Really though she looks like a big'un, I can't tell if those are baggy pants or if she just got some big ass tree trunks for ankles, and I like em thick too, but not fat, and that looks like fat.
if your girl's mom was hot then maybe consider it... but why risk fucking up your relationship with your lady who is gonna have your son just to have sex with a fatty?
but in all realness, dont fuck her unless you absoluty hate your BM. but think it over. sleep on it. if you wake up and she still makes you feel like punching babies(wassup rising_tied) then pork the porker
