Ive never had sex with a large girl, but ive gotten head from several, and they all swallowed. I dont know if there is a correlation. I prefer 'thick' girls. 40 inch ass, and trim-soft mid section. Breasts are not a concern for me. Also, pretty and brunette. My girl is pretty much that, perfect for my taste.
Ive had sex with a real skinny girl, and its not for me. Im not turned on by bone.
