My girlfriend chokes my penis with her tits

This girl never imagined she would grow up to have the biggest boobs in town. As she got older her tits got bigger and bigger and it got to a point where she had to buy extra large shirts and bras to keep them. All the guys approached her with the intention of fucking her and the girl is tired of feeling used. Now she got a boyfriend who is the opposite of the previous guys, they have been dating for three months and he has not pressured her to have sex. The girl decided to fuck him and the first thing she asks him to do is to lubricate her tits so she can masturbate his penis with them, and the tits are so big that the boy's penis gets lost in them.
