I had never been abused by an 18-year old boy in this way.As I continued to allow him to ram his cock deep into my throat, my gagging got worse until ... felt him stiffen and them with an almighty thrust he pushed my head hard down and buried his cock deep into my throat. I could feel his pubic hair smother my face as I gagged then a bellow as he unloaded what felt like pints of sperm down my throat. With each spurt of cum I gagged even more. Cum was dribbling down my chin, it was all over Matt's. And then there I saw him for the first time. We both just kept looking at each other for few minutes. No one tried to initiate any conversation at first. The grin on his face was evident and I also couldn’t stop blushing. Then I just said hi to which he replied with a smile. I climbed on his bike. The first touch of ours while sitting on his bike sent sensations deep down to my body.We didn’t talk much till our way back to home as we both were nervous. We reached home he opened the door and let. Master K looked at the clock, "fifty strokes", he stated calmly. "Nick, what are you going to use tonight if you win"? "I'd like to use that new fiber rod I got but it leaves some hellacious marks, you ok with that"? It's pretty much up to her at this point", replied K, "she knows what the rules are". "She came to me because she was fascinated with the chain flogger", K grinned, "So I think that will be the correct choice for me to use on her". Even knowing it was a mind game they were. He removes my hands and pins them to each side of my head. He’s holding my hands down while his cock nestles between my breasts. Then he starts to move his hips back and forth, his cock moving back and forth between my precious tits. He’s found a rhythm that he’s enjoying. I watch in horror as more pre-cum gets painted onto the top of my chest and between my breasts on his strokes, coating me with his man-made lubrication. His cock continues to get closer and closer to my face as he gets more.
