You fuck someone (male or female) in the ass while eating waffles off their back.

Get the The Breakfast Fuck mug.
When you stay the night with a member of the opposite sex, or the same sex if you swing that way, and you don't intend to have sex with them. But in the morning, you decide that you're going to have sex with them.
I went to her house last night, and wanted to get down but we decided not to. But I ended up staying the night, and then we had a breakfast fuck.
