I was feeling particularly horny one time so started playing with myself 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 and watched me before he climbed in. Caught totally naked I agreed to give him a hand-job if he left after that. He had other ideas though and started finger-fucking me as I rubbed him. I got 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
