New pervert grandpa neighbor

He was a bald grey haired grandpa in his late 70s with a big belly and I wanted to have sex with him so bad. Never have I had sex with a grandpa so I thought that'd be exciting
After meeting too often at the stairs I started to think he was stalking me...and that was true. So one day I wore a tight top wich was showing my boobs a little bit too much,went down the stairs and when I got to the road...i saw him looking at my boobs from the 6th floor
This went on for a couple of months until one day he knocked at my door to ask me for some help with his computer. I opened the door wearing booty shorts and a tank top with no bra. As soon as I saw him my nipples became really hard and started to poke through my top. I agreed immediately to help him and let him take me to his place. While he was guiding me there I could feel he was staring at me from behind and I was loving that feeling. My pussy started to wetten around my cameltoe. I was so aroused I wanted to jump on him at that moment. He took me to his bedroom where he had his computer. I sat myself on the rotating chair and started to learn him the basics. I could tell he wasn't concentrated. The whole time he was looking at my boobs from where I was sitting. And the only thing I was thinking about was his erection
He then remembered and said:ohh I'm such impolite I didn't offer you a drink. Although I refused couple of times he went to the kitchen making me some coffee. I took advantage while he was making me coffee to look over his browser history. That old grandpa didn't know how to operate a computer but he sure knew how to search for porn. His history was filled with big boobed teens getting fucked by really old grandpas. I got so wet I thought I came all over the rotating chair. I opened one of the videos,muted it and started watching it while moving back and forth on the chair to stimulate my clit
I had one eye on the computer and the other eye on the door fearing he would appear from time to time. That girl was really getting that grandpa dick in all of her holes while her boobs were bouncing up and down. All of a sudden I saw that grandpa knocking on the door asking me with a smirk if he was disturbing me. I didn't know what to answer. He gave me the coffee and I started taking big sips. Greedy girl-he said to me-you are really swallowing that coffee...pointing out his sexual innuendo. I drank it so fast it burnt my tongue. I had to excuse him to get back to my place but he asked me for my email in case he would need some more"extra classes of IT". I couldn't say no so I gave him my adress and left. He insisted of taking me to the door. I barely said goodbye and he gave me a slap on my ass. It took me so by surprise of his guts to do that. Later that night I checked my email and saw that he had sent me a couple of old and young videos. He was asking for my opinion (yeah right). I watched all of them while touching myself and cumming like crazy
After that day I always used to bump into him on the stairs and everytime he did something sexual...one day he flashed his dick to me,the other day he greeted,blocked my way,looked to the other directions and when he saw there was no one opened my shirt and took out my tits to give them a suck. He was sucking them so good. I noticed there was missing some teeth in his mouth and that excited me even more. I was caressing his fat bald head while he was sucking and biting my tits. Then he laid back and told me that he'd love to do so much more with my body but he had to go....
After some days of sending me porn he suddenly stopped. Until one day I got an email that said to meet him at his place to see some really explicit porn. I was tempted by the idea until one day I decided to go at his place. His game was to make me addicted to his porn and then to ask me to come around
After school I went to him. He said hi like nothing had ever happened. Cut straight to the chase invited me to his bedroom and sat me in front of his computer. That day we saw multiple videos. He had some good porn. Some of them were with payment methods. He was paying to gain access to the old and young sites. He opened a video which showed a teen being gangbanged,used and abused by old men. He asked me if I liked it and I said yes. We both started touching ourselves then touching each other. His cock was so thick and his balls were hanging low. I could tell they were full of cum but I didn't want to give him a bj right away so he came on my lap and made me lick it. His sperm was thick and I swallowed it. After finishing what we were doing I asked to leave. He accompanied me to the door as always and opened it. Then grabbed my head and started kissing me. His kiss included a lot of suction and tongue. He was a greedy old man. I had his saliva all over my lips and I couldn't get away from him. I was trapped in his arms,rubbed against his big belly and still could feel his erection. Suddenly he heard a laugh behind my back. It was another old man that lived in the same building. He told my grandpa:lucky you that you found a young teeny to fuck but would you mind sharing her? And gave me a wink. He answered:after she is mine she can decide if she can take two or more if she wants. And the other replied:she for sure can take a bunch of us(reminded us the nipple sucking scene that he was aparently watching it from his door eye)...and left telling me he was hoping to meet again
