Now that I knew that Grace was horny for me, my attitude toward tutoring her changed drastically. Yes...I know what a crass bastard that makes me. I did still want to help her, though, and since I had found a way to actually help her improve, I knew I was doing the right thing academically. The fact that she had swallowed my cum on Monday afternoon was another matter. So was the fact that I was sleeping with her mom at every opportunity.
The icing on the cake, though, was Linsdey telling me that Grace was open to sleeping with me and that she (the mom) was fine with it because I was a careful and thorough partner. We had discussed it after we moved upstairs on Tuesday afternoon. Grace was over at a friends and wouldn't be back until late. Lindsey was lying on my chest, limp as a rag-doll after a satisfying orgasm, and my semi-hard cock was still wedged inside her amazing little body.
"If you do sleep with Grace, I hope she feels like this after!" she had whispered as she nuzzled my neck.
"I'll do my very best," I said in response. "But I'm still going to make her learn that Law and Gov."
"You better!" she snorted. "That's what I'm paying you for, right?"
"Right. This whole situation is pretty...unusual, but I actually do want her to pass and graduate."
"Good. That's the plan. I'm just glad you're motivated."
"Lindsey...can I ask you a question?"
"Sure."
"You do know you don't have to sleep with me to "motivate" me, don't you?"
She pushed herself up on one elbow and looked down at me with a serious expression.
"I do know that, and I really do appreciate your professionalism. I didn't count on that when I...made you my first...offer."
I nodded and smiled my appreciation.
"And..." she went on, "I actually didn't realize how horny I was until we got started! That's been the other big bonus to this whole situation. Things have been pretty...slow in that department. Grace's dad is away a lot, and when he's here, he works a lot. It's been a very long time since we were together the way we used to be."
Although we hadn't talked about it, I knew she was still married and I felt a great deal of empathy for her situation. However, I didn't have any experience being "the other man" and I had to think for a minute about what to say. To cover my hesitation, I kissed her a couple of times. Then I laid my head back down, pulled her head onto my shoulder, and whispered my response into her soft, brown hair.
"I'm sorry things are like that. He's missing out on an amazing woman, and I'm happy to be here with you for whatever reason!"
She drew a deep breath and let it out with a shudder. For a moment, I thought she was going to cry, but she collected herself and turned her head toward me, resting her chin on my sternum.
"Thank you," she said simply. "Now can I ask YOU a question?"
"Seems fair."
"Have you ever slept with a student before?"
"Never."
"Ever thought about it?"
