Spotted My Neighbor

At my home, our backyard yard is fenced in. The back length of the fence is shared with our neighbor with a pool. There’s a picket that has a natural piece missing from it where one side could look see to the others pool. Both my parents travel for work, so I watch over my their home. I live in the apartment above the garage. I have just started working from home so the arrangement works out even better. I’ve never been an inside kind of person, so I generally work outside as much as possible. My neighbor that we share a fence with is in his 30s, his wife looks like she’s in her early 20s if that and an aspiring Instagram model. I don’t know how they ended up together, they’re polar opposites. Sometimes when she’s in town I like to take a look or two through the fence at her great body. The other day however I heard some moaning and grunting from the neighbors so I went to look through the fence. There he was, sitting near the pool, watching gay porn, with testicle weights on, a dildo in his ass stroking his unnaturally giant cock. I was in disbelief and just blurted out “whoa!” Of which he heard. I was completely turned on by what he was doing. He heard me, at first looked concern and then I know for sure he looked at that exact spot on the fence!
He smiled.
He hollared over and asked if I want to come over. I said sure, to which he told me to meet him at the front door. I came over, nervous and excited. He invited me in, still naked with an erection and balls dangling low. Close the door, and asked if I had liked what I had seen. I did, said I would mind seeing more. He asked if I wanted to join him, my cock was obviously hard through my shorts. I said yes please.
He hit his knees pulling my shorts down and began giving me the best head I had ever had in my life. He asked me to fuck him, and hard, I agreed and he bent over the dining table and I pushed my cock into his ass and went wild. I was getting close to cumming and he told me not to pull out, so I let him have it all. He wasn’t done and said it was my turn, I wasn’t nearly reading to take his massive dong but he was nice enough to lube up my asshole. He pushed into me, and I let out a slight yell of pain, he assured me it would be okay. I swear he tore me with his thick cock. He began working my ass like it was our last day, he had so much stamina. I was dick drunk. This was the best ass fucking ever. It was so large and hard, and he could really work it. I eventually got weak and ended up on all four. Ever stroke he had me dripping cum and before I knew it had had climaxes without any penis stimulation and came all over his floor. He eventually let loose his flood of cum in my ass and sent me on my way. He said we will make this a regular thing ass he grabbed my ass and kissed me on the head. He told me to hold the cum in my ass aslong as I could and to let my ass heal for next time. He owns my ass now and I love it.
