63

A sexual position similar to 69. In 63, the girl is on top, and instead of giving the guy head while he eats her out, she lets him titty fuck her. The outline of her boobs is like the number 3.

Girl #1: wow did you 69 him last night?
Girl #2: nah i was feeling a little lazy so we did some 63.

63

My smile has left…
Gone with the numbers …
I am grumpy…
And no longer loving…
My heart no longer feels jumpy…
My face is all squishy…
Ready to grrr at anyone who crosses my path…

Maybe I can drain the grrrs out of me

63/ me
I hate being grumpy, but I can’t find my happy. Maybe that was Oscar the grouch’s issue… he just lost his happy

63

A tricker position than 69.

The guy is standing up while he’s inserted into the girl who is reverse cowgirling and bends her body forward to eat out his ass.

“Damn you need a lot of stamina to 63, I bout dropped my bitch on her head”
