Grinding My Hot Mom's Ass on the Riverside Bench – Pure Love with Discipline? Chapter 67
"Why? Did it hurt?"
"That's what you call it?"
I grabbed Mom's wrist with my left hand just like last time and smacked her ass again with a sharp 'smack!'
"Ow!"
Mom started stroking her ass with her right hand again.
Every time I spanked her, the plump flesh of her ass would 'jiggle♡~' so enticingly.
And watching her hand caress the spot I'd just hit was incredibly sexy and stimulating.
She'd been standing there rigidly, kneading her ass, but now she started stepping toward the bench as if trying to escape me.
I let go of her hand and followed, whipping my palm down on her ass with a 'slap!' like a lash.

"It hurts~ Stop now~"
Mom stopped in front of the bench.
I recalled how she'd fidgeted restlessly last time when that creep groped her.
'That insolent bitch!'
After that guy molested her, her arousal level—uterus capacity—had shot past 80%.
I slapped her ass with my palm again.
The 'slap!' echoed into the darkness.
Maybe because it stung, Mom didn't even think of sitting on the bench; she just knelt there obediently, standing still.
I spanked her ass once more while pressing down on her lower back, forcing her to grip the bench and bend over.
At first she'd whined about how it hurt, but now she stayed silent, just as I wanted—hands braced on the bench backrest, thrusting her ass out 'nice and far~' in an almost prone position.
Her already plump ass strained against her skirt like it might rip it open.
I couldn't hold back and swung my palm at that impossibly sexy ass one more time!
- Slap!
Every time my hand struck, Mom shook her ass left and right, as if trying to shake off the pain, her movements so lewd.
My cock was rock-hard in seconds, tenting my pants forward like a missile.
The urge to rub against her ass surged up!
'Fuck, this horny mom bitch! I gotta make sure she never shakes this ass in front of other guys!'
'Not even Dad gets to touch Mom's ass anymore!'
'This perfect, jiggly ass is mine and mine alone!'
I could touch it, spank it—only me! Her ass was too damn tempting!
Unknowingly, my spanking hand came down harder.
"Haat! I said it hurts~"
Mom let out a whimpery cry.
Yet she still perked up her ass like a bitch in heat.
"Got it! I'll go easy, so quit whining!"
'Ah~ I wanna rip her panties off!'
I pressed right up behind her ass, grinding the bulging tent in my pants against her cheeks with a firm 'press press~'.
The thick flesh of her ass clung to my crotch, melting it away so sweetly!
"Ahhng♡~!"
Mom must've felt it too—she started twisting her hips side to side, shaking her ass as if to say no, as if it was wrong.
That only made the friction from her ass flesh press even more vividly against my cock.
'Whoa~'
Hot breath poured out of me like steam from boiling over.
I angled my cock upward so the underside rubbed her ass, then started grinding up and down with a slow 'rub rub~'.
"Hey~ Why are you doing this♡~"
Mom groaned in complaint, but kept moving her ass, making the flesh '♥jiggle♥~'.

'Ah~ I'm going crazy~ Mom's ass!'
I pulled back a bit and smacked her ass and side with my right hand—'slap! slap!'.
The force pushed her ass to the left.
Then I hit the left cheek with my left palm—'slap! slap!'.
Her firm, sleek ass was so alluring it felt like it would make my cock explode from the heat.
"Mom's ass is too sexy!"
I stopped spanking, grabbed her waist with both hands, pressed my tented pants tight against her ass, and started thrusting—pushing forward like I was shoving my cock in, pulling back, over and over.
My crotch swelled to the max, sticky precum leaking out.
'I can't hold it!'
Mom seemed to sense my state; every time I thrust forward to grind, she'd brace her ass harder, pushing back to resist.
'Whoa~ I've held back so much!'
My cock grinding on Mom's ass!
Not skin-to-skin, but the skin that must be red and swollen from my spanks!
Rubbing my crotch against it, shaking side to side, thrusting back and forth, lost in that mushy sensation!
This ass belonged to Mom♥!
And the cock grinding behind it belonged to her son—me!
Our taboo relationship, where she was starting to accept it!
I had to hold back!
But cumming like this would be such a waste—
My passion! Love! Desire for Mom!
I wanted to plunge into her pussy and pound away, flooding her with my hot cum!
My hands slid from her waist forward, caressing her back and sides,
slipping under her armpits,
gripping her sagging tits from bending over, hugging her ass with my thighs and lower belly, grinding my crotch relentlessly 'rub rub~'.
"Ahw~ What do I do♡♥~"
Mom started sighing stickily, 'huff huff~'.
I hadn't noticed at first amid the grass and tree smells, but pressed this close behind her, her musky ♥pussy scent♥ wafted out 'puff puff♡♥~'!
"Mom~ I wanna fuck!"
The words I'd held back burst out.
"Wha... what? You... you're getting way too..."
Mom sensed the danger and whispered soothingly, like coaxing me.
"We can't do that~ You know we can't~ B-but... r-right now..., j-just..., do it..., don't hold back..."
YW9peUx5cktZYXhyU2hzY1VsMkQ0VXBtWjhMUUdRV2trNTR1YTFBOTdRSHE1cGVmSTBEMTcwMERSY0dPWmZlTQ
"J-just... do it now?"
"Y-yeah~"
Mom was embarrassed too, couldn't say it outright, but she was telling me to go ahead—
Release my urges in this position at least...
Not even rubbing her pussy—just cum by grinding her ass?
That'd feel so unfair...
Ahw~ But holding back was too hard...
"Hurry up~"
Mom whispered coaxingly again,
even gently shaking her ass...
The roles felt reversed a bit.
I'd dragged her here,
but now she was urging me on.
Of course, probably worried I'd do something reckless...
"I wanna do it with you, Mom!"
"So do it now, quick! If you can't hold it..."
'I wanna grind my hard cock on your pussy!'
I screamed it in my mind.
Couldn't say it out loud...
"I wanna touch Mom's tits!"
Then Mom hurriedly undid the lower buttons of her half-open blouse,
sliding the front hook up and down to pop it open.
Like she'd worn a front-hook bra just to make it easy to take off!
The cups naturally parted, and her heavy ♥breasts♥ spilled downward.
'Whoa~ So good!'
Her warm, bountiful E-cup tits!
I should've asked to touch them sooner!
Cupping both with my hands sent electric jolts through my body, straight to the back of my skull, my heart pounding 'thump! boom!'.
My crotch trembled 'buzz buzz~' like hit by shocks, even before touching her tits.
It felt twice as hard now...
Grinding that raging crotch on her ass, fingers finding both nipples and pinching as I rubbed my cock wildly against her like mating lions.
"Ahht! It hurts♡!"
Mom cried out sharply.
I must've pinched her nipples between my fingers too hard!
Lost in the moment, no control.
Her voice urging me to do it now still echoed vividly in my head.
'Ah~ Can't hold it anymore! I'm gonna cum! Right here if I have to!'
Caught in that thought, I started kneading her tits like I wanted to burst them!
"Ahw~ I can't take it~ Gonna cum~"
I murmured it against her ear like a lament, and started the hot release!
"Do it~ Go ahead♡~"
Mom panted from the effort, shaking her ass side to side, wriggling up and down in circles.
Like searching for the thick ridge of my cock between her soaked valley~
Her tits in my palms grew slick with sweat.
Sweat beaded on her ass too, making it damp.
The panties rubbing my cock under my lower belly tangled with sticky fluids, soaking wet and sloshy.
That wet, clammy, slightly gross spot spread up and down, wrapping my cock.
"Ahhuuya~"
A long sigh escaped me naturally.
Pressing my torso tight to her back, her wildly groped tits felt swollen taut.
Her nipples erect like they might pop, trapped in my finger joints.
