Bend her over it

Once you reach the bench, you turn her around so that her back is to you. Placing one hand on her hip and the other on her shoulder, you bend her forward, hinging her at the waist. Mrs. Allen puts one foot up into the bench while steadying herself with a hand on the wall, giving you a better view of her plump ass while spreading her legs apart for you. Sliding your hands over the small of her back, you move them over the tops of her hips, then fondle the thick globes of her ass. Squeezing them pulls apart her cheeks, giving you a glimpse of her brown, puckered asshole.

As you admire the view in front of you, Mrs. Allen reaches between her legs with her free hand and grabs your shaft, guiding the head of your cock to her opening, then moves herself back against you. Her stretched pussy is still slick with your cum and gives minimal resistance, allowing you slide your full length into her easily. Mrs. Allen begins working your length in and out of herself, her ass jiggling as she smashes into your hips with each thrust back against you. Glancing over her shoulder at you, she sees you staring at her ass and smiles at you. "You like that ass, don't you? You dirty, little boy. I gave you the chance to go home and pretend like this never happened, but instead, you followed your girlfriend's mom into the shower to fuck her doggy style!"

Grabbing hold of her hips, you match her pace, slapping your balls against her clit with each thrust. "I love this ass!" you say, bringing a hand down hard against her jiggling cheek and instantly bringing a red flush to the skin. "And I love how your pussy feels wrapped around my dick! I could fuck you all night long and not get tired of it! You love it too you dirty, little MILF! You're the one who blackmailed me so that I'd fuck you instead of Tia tonight! What kind of mother does that to their daughter!? You deserve to be punished!" you say, slapping her ass once again.

"Ooowwwww! I know, I'm naughty! Spank me again! Slap my ass! Punish me!"

"SMACK!" "SMACK!" "SMACK!" Again and again you bring your hand down on Mrs. Allen's reddening ass cheek. Squeals of pain mixed with pleasure escape her mouth with each one. You feel her hand reach between her legs and begin to diddle her clit, your balls bumping against her fingers with each thrust. Mrs. Allen really seems to be enjoying having her ass spanked and, thinking about the anal beads you found in her drawer earlier today, you figure she'd enjoy having her ass played with as much as her daughter does, if not more. Taking the decision upon yourself, you place your thumb against her puckered hole and slide in to the first knuckle, then push the rest of the way in and quicken your thrusts.

"OH! David! OH! OH! Oh God! Please! hmph… hmph… hmph… don't... stop..."

"I knew you'd like this! I did this same thing to Tia just this morning and she went crazy! Now I see where she gets it from!"

"Ooooh, I love having my ass filled while a thick dick is buried in my pussy! Oh God! Yes! Yes! Yes! Don't you dare stop! Oh, Oh, Oh, Oh, Oooooooooh! FUUUUUUCCCCCKKKKK! FUCK! FUCK! FUCK!" Mrs. Allen's body spasms uncontrollably and her hand slides down the wall, dropping to the bench to steady herself as you keep up your unrelenting pounding.

As her spasms begin to subside, you pull your thumb from her ass and slow your pace to regain your breath. You know if you kept that pace up, you'd be cumming soon, and you're not quite ready to do that yet. Looking down, you take in the view of her gaping asshole and begin to fantasize about burying your dick in there next; you also really want to find out how good Mrs. Allen's oral skills are; or you could just enjoy the moment and cum in her pussy again.
