Yesterday I went to a massage parlor and engaged with a CSW. It started off with slight body rubbing and very light kissing. Breast sucking. And then she took off her pants (left her panties on) and i proceeded to finger her over the panties. She then rubbed her butt on my bare penis until I ejeaculated on her butt over the panties. There was no penetration to the best of my knowledge. Especially because she was wearing her panties the whole time. Is there any risk here?
