There must be something in the water in Sunderland that produces the absolutely worst tits in the country. Some great looking arses but horrible haunting tits

Maybe its the salt in the sea air or maybe its the amount of kids they have or the amount of drugs they do who knows 🤷

mammary suffocation 

Covering of the airways with female (sometimes fat-ass male) breast(s) for an extended period, resulting in Asphyxiation.

A common accident, seen in activities such as motorboating, BDSM, cowgirl stylecoitus and cockboob sandwiches.
As mammary suffocation requires both airways to become immersed and enveloped in plentiful amounts of adipose breast tissue, it usually involves breasts (racks,knockers,bazingas,tig ol bitties, boobies,etc.) of bat-shit epic proportions.

In recent years, popular culture has depicted mammary suffocation in such a way as to emphasize its epicly awesome nature. An unnamed survey reported 9 out of 10 men would give up their left nut, if it meant that their eventual cause of death would be via mammary suffocation.

Bob: "You say that now, but everyone else who's tried ended up dead from mammary suffocation."

Jim: "AWESOME. I'm in."
