However keep in mind that when she whispers or yells the words suck my tranny cock. You can do the same right back to her. Make her suck your cock as well. In fact most trans girls love a hot 69. Each sucking cock and getting theirs sucked as well. Just ask any trans girl and see for yourself. She will jump at the chance for a 69.
Now that you are reading this and looking at this amazing photo of Mariana. How would you feel if she looked at you and said. Suck My tranny cock! What would you do? Just look at her amazing hard cock standing up there. Would you grab it with your hands? Or down down and slip it right into your mouth. Maybe you wold even want to squat down on top of that amazing cock and ride it for as long as you could take that pleasureful pain.
