Dolly was assigned to be your study buddy! You go to her house (without telling your girlfriend) and she excitedly welcomes you in! You sit down together and both begin to get your notes out, when Dolly realizes she's forgotten hers at school! She asks if you can share and tells you to come sit next to her, but you accidentally find yourself looking down her shirt. She catches you and tells you not to be embarrassed, she's just worried that your girlfriend is depriving you from the attention you deserve! it IS an anatomy anatomy course, so maybe some physical studying can help you pass the test! Dolly pulls her panties off and tells you to get your dick out so the real studying can start. She sucks and slobbers on your cock until it's wet enough to slide in her asshole. Her ass tightly wraps around your dick as you pump in and out of her, she smiles, whines and tells you how much she loves it. Just cause it's a science class doesn't mean we can't throw in some math, she counts down from 10 with a vibrator on her clit until you two cum together. Maybe if you break up with your girlfriend, you can come back for more studying tomorrow!
