Rather than a link between cock size and boob size, I was wondering whether there might be a connection between cock size and booty size - where a girl with a big booty might actually need a guy with a big cock - given that all that big round booty flesh might make it impossible for a small guy to "reach".
From experience, I can say there definitely is. In college, I had sex many times with a girl you would consider a BBW; she had supple DD breasts with wide areolas, but her ass was huge. Often times in sex I would slide in and out with ease, feeling the slender length of my cock, around 7" at fullest, making it feel as if she was resized by a bigger cock. Now there is a portion of them that disregard size, but nothing makes me feel more aroused than imagining trying to pound her at her deepest, and not being able to slide as deep because her ass was not only big (estimate 47"), but thick, as she was quite active.
Sometimes, I fantasize about her bottom growing, day by day, eventually not being able to put my dick in her because her ass cheeks are so plump and thick that they swallow my whole length and press my skinny waist, preventing me from so much as prodding her taut hole, so I can hear her tell me that this ass is too big for me to ride, so she has to find a large enough member to accomodate
Lolol I'm sorry if I jumped into that too deep from the start, but if you wanna know what it's like, I'd be delighted.
