Matt’s body became very ridged and I felt his dick get very stiff and start throbbing, and missionary I felt the welcome pulsing knowing a man was filling me with his seed. I just about orgasmed from the pulsing. Matt breathing slowed down, and then he withdrew his wonderful dick. I laid there, with the cool air on my body, and nude. Matt left the room and I took my sleep mask off. I big cock sat up and was at a loss for words what I saw. I could see all the semen which was oozing out of me. How could such a young man have that much in him. I was so totally turned on and had no idea what to think, what to do, or even how to behave. For reasons I will never understand, using my finger I fished out as much cum as I could from my vagina and ate all I could. I loved the smell and taste of his semen. I laid back on my bed, legs slightly open, and wonder what I had just done. My sister’s boy just fucked me and left his semen in me. I was excited, but very nervous if he ever told anyone. My mind was stuck in a loop of remembering what it felt like to have him on me and cum in me without ever really thrusting into me. How a young man can be so excited that he cums from just being in a woman is exciting to me. I got up the next morning and could still feel the crusty feeling of dried semen on my vagina. I have so many mixed thoughts on what I had just done. The next afternoon I japanese took off work early so Matt and I could go out boating with the neighbors. We all had a great time and was just enjoying the ocean. I could not help to look at Matt and see he was just a boy who was trying to figure out life. He was cute, there is no doubt about that, but he would be a good catch for some high school girl. About 9:30 we had gotten settled back in and were just hanging out. Matt then asked, “Aunt Kim, can I ask you a few personal questions?” “Sure, what ever you want.” I said with a smile. “Well, do girls, I mean. Dang.” There was a pause. “Do girls really like oral sex, on a guy? On my videos they seem to really enjoy it, and act like they love Hardcore to swallow.” “Well I guess it depends on the asian girl. I know many that really enjoy it, they feel like they are in charge. I know I do. And as far as swallowing. There’s not really any other thing to do at that point if the guys starts to cum in your mouth.” “Ok, cool, thanks.” Matt said and turned a little red and then said, “Well, good night.” Matt then got up and went down stairs. Three days went by and we just went about enjoying the summer. I was so horny but never wanted to be the one who instigated anything. The next Saturday afternoon Matt came up from down stairs and handed me a note and turn and walked fast back down stairs. Kim flinched like she was touched by a live wire. She moved up to Chloe's side then put her mouth close to her ear missionary and whispered something to her. I was unable to move, Hardcore think, or apparently breath. But he continued to remain silent. Now, I'm either going to wash your back or play with your pussy. I grimaced and whirled around. “What are you doing.” What is going on.” As she moved, she pulled the covers off of me. "Now, Matty, here's the thing... My body – I can still remember it clearly – took over control from what remained of my conscious will. I believe you if you say I'm not dreaming, but that ," she pointed at Lilith, "is a real demon, and you called her your mistress? I knew the asian feeling wouldn’t last though as my little body would collapse from exhaustion very soon. If I didn't extract myself soon, I might tear her trying japanese to get out later and we big cock had been very lucky so far. It has another name that you have probably heard of.
