Transgender & Crossdressers

The evening after Ashley and I showered together, she suggested that we start exploring herbal supplements. It came from her complimenting me on my girlish ways and didn't I wish I had breasts like hers. It progressed to the point that I admitted that I would love to have breasts. After hearing that, she told me about her limited research into the subject. I...

XXIX "Any woman out there" We went upstairs to the main bedroom. The girl was clearly coming out of it. She was breathing in long, deep, happy sighs and she turned her head when we entered the room. Her eyes, no longer glassy, sparkled as they fixed on me, apparently hardly noticing Wendy. I walked to the foot of the bed and stood there with my legs somewh...

by The_Technician on Jan 8, 2019
Sci-Fi & Fantasy

Marcella Henry watches over a sentient computer at night. What she doesn't know is that the computer also watches her. This is a GEEK / NERD story. The beginning is very technical and is not at all sexy. The last portion gets sexy. Depending on how this is received, I will most likely be writing additional stories of PLATO, Helen, and others. They won't nee...

Gerig was in his study, adding up the totals from the previous night's show. There was a light tap on the office door. "Come in" he said, not looking up from his papers. The door opened and he looked up. There were his two most beautiful wives, Jelena and Gill. His cock was instantly erect. Both girls stood up against the door frame, stark naked ... except...

This is a weird one, guys. But that's just what we do around here on this account! Anyway, this is a male solo scene involving extreme cock growth and the alien also ends up fucking himself with his tail. This is your last chance to turn around if that isn't your thing! Thank you and enjoy! ~*~ Flyx's recently-polished horns glinted in the bathroom light....
