Seduced Willingly

She hiked up her dress and straddled my back, immediately pouring a lotion or oil on my back that was warm. I could feel her warm soft inner thighs on my sides. She started with my back and moved down my back until her crotch was straddling my ass. She was working my muscles and spreading the oil. I could hear her starting to breath harder and I could feel her making suttle motions with her hips driving them into my ass. For the first time, I confirmed that this was no girl. I could feel her hard cock resting between my ass cheeks.
She must have had on lacy silky panties, but cause as she picked up the rythm doing my back and lower back with her hands, her cock was slowing sliding up and down. I was literally having butterflies, I was probably trembling in my thighs and precum was leaking out of me like a faucet. I was more turned on now, than every in my whole life.

She moved her hands down to my ass and moved her hips down to my legs, still straddling me. At this point, she said "My dress is getting oil all over it, do you mind if I take it off?" I said "well, that's fine." She then said "look, I know you're straight, so I don't want you to think anything, it's just an expensive dress, if you want me to stop the massage that's fine, but I don't want this dress ruined." I said no, my voice shaky, that's okay.

After removing her dress, she was in a little g-string with a bra. Her g-string was white silky and lacy around the edged as I thought it felt like on my back and ass when she was straddling me. I peered behind me, while I hiked a couple of pillows under the my chest so that my head and upper body were propped up a little. For the first time, I finally saw her panties bulging out with a hard on. Her panties bulged out and I could see the outline of her rather large cock behind the veil of silk and lace. I could see her ball sack slightly showing on the edges of the skimpy panties. This was indeed a shemale.

She began massaging my ass through my boxers.
