You look beautiful I said. She beamed at me and sat down again. She rested her hand on my knee and took the bottle from my hand. Let me help you she s...id and started to oil my legs. You’ll get this stuff over your new clothes I warned.No problem she replied and promptly took off her top, then slid of her shorts, putting them back in the bag. No it’s safe., She worked up from my feet and when she reached my knees, her hand slipped between them and she started to oil my thighs. I let her part. "Oops! Sorry!" "It's okay!" I replied, laughing it off. As I started to stand up, I saw Jake come over to me. "Hey, are you alright?" He spoke, offering me a hand up, which, of course, I took. As I stood up with his help, I noticed that my friends had skated off and were leaving me alone on purpose. "Yeah, I'm fine," I said, thankful that he couldn't see me blushing because of the lights. "Good, oh, and happy birthday," Jake said, leaning in towards me. His arm bent back, pulling me in towards. And Sunday our institute was closed and all the trainer were on leave. Now only thing we had it was Sunday.And there is now way to say no to a girl as beautiful a her. So I said ok, though I am not a trainer by profession but still you can come on Sunday i’ll help you out with general q&as. I dont know why but I was to excited to meet her alone since there was no one in the institute apart from her and me.We started our session with all sincerity and and there were some laughter breaks during. Mistress continued to work her way up my body until I felt her raise her body up on her extended arms. Slowly she eased forward until I felt some cool and supple poking around between my cheeks, my ass cheeks. It was then that I realized Mistress had a strap-on. That she intended to use it, on me. This truly was going to be a first, even if it was number five. I braced myself for what was to come. I could not help but to wonder what was to come, I had no idea what size Mistress had decided.
