You'd be surprised some of them big ass titties are lightweight. I fucked with a chick with big titties and them shits weighed nothing. I was shocked! On the other hand, my ex-wife had some big titties and the first time I got my hands on them, she was on top of me when I undid her bra. Them shits fell and hit me on my chest they were heavy as fuck! I wanna say damn near 10lbs each. I asked her how the fuck she deal with all that weight!! She wears a bra that keeps them really close to her chest so she don't topple over from the weight!!
