I know that a lot of trannies cannot cum from blowjobs or handjobs, but I wish more would try. This scene is an example of that. The tranny getting sucked off should have let her girlfriend suck her or jack her off to completion. Kind of like in male/female porn when a guy has a long fuck session with a hot girl, then at the end he jacks himself off to cum instead of letting the girl jack him off. Drives me nuts.
