I slid on some fishnet stockings and my new high heels and began loading sissy instruction videos on my laptop.I came across the perfect one, a woman ...alled mistress Minxie who was also wearing stockings and high heels. She had a laptop with a slideshow of huge cocks. She began by telling me to stare at the screen. I felt so sexy watching myself in the mirror dressed like a slut, following her every direction.She then ordered me to dress like a girl and I felt a shiver as I slipped on a sexy. Tracy noticed that he never stopped looking at his penis going in and out of his sister. Even when she said to him, “That feels good.”He replied, “I know,” and just kept watching himself slide into her.Tracy was surprised to see Cassie start playing with her clit as her brother fucked her. “They have definitely done this before,” Tracy thought as she raised her t-shirt and began rubbing her own clit.It wasn’t to much longer before Chris started to grunt and Tracy knew he was about to cum. She. Even as weird as the situation was, that sight and her aggressiveness were definitely turning him on and he started getting hard in spite of himself."Don't make love to me," she growled back over her shoulder. "Fuck me! Fuck me hard. I need you in me and I need you taking me hard!"Fumbling with the lacings on his trousers Nil could hardly take his eyes off her incredibly long legs and shapely ass.

I got another 3 steps maybe and had to stop, it was ticklish it was so sensitive, and because I could feel the start of another orgasm. They asked why I stopped and I said.
