Rapid firing my chores like the previous day, but intentionally dragging the last one out long enough to be past noon, I headed to the corner. This time the older teen was already sitting on his porch and as I approached the corner, He said, "missed them again." I play like I was disappointed and said, "damn." He didn't hesitate to say, "come on in." With a hop in my step I bounced over to his house to go inside. Something deep inside me had changed and I was aware of this change, but didn't know what had changed or why. I just knew that today I didn't want to wait to touch his cock and lick it. We barely got to his basement when I sat on the couch, waited for him to sit down, and said, "do you want me to lick your dick again?" I barely finished my sentence before his shorts were off and he was sitting. This time I was actually watching as he cock began to grow in anticipation of what was ahead. I never saw him actually get hard before. He was always rock hard from the magazines, but this time he was growing before my eyes. I grabbed him and began licking his cock. His reactions were even more arousing for me this time. He was really enjoying this, as was I. He was now about to introduce me to something even more intense. He said, "put my dick in your mouth and suck it." He said it so matter-of-factly. He didn't ask me too like he did of previos things. He just said do it. I didn't question his request either. I stopped licking and opened my mouth and guided his cock past my lips and into my mouth without hesitation. His immediate reaction, breathing, and stiffining of his legs made it clear to me that this moment was significant in my life even if I wasn't aware of why or how. All I knew was the moment his cock filled my mouth, I was coming to his house as often as I could. I knew I was going to be in this situation often and I was fucking excited by the thought. I was so into the moment, I was enjoying what I was doing so much, that I didn't expect what was about to happened. I heard him make a loud grunt, his thighs tightened, his legs extended, and I could hear his clinched teeth supressing a "guh" sound right before this unexpected, warm unknown substance hit the back of my mouth. I threw my head back, my mouth and jaw hanging open with some unknown substance leaking from it and with a gag I asked "what the hell is that?" He grabbed his cock and jerked real fast unable to speak before finally saying, "my nut." "Your nut?????" "What the fuck is your nut?" He said you made me cum. What in the world is he talking about? I never had anything like this come from me so why was it coming from him? Well, he educated me once again to the thrills and spills of a mature male body and what it can do. I thought that shit was nasty whatever it was. At least, NOW, I knew what it was. Before leaving to head home I asked, " can I come over tomorrow?" He eagerly replied, "hell yes. you gonna suck my dick again?" I fely proud to say, "of course I am." I slept much better that night!
