My favorite position in the presence of a shemale is that she is positioned above our tight back to us: it is the only position where we feel three sensations at the same time; the penis inside our body, the partner's weight on our body and, its heat which passes through us through the very compact contact of our two bodies.
It'd be cool to set up a camera like this and project it on the wall of front of me so I could see that big beautiful she-cock jerk off using my asshole as our balls are flopping
