A
nasty wank is one in which the man is sneakily pleasuring himself, perhaps in a public toilet, in the
car, or in a friends bedroom while they are out. The sneaky
wank works well until it goes wrong, either because the man has not provided enough space to come, or is not prepared for it when it happens.
The result is usually a very
wet t-shirt or other item of clothing, which will be embarrassingly obvious. The sneaky
wank can also be preformed lying down, and may result in come running down the leg and becoming entwined in hair. This is almost impossible to clean up, especially in a hurry. The situation is exacerbated if a friend or relative is about to walk in or actually does.
Can lead to embarrassing situations for all involved.
