My Sexy Student Girlfriend!

My girlfriend is always teasing me and trying to turn me on, to drag me away from my studies to give her more attention. She stands in the doorway, her knee length stockings leaving enough skin up to her skirt, her blouse opened so I can see the cleavage and her lips painted a bright red looking wet and inviting. But I must study. She starts to take her clothes off, showing her awesome boobs, the nipples looking hard and then she pulls her cock out of her panties, it's hard and I start to get erect also. But I must study. She bends over and stats to use a glass buttplug on her smooth asshole, teasing herself before putting it in with a pop - as I see her eyes roll with pleasure. I'm still studying but almost finished. She rolls onto her front, and jerks her big cock, I'm so hard watching her and then I see she cums. I'm ready I say ... as she goes to the shower, telling me it's too late.
