no lie this happened to me as well, but 2 of them. One was not fat, but I SURELY would not have fucked with her.
the other one was a whale.... but had MASSIVE tits, like WAY massive.
we were all going camping in the morning so they were gonna crash at my pad, & this was my homeboys baby momma & his younger sister... I got really drunk, woke up to a BJ from the both at like 2am, & they were both drunk too.
but why the big girl climbed aboard like she had the green light I dunno.... I mean, ya, I was getting a BJ from 2 chicks so physically it was possible, but I had to tell her to get off me & go back to what they were doin' LOL
TL;dr but shitty part was I was trying to get at their friend, & when we got back, they both went n told the fine chick I was getting at & fucked it all off for me.
