My final German paper was due. And final exams would follow the same schedule as midterms. That meant evening Lab exams and morning lecture exams. The...last one would be biology."Hey," I said to Dawn and Cathy as we settled in for class on Friday. "Angela is coming out to the ranch to study tomorrow. She said she'd help us review if you two want to come out." Really? Our TA? I didn't know you knew her," Cathy said."We're old friends, but I didn't realize she was our TA until after midterms," I. Carefully positions my cock between her wet pussy lips and begins sliding up and down its entire length. Covering it with her warm wetness. She places her lips on mine and whispers soft words past my lips, into my waiting mouth. "And if an evil wizard, with dark spells so powerful, never before seen, guarded the door, how would you break the spell?" She reaches down between her legs, holds my throbbing cock and slowly guides it inside her. She lowers herself on my cock, burying it deep inside. "You're naked!" she exclaimed."Well, so are you," I said. "Almost." So am I," said Lou. "Don't you feel a little over-dressed?" she added.Tricia looked at both of us again and then turned away from us. She reached up and undid the clasp to her bra, shrugged her shoulders and tossed it to the side. She turned back to us her arm holding tightly across her breast, trying desperately to hide them. It was an impossible task, given their size.Lou said, "Um ... What about the panties?" Do I have to?". He is giving the boys a good workout while rubbing his cockhead with his thumb and fingers. "Are you keeping a look-out" he asks. I haven't been but I look around quickly and say "Yes I am".His penis has started to get aroused and he is now jerking his cock more than he is scratching his nuts.It turns out that this is kind of exciting, I don't mind at all. He reclines the seat a little and is now jerking away at a fast steady pace. His cock may have started small but it is now a fully erect 6.
