A BJ sike
You think you're getting a BJ, but it was just someone moving their head near your crotch because they're dumb or lazy.
I thought I was getting head, but she was just trying to grab my keys like a moron.
He moved his face close to my junk like he was going to kiss it, but he was just tired.
I thought she was going to blow me, but she was just looking for her phone.
