A few weeks had gone by since Lyn and I had had our first fuck. In that time, we had explore, discovered, learned. We knew far better than before what each of us liked, didn't like, etc. - though we were still quite tentative in our explorations, still sometimes fearful of voicing our thoughts, desires. But all in all, our sex life growing day by day. We found new and different ways to get together for sex, sometimes doing homework, sometimes going together to bring the cattle to the barn (and of course finding time and space down by the river, well hidden by the trees, to engage in joyous fucks). Life suspected, and hoped, that Lyn was experiencing the same.
A few days into that first week, the whole family was seated around the kitchen table, having lunch. As usual, Mel sat on my right. We all chatted away about anything, and nothing.
At one point, Mel turned to me and said "Ron, I was wondering if you could help me with my homework." That was a bit strange, but okay with me. Then she dropped her left hand under the table. She turned to Mom, saying "Lyn told me Ron really helped her with her homework, that he was really good at helping her learn, and that she was learning a lot."
I froze. WTF!? What did she know? What would she say?
Her fingers now touched my right leg, ran gently up and down it. I couldn't move, my mind racing. I was scared stiff. I realized i was also becoming stiff in another way. She turned to me and continued.
"Lyn told me she found it really hard, but that you had a way to get into things that she has come to really appreciate."
Her fingers probed a bit between my legs. Involuntarily, I let my legs fall open, slid my butt slightly forward on the seat, but not enough so anyone would notice.
She turned back to Mom. "I thought if Ron could help me the way he helped Lyn, that would be great." And with that, she placed her hand fully on my crotch, gave it a little squeeze.
By now I was rock hard, and she knew it. She continued to fondle and squeeze as she turned to me, saying "I would really appreciate if you would help me the way you helped Lyn. And I promise I'll do everything I can to take in what you're giving me."
Mom looked pleased as could be by what she was hearing, about how Lyn and I, and now Mel and I, were getting on together with our education. I knew what she was thinking was not at all what was happening, and I thanked my lucky stars for that. I thought quickly.
I turned to Mel and said "Well, I need to clear the table after lunch. Why don't you go up to your room, get all your stuff ready. As soon as I'm done here, I'll come up and we can see what we can do together."
Mel smiled sweetly, said "Thanks, that would be great." She give my crotch another quick squeeze, brought her hand from under the table, and went back to eating. Conversation continued to flow.
When lunch was finished, Mel headed upstairs. I took a few minutes to clear the table, then headed up to my room. There, I stepped out of my trousers and underwear, then pulled my trousers back on, but didn't do up the zipper or buckle.
