muscle sex

Anal sex with a large bodybuilder where he preferrably bottoms.

I had the sweetest muscle sex with Mr. Olympia just now. His 20-inch arms pushed me deeper into his hole to stroke his sphincter and pleasure his prostate. His glutes throbbed against my cock as he came after I fucked his muscle ass right nice!

sex muscles

The curves of well-defined abdominal muscles that start at the lateral iliac crests and end medially at the pubic tubercle. They form the "V" that outlines a 6-pack. They are referred to as such both because they can be worked out during sexual activity, and possession of such musculature makes you want to have sex with that person.

Did you see his sex muscles when he took his shirt off? I think i just peed my pants a little.

Me: Did you see the size of his biceps? That's hot - his chest too.
Her: Those are some damn fine sex muscles.

musclerexia

A disease carried by a dude who is addicted to "beefing up"; frequently says things like "My arms are SO small", "I need to go to the gym", and "I think I'm gonna do steroids". Psychological impairment causes him to see small, wimpy dude when he looks in the mirror, and constantly self abase. Male version of the common disease anorexia.

Noah's friends became worried when he became socially withdrawn and spent all his time lifting weights. They thought about staging an intervention for Musclerexia
