Smooch her lips, a lot.

You hold her cheeks and smack at her lips, she goes to giggle but it's interrupted by another kiss, and another, and another, each one prompting a burst of quiet, shameful moans from each of you. She places her fingers against your chest and frees from your lips. "S-sweetie, that's enough, you shouldn't kiss your mother like that…" you give a naughty smile and grab her cheeks, pulling her in for more kisses, the two of you staggering until her backside bumps the kitchen counter. "Mmf! M-mmnn…" Your tongue, prodding and pestering finds its way into her mouth, bothering her tongue as it fruitlessly tries to get away. "Gwyn, that's enough, sto-" before she can finish, you're back in her mouth, humming and licking inside her, your cheeks both rosy at this point. With some wandering hands, you pull her waist band down some, revealing her pussy, a bush of pubes coating it. You mumble, "No panties?" As your mother grips the counter, catching her breath as best she can, she sputters down to you. "B-baby, don't do that! That's, nnn, a dirty place, so don't go near it...!" You feel your ears get hot as you wriggle out your skirt, your dick happily prodding at her pussy. "Mmm, Mom, it's so big and hard… It hurts if I don't let it out…" you pout up at her as she pants and breaths, trying to grasp what's going on, before cracking a smile and spreading her legs a bit. "L-let… Let Mama help you then baby girl…" With that, you pounce her excitedly, slicking your dick as far as it's willing to go, your hips pumping and smacking as fast as they can. The two of you pant and moan aloud as your healthy dick slides in and out her snatch, lubing the two of you up with her own natural juices. "G-gwyn! You're so- Nnn! So, b-big!" You smirk to yourself in pride, lifting one of her meaty legs a bit as you thrust more and more, looking at her with soft, lusty eyes. The next few pumps feel like you really pull at your shaft, with a couple long, calculated strokes, your dick spurts and sprays hot cum into her pussy, her own groin spasming and soaking your crotch a good deal as well. You both cry out at the climax, maybe it's in the family, and after a minute of stagnant rest, you pull out, her crotch oozing out cum, dripping onto the floor. This was a good use of your time, you'd say.
