Lucky Little Slut

Last weekend I wrote to my beautiful TS sister Roxanne to see if she wanted to play. We had done some group sex play a couple of weeks earlier and I was anxious to take it to the next level. She was as excited as I was to get the chance to play again. When she arrived we went to my in-home theatre and put on some straight porn to get in the mood for sex. We did some making out, and some grinding. I sucked on Roxanne's tits for a while because like me she really loves that; we both can orgasm just from having our breasts sucked.
Roxanne lifted my miniskirt, pulled my panties down a little, and began playing with my clit. I explained how rare it was for me to get a sissygasm but that just challenged her and she just worked harder. As I lay back to let her play we began to discuss the kinds of men we like and found our tastes almost identical.
It seems a bit odd that in everything I had mentioned the subject of black men never came up. Roxanne just blurted out "Do you like BBC?". I asked "Haven't you seen any of my videos on Ashemaletube?"; she answered "No". I told her about the BBC videos I had made and said "Let's invite some. Roxanne's determination to get a reaction from my clit was rewarded with a minor surge of fluid.
As our conversation progressed Roxanne explained that she wanted to be a slut like me and that she really had little experience so far. This shocked me because I had assumed that because she was a TS and on hormones, she would be quite experienced. We each hit our favorite websites and apps to see what kind of trouble we could get into. Our efforts were rewarded when a beautiful black man with a 9 1/2" cock agreed to come and fuck both of us. He brought some party favors and made good on his promise by switching back and forth between us girls. He started with me and after fucking for about 15 minutes I asked "Wouldn't you like some of that?", and gestured toward Roxanne.
I watched him fuck Roxanne to drink in the visual beauty of sex.
