This is just beautiful. I love the guys hand on her head. She's finally starting to realize that she's a real cocksucker! That she was once a male, makes it so much hotter :P
Wow...just.....WOW. Incredibly beautiful and erotic...I've imagined myself transformed into a girl and going through that same experience. The first time...the taste and texture...the moment of shock when he climaxes...and the conflicting feelings of shame and lust afterward.
That facial expression in the final frame looks to me like their trance just broke (and hard), leaving them to realize that they just sucked a cock and swallowed its load -- and enjoyed it
