Grandpa's Dirty House Slipper

Grandpa's Dirty House Slipper, in keeping with the definition of House Slipper, is the act of an elderly male homeowner engaging in unprotected anal sex with a male residential services provider, i.e., home health aid, lawn care worker, maid, plumber, cable guy, in exchange for the worker to provide free or extra services.

Howard needed his lawn mowed and the shrubs trimmed around his yard. However, his social security check only stretched so far and he could not afford to pay for those services. Therefore, Howard availed himself to sex and performed a Grandpa's Dirty House Slipper with a young male lawn care worker mowing the yard of his neighbor's home. Howard ended up with neatest yard and the best groomed shrubs in the whole community.
