The blind postman

A sexual act usually performed but not limited to a male and female.

Initially the male is blindfolded and then undressed by the female.

The female then undresses and lays legs akimbo on the edge of a piece of furniture, usually a bed or couch.

The blindfolded male then proceeds to find the females "letterbox" so he can insert his "package" into it.

As the man finishes he yells out "your package has been fully delivered"

"I'm looking for a blindfold can you help me"?

Store clerk: " what do you need a blindfold for?"

"My girlfriend and I are planning to do some roleplay later on and she suggested we try "The blind postman".
