She changed nipples and continued to fuck him. Then without any warning she turned around into the reverse cowgirl position and rode him like a jockey... trying to win a big race.Jake had never been with a sexually active woman before. His wife would never have sucked his cock or gotten on top. He looked right straight ahead at Beverly’s tightly puckered asshole and poked at it with his finger.Beverly purred then turned and said, “Go ahead. Poke it all you want too. I’ll let you fuck it if you. .." Kristen sighed."Um, well ok then." The young man was still blushing as he turned to go."Wait!" Kristen said, and she reached out to grab his arm.

The young man was confused as the beautiful girl sank to her knees right in front of his groin, he could see pretty much straight down her blouse now and. It's a lot like slavery."Chastity giggled for a moment before coughing in pain. "Like? I'd say that the description makes it pretty much a form of slavery for the concubines.

So I kept watching and I fell deeper and deeper into the sissy world, becoming more feminine and more submissive, I forced myself to watch solo male videos while jerking off and I learnt to love cock, soon I was able to cum watching gay porn, which was quite an accomplishment for me. It altered my perception, I started picturing myself as the girl in every video, sometimes without me even noticing it. I fell into the sissy mindset, I started reading sissy blogs, doing sissy tasks and watching.
