You're supposed to your new study partner today, but she forgot and you walk in on her masturbating! She covers up with a pillow, but you notice her trying to hide that she's still grinding on the pillow now! She humps her pillow and eventually starts to finger herself, excited that you're watching her. She gives you a blowjob and asks for you to cum in her mouth so you'll last longer when you fuck! You cum in her mouth, and she rides your cock until she's begging for you to fill her with cum!
