botty means

That was when Daddy moved into place behind me, just as I was really getting into it. He grabbed and lifted me by my hips, and I obediently pulled up my knees, holding myself up as he pushed himself into me again. I gasped loudly, and I guess the sudden exhale of breath over Mom's clit must have really felt good, because so did she. Either that, or she was finally coming to grips with the idea of Daddy fucking me, and she just liked getting to see it again. Maybe both, actually; I hoped it was both. Daddy started thrusting, and I wrapped my arms around Mom's thighs, holding tight and securing myself in place so the movement wouldn't make me accidentally hurt her with my teeth. It was so, so much harder than they made it look in porn, trying to concentrate on eating Mom's pussy while I was also getting fucked! But I found I was gradually getting better at it, and by the time Daddy was finally cumming in me again I think I'd managed to give her one for every two that he'd given me. Not as many as I'd hoped, but I think that was pretty good for my first time, and only having my mouth to work with instead of Daddy's miracle cock!

Her dad nodded, but he didn’t look convinced. He gently pinched her big toe and asked, “How about a deal? I give you massage if you go to bed right after, how does that sound?”

“Unnnnh!” I moaned happily. It went in much easier than it had the first time, after several days of near-constant practice, but it was still really a stretch for my poor, tiny, tight little teenage pussy! I tried to maintain eye contact with Mom as it was happening, but I just couldn't help them fluttering closed. I pushed myself back a bit, getting myself to the height I knew Daddy liked best and making my cute little ass really pop for him, then leaned down to rest my head between Mom's big, soft D-cup titties.“Babe?” Mom asked tremulously, her voice weak and thready.
