When I went through second puberty, my bi girlfriend didn't break up with me. Instead she gave me a dildo to get ready for her strap-on. I filmed my practice but somehow sent it to my roommate. He said I was ready for the real thing. He helped me prove it & film a much better video of my progress.
My girlfriend's libido had been gone for a while due to some meds, so she gave me a single hall pass to use on our boys' trip. What bad luck to then be slipped an X-Change & become the exact kind of girl I wanted to fuck. But my friends were there to make sure that hall pass was used. Thoroughly.
"I don't remember her being so thicc," your friend said after swapping with your step-sister in swap class. The hormones kicked in quick, making her increasingly horny & sexy, a dangerous combination. Could you endure the daily updates on her growing tits & the sound of her moans through the wall?
