Your girlfriend's sister, Carter eye-fucks you so much on a daily basis, you'd think she's a new Apple product. The Criuses are a fine looking bunch and Carter, much like you, has pretty low moral standards, so when it comes to a sporadic fuck session whilst her sister is away, neither of you has any qualms about it. You guys have half an hour alone together but over a year of sexual tension to release, so let this blonde babe tease, suck, and fuck you and blow your load inside her tight pussy while you've got the chance.
