Purple headed yogurt slinger

A penis

An erect penis

Basically when your penis is hard and erect it's head will be purple, hence 'purple headed'

The 'yogurt slinger' comes into play when the penis gets so sexually stimulated it spurts out a yogurt like substance, aka ejaculation

The man rubbed his cock for so long it slung its yogurt from its purple head

Then his roommate walked in

His roommate began sucking his cock, making him cum again

He began to softly moan

His roommate continued sucking

Soon the roommate started undressing themselves

The two got out some lube and they continued pleasuring the man's purple headed yogurt slinger by shoving it hard and fast deep into the man's roommates ass
Both vocalized their pleasure by moaning

'No homo', ofc :)
