When you are in a swimming pool, you go behind a woman and start to jack off. You then shoot your load and aim for her back, when she turns round you just say it was a water splash and swim off.
Man: *jacking off behind woman*, dick erects and load gets shot
Woman: WHAT THE F!!! something splashed on my back
Man: Oh its nothing its just water. (HA thats was a good seman suprise!!!)
