I was feeling particularly horny one time so started masturbating in my bedroom. I saw one of my neighbours at his window so I playfully left my curtains open so he could get a view. That got me really excited and I was well on my way to cumming when he suddenly appeared at my window. He had invited himself over for a closer look. He climbed in catching me totally naked. I agreed to give him a hand-job if he left after that but he had other ideas. He started finger-fucking me as I rubbed him which got me so wet and worked up that I ended up begging him to fuck me. When he finished he squirted his full load of cum in me
