v. When the male sticks his penis directly into a girls "cleavage" aiming the head of his penis at the crack inbetween the girls nipples and fucks her tits.
"Dude!?, I Cleavagefucked my girlfriend hardcore last night down deep inbetween her cleavage while she was wearing her bra and very low cut tanktop and had a massive cumshot that ended up all over the top of her tits and both her bra and tanktop."
