In Season 4 Episode 22 “Sibling Rivalry”, Lois becomes fat after Peter refuses to have sex with her after getting a Vasectomy, but Peter realizes that he loves her fat body when they accidentally have sex, & he starts feeding her more calorific foods like cake to fatten her up more for fat sex.

I’m a freaky fuck who really wants that to happen to me, where my horny husband who is turned on by completely fat BHM x BBW sex, makes me gain a lot of weight so he can use his fat girthy cock to plunge my big fat pussy, & enjoy the weight of my body squeezing every drop of cum into my womb.

We could even include the idea from Season 2 Episode 17 “He’s Too Sexy For His Fat” when Peter after getting liposuction to lose weight accidentally falls into a Vat of Lard at the Lard Factory, uncontrollably swallowing down the lard & gaining all his weight back.

No details held back, double chin, flabby bingo wing arms, thunderthigh cellulite, muffin top with stretchmarks, backtitties, cankles, & folding rolls of flab.

Completely hot & heavy naked sex between two big fatties of the same gender.
