College project surprise

I blushed and felt my cock swell with excitement. I knew that the best was yet to come.
Somehow we were able to compose ourselves enough to finish the school project. It took about twice as long as normal because neither of us could focus on anything other than what had just transpired. After we finished I grabbed my things and went home for the night. I had one of the best nights of sleep I think I’ve ever had. The next day I walked with Laura to class. She couldn’t believe that I didn’t know she was transsexual. I mean, sure, she was 6’3” and built like a linebacker. But she had a pretty face, beautiful feminine curves and a soft voice. She told me about her roommate and informed me that she was also trans. Long story short, Laura told me that she told her roommate about our fuck sesh and that she wanted to join.
“Would you be open to that?” Laura asked. “It’s okay if not. We just always like to share boys”
“Of course she can join,” I replied, barely able to contain my excitement.
“Just do you know, she can be a little more dominant and kinky. Hope you have an open mind”, Laura warmed me.
“I like dominant and kinky”, I said with a wink.
“Good, you’re gonna be in heaven”.
That night I walked back to Laura’s. I couldn’t believe I was going back for round 2. Not only that, but another dick to please. When I arrived I knocked on the door.
“Come in”, I heard.
As I walked in Laura was sitting naked on the couch with a beer in one hand and her hard cock in the other.
“Danielle, john’s here” she yelled upstairs.
I looked at the staircase, and down came another gorgeous girl. Danielle was smaller than Laura, about 6’. Smooth black skin, a little chubby but not fat and had long braided blonde dyed hair. She didn’t have a shirt on, just a small g string where I could see a huge panty bulge. She smiled and introduced herself. I went to shake her hand, but instead she pulled me in for a kiss. We made out for a couple seconds, when all of the sudden, she forcefully pushed me down to my knees and pulled her sick out from the little bit of fabric that was concealing it. She shoved her already hard cock straight into my mouth, grabbed the hair on the back of my head, and started to face fuck me.
