They are friendly aliens, and help to protect our planet, we are at peace with them. But the problem is that Xzionians are..." she searched for the ri...ht words, "Larger than male humans." she said. I understood what she meant."Their laws make it illegal for Xzonian males to have intercourse with females until they are, what humans would call, married. So they must use the male sex workers in the clinic." that answered my first question. "Umm..." I started, "How big are Xzonians?" i. "You are so special to me. This is the best sex I've ever had,” Matt whispered in my ear. It did make me feel special to know that I was able to give him pleasure, especially since I'm sure he's fucked plenty of girls before. Matt was stroking this ass so damn good until we heard a car pull into the driveway. It was only one o’clock in the afternoon, so mom and Uncle Paul should be at work. We scrambled to put on our clothing and see who was in the driveway. Damn, it was uncle Paul. Thank God. I noticed that she wasn't planning to let go of it, so I just shrugged, walked up to her and let her wrap my body in the towel.While she was drying my body, I noticed that she was smiling. I was surprised by myself, that I let her do this. I was sure that had it been a few hours earlier, I would have been blushing from head to toe by now. Sure, I still felt a little glow on my cheeks, but I didn't feel as bad as I would have before. And the best of all, I felt good with her drying my body like. "God, this is really turning me on." She said. "Yep, I am going to go home and rub one out for sure." I said. "We could do that together." she said as a kind of suggestion/question. I looked at her and said no problem. 9 came and we closed up in record time. I lived close enough to walk and so we went there. We got in the front door and she was taking off her top already. I said I was going to get more comfortable and I would be right back. I went into my room and took off my cloths and put on.
