My female bestfriend recently moved out to halls for university, and there's always been an underlying kind of sexual tension between us. We're very close - we can talk about anything comfortably, and don't find it necessary to be cringed by sex (which we both are crazy about anyway). We'd often talk about sex, sex positions, sex acts, her boob size, my penis size, and we'd share fanatical stories of sex in different situations - descriptive tellings of how I'd love to get a blowjob while driving, or how she'd love to be fucked raw on the dining table.
