A christmas card by a classmate's mom

You were looking at the most recent post; which was a Christmas card featuring the family of the guy sitting behind you. His mother, Linda, was standing near the center of the shot with her hips bent to slightly show off her ass and her tits, bulging through her tight red sweater, lifted up by a present she was holding under them.

The caption was "making my family happy is the greatest gift" with a few hashtags like #its-the-little-things, #best-mom and #anything-for-family; drawing even more attention to herself than her family in the post, with her superficial grin just overstating how shallow it felt.

Aside from everything else, she still somewhat had that sexy librarian vibe with her thick rimmed glasses and short brunette hair, which she passed to her geek of son, but she also had a cute face with some of it not touched by the various filters she used to enhance herself in the shot.

When the update took affect, you were shocked to see her standing in front of your desk, but obviously influenced by both the filters from the shot and the update adapting to your habits with porn, she seemed a couple years younger(yet still within milf range) , lighter by about twenty pounds and a cup size bustier.

"Mom?" you heard asked from behind you, but you quickly coughed and muttered out "private mode" after some quick thinking.

You turned around and quickly ridiculed "Did you just call the teacher mom?, ha loser", so he turned away out of embarrassment when he saw no one there.

You didn't know much about this guy, but you still had a grudge over one simple reason; which was that he asked to have your seats switched, so you couldn't cheat off him and while you didn't need to cheat, it was still nice using him to double check your usually correct work, but he still had to ruin that.

Looking at the superficial smirk still on his mother's face, You wondered if this copy would be just as superficial as the post would imply.

"Would really you do anything to make your family happy?"

"of course!" Linda cheerfully answered.

"Well your son would definitely be happy if he had me as a friend and I could be motivated if you did something like suck my dick"

"Anything for family" she chimed as she got on her knees and pulled your cock out.

She went straight to sucking, with one hand jerking at your base and the other fondling your balls, but you wanted to make things more interesting, so you tore open her sweater to reveal her bra bound tits, which you quickly freed, while pressing the back of her head further down.

It wouldn't be **** if this was perfectly hidden from the geek, so once you had her audibly throating you, you made a fake cough to hide the commands "public mode, private mode" which you said on repeat to subliminally get his attention, until he looked over and you quickly chose to remain in private mode with his shocked expression showing his disgust at having seemingly imagined her like that.

She slowly pulled off and rested her hand on the small tent under his desk, lightly stroking, with her head following, her gaze focused as she muttered "it's the little things". You quickly smacked her with your hand before following up with slapping your dick to her cheek as well while you corrected "No, it's actually the big things"; upset at her for turning away and trying to cuck you with the geek you were cucking.

"back to motivating me"

"anything for-*gluck**gluck**gluck*" this time she was interrupted by you willfully fucking her throat, hoping to bruise it, as punishment.

You quickly got bored of her kneeling position, so you pulled her up to lay with her back on the desk and her head hanging over as you resumed fucking her throat. You couldn't resist giving the nerd the same subliminal treatment as earlier and you even made him watch flashes of her sucking your balls while you fucked her large tits.

While he seemed obviously disturbed mentally, you decided to take things a step further when you ordered Linda to bend over your desk; facing him as you stood behind her taking her pants and panties down. Entering her tight ass, you smacked it and joked "best mom more like best slut" as you rammed in deeply with her biting the top of your seat to quiet her groans.

Plucking her head up, "come on he likes this, you saw that small little tent earlier, so try saying it, be the best slut"

"Ohhh I Um I'm the~the best Ohhm the best *smack*!"

"Tell it to him" you said while loudly clapping her cheeks and smacking her ass with your spare hand; drawing more attention during your subliminals.

"Ahhh I-I-I-I *smack* MOMMY's the best slut!!!" Linda shrieked as her whole body spasmed around you and in that moment you admired the view bounced between two pairs of glasses with her superficial smile contorted in pleasure.

After thinking for a moment with her slumped over the desk, you realized that there was only one sight that could top the psychological damage of the last one, as you flipped her over and spun her around with her cunt facing the geek in middle of a panic attack.

You sheathed into her cunt determined to stretch it out for some gaping imagery, with it still twitching in the aftershocks of her last climax, and since you were mostly finished just using her ass, you quickly fired a load trailing down her cunt and further shot over her tits and face; using her thighs around you during the money shot given that a phone can't give a thigh job, thus private mode hides the whole process to remain private.

Seeing his mother impregnated left the geek in a catatonic state, what was your grudge again? 'Who cares?' you thought as you sat back down and pulled Linda around to nurse your prick back to hardness.

Looking over to your classmate on the right, you saw that they were on facebook and that the post that you had thoroughly fucked was changed drastically.

The caption read "Making a family and my cuck son happy is the greatest gift" with hashtags like #its-the-BIG-things, #best-SLUT and #anything-for-DICK; drawing attention to herself as a massive slut in the post, with the picture replaced with a slide show of pictures and gifs of her being pounded with there even being a video included ; luckily you're consistently cropped out of shot with her son shown holding his phone at his desk like he was filming.

Your classmate quickly tagged her mom, Sheilah, and asked "Isn't this your friend?" who immediately posted, enraged that her friend would just post about an affair, "I want to know why you think this is acceptable".

Suddenly your dick felt very distinctly unsucked, as you looked forward and saw Sheilah, a blonde milf, standing in front of you in the same yoga outfit from her last post; with Linda likely banned you figured that her post is now the most recent just as you remembered that the girl to your right still hasn't returned your spare pencil yet; truly a unforgivable grudge.

"would you give anything for me to teach you why she thought it was acceptable?"
