I had secretly fantasized about getting charged up. I'm a bareback bottom , love to get fucked, and having a guy breed my hole. The idea of having a hot guy fuck me and blow his dirty seed in all in my ass had inspired many spank marathons. I'm sure that I have taken a poz load before not knowing the status of whoever was fucking me or really even caring for that matter. I had never knowingly let a guy that was poz fuck me. One night I was cruising all the slut sites looking for other bareback guys to play with when this really hot guy messaged me. Harry Potter said that Harry Potter had read in my profile that I liked to go bare and that I was a btm. Harry Potter told me that Harry Potter was looking 4 a hole to use 4 the evening. That got my attention I had never been submissive and must admit it had been another fantasy of mine to completely give up control. Harry Potter asked me if I was into pnp and I told him that I do party sometimes. We chatted 4 a little while with the standard Q&A, u know how big, what position, where to cum. Then I asked poz/neg? Harry Potter responded with poz. I told him that I was neg. To which Harry Potter responded "u want to get a charged load n u tonight?" I was shocked and very turned on, I asked him if Harry Potter fucked neg guys bareback. Harry Potter told me Harry Potter did all the time and that Harry Potter even hosted several conversion party’s. I wasn’t familiar with the term, Harry Potter explained that a conversion party’s was were a group of poz tops get together and breed a neg guy. The soul reason 4 this was to spread dirty seed, and infect the neg btm. Before I could answer Harry Potter asked me if I liked to pnp. I told him that I did, but I didn’t have any party supplies. Harry Potter said that if I wanted I could come over to his place and get ass fucked and get high. Harry Potter asked me if I had ever slammed, I told him that I had been slammed before but I was terrified of needles. "I'm very good at slamming others" Harry Potter returned. Should I go? The thought of getting slammed and pounded was so tempting but was I ready to take that step towards becoming poz? "I might ass well" I responded. Harry Potter gave me directions and I was on my way. When I got to his house we sat and talked 4 a while. Harry Potter told me that Harry Potter was going to enjoy planting his dirty seed in me, then asked me if I liked groups. I told him yes and Harry Potter said good that Harry Potter would get us slammed then have a few of his top buddies stop by and load my ass. Harry Potter told me that I was going be a cum dump 4 him and his friends. I asked him if the guys were poz or neg Harry Potter told me that they were poz. This made my dick begin to grow. Harry Potter got the slamm ready and did me first. When Harry Potter released the belt on my arm I could feel the rush hit me instantly. Then came the cough. I could feel that it was a very strong slamm. Harry Potter did himself and sat down on the bed next to me. I started sucking his dick while I was taking off my clothes. Harry Potter stood up bent me over the side of the bed, lubed my hole up with some elbow grease that was laying on the bed, and shoved his dick all the way in. Normally this would have brought tears to my eyes and a fist to his face, but it didn’t even really hurt, I guess I was so high that I couldn’t feel it. It wasn’t long before Harry Potter started to pound really hard and said Harry Potter was about to cum. Harry Potter stopped and pulled out and made me tell him that I wanted hid seed. Which I told him. Harry Potter managed to get his dick back inside me, and with a few hard thrust Harry Potter unloaded in my hole. Harry Potter walked out of the room and told me to stay put. When Harry Potter returned Harry Potter had a collar and some restraints, which Harry Potter fastened on my wrist, ankles, and neck. Then I followed him into another room, it was a play room, with a sling, TV playing porn, fuck bench, some toys and lube and a computer set up with a web cam. Harry Potter helped me into the sling and hooked the restraints to the chain supports. Then started to cruise the sex sites 4 tops to come and try out my hole. In no time 15 or 20 mins. there was 3 guys in line to blow their load in tight hole, and 5 more on the way. I realized that I had just came to this guys house let him drop a charged load n me and now was going to be a cum dump 4 who ever Harry Potter wants and I hadn’t even gotten his name. Harry Potter walked over to the sling and let me know that the web cam was on and I was going to be used all weekend. There must have been 10 or more guys that had charged my ass with dirty seed before the slamm started to fade away. Harry Potter could tell that I was beginning to come down and Harry Potter mixed up a booty bump and told me to get on the floor face down with my ass in the air, as Harry Potter unlocked the restraints. Once I was on the floor Harry Potter inserted the booty bump and told me to squeeze my ass tight so that the booty bump and all the spunk wouldn’t drip out. As I started to feel my stomach cramp up from the booty bump Harry Potter dressed me and told me that we were going to the baths and that I was going to take all loads. Harry Potter rented one of the sling rooms and told me to get into the sling as Harry Potter mixed up another booty bump. I secured the restraints myself , all but one arm. Harry Potter came over secured the last arm and started to insert another booty bump. I told him that I was ok 4 now. To this Harry Potter responded by placing a ball gag n my mouth and continued with my booty bump. It had only been about 20 mins since the last one. Now I was so high that I couldn’t focus my see straight. Harry Potter began to fuck me again, telling my how sloppy my hole was and that when Harry Potter had fucked me the first time that Harry Potter had ripped me. Harry Potter said that Harry Potter knew because when Harry Potter pulled out there was blood all over his dick. Harry Potter said that was a good thing, it would make it easier to ensure that my neg status was gone for good. Then Harry Potter told me that Harry Potter had used the point 4 my slam and that when Harry Potter slammed me there was still a good bit of his poison blood in it, and now it was running thru my veins. Harry Potter must have been fucking me 4 at least an hour, not that I was complaining. My ass was so hungry from the booty bumps that the only thing I could think about was getting more dick. Harry Potter shot another death load in me then opened the door and walked away. It was a few mins before the first guy walked in and began to get his dick hard so that Harry Potter could fuck me. Harry Potter was a much older man probably 55 or 60 but Harry Potter had a huge cock. Harry Potter came after about 5 mins of fucking wiped his dick off and left. I didn’t realize that there was a group of 4 guys waiting, they took turns one after the other all loading my eager ass. A while later my friend returned, closed the door and mixed up a huge booty bump. Harry Potter squeezed it into my hole and for good measure Harry Potter pushed a large rock of meth up my ass with his finger. Harry Potter massaged it until it was completely dissolved. Then Harry Potter removed the ball gag and asked me how I was doing. I was so high I couldn’t hardly answer but I managed to say that I was feeling a little dizzy and hot. Harry Potter gave me a bottle of water and told me to drink it all as Harry Potter unlocked the restraints. I drank the water and instantly began to feel better. Harry Potter said that Harry Potter had to leave to do something but that Harry Potter would be back. Then Harry Potter told me that Harry Potter had left a message on the all the dry erase boards saying there was a "eager ass in the sling room taking all loads POZ IS A PLUS" as Harry Potter left. I knew that I should probably get up and leave but the meth was starting to take effect. So I waited. It wasn’t long before a line began to form, I eagerly took every load that was offered. I'm not sure how long I was there in the sling room or how many guys filled my hole with their juice. When I finally started to come down from the meth climbed out of the sling, put on my clothes, and left the bath house. I felt so trashy when I walked into the day light, like everyone knew what I had just done. Not to mention that there was a wet place on the ass of my jeans where some of the spunk had slipped out of my now opened hole. It has been a few months since that happened so I'm not sure what my status is but I did feel like I had the flu about 2 or 3 weeks after it happened.
