Surrender to your superiors!

I don't usually write things like this, but wow, I still can't believe what happened last night! I'm a 35 year old dominant man and last night I met a very cute and passable 20 year old trans girl and her 18 year old Mistress! I found Asya on grindr a few nights before and we really hit it off! I told her I would love to meet her and her Mistress was welcome to join and watch or participate. Asya has only been dressing for a year, but with her Mistresses help, she has already progressed her look far beyond most girls I've met, but her experience and training are still lacking. We decided to meet for dinner before heading back to my place, Asya was nervous but I told her I'm really only into girls, so she came to dinner dressed and looking stunning! I pulled into the parking lot just as they were getting out of their car and there they were, 2 super cute little goth girls, I wanted to skip dinner and take them home right then and there! This was her first time going out dressed and also her first time meeting or being with a Man! I could tell she was both nervous and excited to meet me and I think having her Mistress there to support and encourage her made all the difference in her comfort level. After dinner we went back to my place. The Mistress just wanted to watch, so she relaxed and puffed her vape while I had my fun! I wanted her to have some involvement, so put a remote vibrating plug in Asya and handed her Mistress the controls! I could tell they both enjoyed that a lot! While her Mistress played with the remote I teased, groped, kissed, choked, slapped and spanked Asya before telling her to get on her knees and taste her first real cock! She couldn't control her excitement! She eagerly pulled my cock out and started sucking, she couldn't take it very deep and she needs a lot of practice, but I'll teach her! For the disappointing blow job I thought she deserved a spanking... she told me before she likes being spanked, but her usual spanker (Mistress) is only about 90 lbs, I'm 240! Idk if she was ready for such a firm hand! But she took it like a good girl and her mistress was very amused as well! After her ass was a nice shade of red it was time for the moment she had really been waiting for... time to get fucked for the first time! Her mistress has pegged her, but their strap on is 2 inches shorter and a lot thinner than I am! Starting gentle and getting rougher as we went, multiple positions, taking my time, before long she was pushing back into me and bouncing on my cock like a good little slut! Her Mistress sat there puffing her vape, watching with a big amused smile as I fucked the shit out of her little slut! It was so hot looking over at this cute petite little 18 year old mistress watching me destroy the sissy she use to call boyfriend! I fulfilled a huge fantasy last night! I'm about 90% sure I'll see Asya again, but I really hope her Mistress wants to become more involved and possibly cuck Asya with me! Dream come true!
