By this time, Liz was supporting her upper body by gripping my shoulders with her strong, small hands. I was fondling her taut asscheeks with one hand, and gently rolling her one nipple between the fingers of the other. She was taking long, slow strokes on my meat, sometimes rocking her hips forward and back, sometimes from side to side.
I wanted to wait to cum for a week or two, just so I could experience more of her pleasure. But after about fifteen minutes, I knew that wouldn’t be possible. Liz could feel the changes in me as I moved toward orgasm.
“Fill me, Doc,” she whispered. “Cum inside me. I need it.”
When I was ready, I pulled her down onto me, stopping her movement, pushing myself as deep into her as I could. As the third stream of my cum spurted inside her, the strong muscles of her vagina began their wave-like movement. This time, the only sounds we made as we came were sighs.
After a few minutes, she pulled herself off my softened cock and kissed me. These kisses were different from the one we had shared when she first got in my van. They were the kisses a tired and well-fucked woman gives to a tired and well-fucked man.
We cuddled for a while, her head on my chest and her one thigh across my belly. “Doc?” she said.
“Yes?”
“I don’t want to fall in love with you. You’re my professor, and I know we shouldn’t have done this, but I do want to be with you again. When we get back to school, can I see you?”
“You know I’m married, don’t you?”
“Of course. I took several courses with your wife. I really liked her. The first time I saw her I thought she was a grad student. I was shocked when I found out she’s, like, in her mid thirties. She’s gorgeous,” Liz said.
“You think so?” I asked.
“God, yes. She’s sexy as hell, even though she tries to look professional. You could tell a lot of the guys in class would like to fuck her. Hell, I’d fuck her.”
“Really? You like women?” I asked.
“Well, I dunno,… I’ve thought about it,… I think everyone has at some point.”
“Would you like to come to our place for dinner? Maybe some entertainment afterward?” I asked.
“Oh, well, I don’t know, I’ve never,…” she stammered. “Sure.”
“I’ll see if I can arrange something,” I said.

The rest of our stay at the dig was spent working hard, repairing the slight damage the storms had caused and making up for the time we had lost. Liz and I worked side by side, but we both tried to act like our night together hadn’t happened. There was only the occasional smile or long look, and I think we did a pretty good job of looking innocent in front of the others.

On my first night back home with Cindy, we didn’t get much sleep. She dragged me into the shower almost the moment we got back home. When we started running out of hot water, we dried our tired bodies, sated for the moment, and made dinner. As we ate, I told her about my time on the dig. I wasn’t sure how to tell the story about Liz, but Cindy knew something was up.
“Paul, you’ve told me about your findings, the artifacts, and your male students. But you haven’t said anything about the girls,” Cindy said.
