Sarah is your friend with big tits that you've always had a crush on. You wish you could get someone with boobs as big as hers, but unfortunately the girl you're dating only has C cups. While hanging out one day, Sarah straight up asks if you jack off to her, claiming she notices you checking out her tits all the time. You deny it, not wanting to seem like perv, but she just won't let it go. She lifts up her shirt and shows you the tight fitting bra she's wearing. She talks about your girlfriend's small tits and how you probably wished your girlfriend was as big as her. She notices you getting hard and wants you to jerk off while she takes her big tits out and shows them to you. She takes off her bra, shaking and sucking on her huge natural tits while insulting your girlfriend's C cups and begging for your cum.
