit massages before, but the massage therapists are usually very nonchalant about it.
When I turned over, the gal said 'what's this!?'...I just quietly apologized. She draped the towel over my crotch, but it slipped off during the massage and she didn't bother to cover me up again. She said something like 'I can't touch it', and I told her I knew that. She gave me a pretty good massage, including my thighs, which kept me hard. I even noticed a bit of precum as she worked on me while I was on my back.
When she finished, she left the room. I couldn't stand it, and started stroking my still-hard cock. While I was stroking, she came back into the room. I didn't even care, just kept going at it with both hands. She asked if I needed a towel and brought one to me. Then she stood there while I shot my load onto the towel! I came hard, several long spurts.
So in the end, I don't know if I just didn't know the right words to say to get something extra, but it was fun jacking off with her watching anyway. When I left, she said she hoped to see me again.
