You haven't been able to get ahold of your girlfriend all night while she's been out with her roommate at the bar, so when you hear her roomie come in alone you decide to question her about your girlfriend's whereabouts. It turns out your girl was never out with her friend to begin with! The roommate delights in telling you about a new guy who's been texting your girl - and how much bigger his dick is than yours. It turns out your girlfriend has been talking bad about your size for a while and she finally decided to get the big dick she needs.  Her bitchy roommate seems to enjoy your humiliation. In fact, she says your girlfriend doesn't know how to properly treat a guy with a small dick, but she does. She gets you to admit that you get off on small penis humiliation and even has you eat her out while you jerk off thinking of your girlfriend getting railed by a bigger cock!
