Every time she gave me a massage, I got rock hard. I just couldn't help it. No matter how hard (pun not intended) I tried her soft gentle hands, and her sexy body and friendly disposition gave me a massive hardon every time I went to see her. Despite leaving with blue balls, I couldn't resist going back and having her massage me again.
It was under these conditions that I found myself back for my usual massage with only one slight modification. Instead of being nude under the towel that she would have me wrap around my waist I was wearing her panties that she had given me the day before promising she would finish me off if I wore them when I came back. I was, of course, way to horny for her after so many massages to even think about resisting. So here I was with nothing but a towel and lacy hot pink panties on as she came in.
"Ready?" she said with a cheeky grin.
"Oh yeah." I said with plenty of excitement. Before I could even react, she reached out and pulled the towel off of me leaving me standing there in front of this sexy woman wearing nothing but a pair of lacy hot pink panties with a very pronounced erection. I felt heat rise in my face as I saw her eyes lock onto my lace covered groin area and grin.
"Mmm very nice." she said. "I see you like wearing my panties." She must have seen my face going red too because she added, "Don't be embarrassed, you're not the first guy to discover he gets hard wearing panties."
She then laid me back onto the table face down and went about her usual business of massaging me. The massage was good as usual but also quite awkward and uncomfortable since I was already hard, and it was pressing against the padded tabletop. I think she extended my back massage just to tease me, but I can't say.
