Your girlfriend has a surprise for you. Something that you've been wanting for a long time. She lifts up her dress and turns around. She isn't wearing any underwear, but she is wearing a buttplug. Your surprise is anal! You've been wanting to fuck your girlfriend's ass for quite some time, and now it looks like you will finally be able to! She teases you for awhile. Showing off her plugged ass and pretty pink pussy, saying just how much she wants something bigger in her asshole, how she wants your already hard cock filling it up. As you start to undress, eager to fuck her from behind, your girlfriend stops you. Before you get to fuck her ass, there's something she wants to do first. She wants to fuck your ass! She even bought a strapon just so she could do it! And after all, it's only fair, right? If you get to fuck her ass, then she should be able to do the same to you. You hesitantly agree if it means that you get to finally have anal with her. But, you're going to go first. Your girlfriend has you lay back on the bed and fingers your asshole, getting you nice and prepared for the dildo she's about to have you take. Once you're adequately stretched out, your girlfriends gets between your legs and slides her strapon into your ass. It hurts a little at first, but you soon get used to it. Not only do you get used to it, but you really enjoy it. Your girlfriend even strokes your cock while she is pegging you. The double sensation of pleasure is so intense, so good, that eventually you cum all over yourself. You then ask your girlfriend if you can now fuck her ass... Nope! She wasn't going to let you this whole time! She's been wanting to peg you for awhile now, and she knew the only way you'd let her is if she tricked you! But, all's well that ends well. You can't deny that amazing orgasm you just had.
