I was out in the garden on a hot sunny morning sunbathing nude on a lounger, both neighbours were out of the houses next door so I was sure no one was watching me get my all over tan. As it got warmer I decided to stretch out flat on a towel to get an even tan, I was on my back massaging some sun lotion on my legs and groin and my cock started to stiffen.
Not neglecting my more sensitive parts I began to rub lotion around my now fully erect cock. I slowly massaged plenty of lotion in and was enjoying this so much that I began to stroke faster and faster making slapping sounds as I jerked myself off. I became excited by the fact that I was going to make myself cum outside for the first time. I was starting to moan out loudly as I felt myself about to explode and didn't notice my next door neighbour arrive and open her bedroom windows.
I was oblivious to her but in full view of her wanking myself off and spraying my legs and stomach with cum as I reached an intense, powerful orgasm. I groaned with delight as I kept jerking my cock as more cum spurted out, then got up to wipe myself down when I noticed her windows were open and realised I must have given her quite a show!
I returned outside to sunbathe nude in full view of her bedroom window hoping she could see me lying there with my 8' cock standing proud and stiff with excitement pretending that I did not know she was back home. I never saw her that day but every time I see her now she smiles and has a glint in her eye when she says 'good morning'
