Extra credit

Marcy just doesn't understand Algebra! Her step-father offered her teacher extra cash to tutor her at their house after class a few days a week. But she STILL doesn't understand. AND... Mr. Johnson spends A LOT more time staring up her skirt at her pretty pink cotton panties then tutoring her anyways. Frustrated and bored with Algebra, the next time Marcy catches Mr. Johnson looking she calls him on it, teasing him, "I don't think my Step-Daddy is paying you to check out my panties..." Mr. Johnson argues a little but Marcy keeps teasing, sliding her skirt up and showing off her panties to her teacher. She knows he likes it. She knows what he wants. Maybe... if she gives it to him, tutoring will get more interesting.. AND she'll get an A in Algebra! As she takes her panties off and wraps them around her teacher's hard cock she giggles, "You can use my hands... my mouth.. and my tight pussy... but I want you to fill my panties with cum." How can her teacher say no?
