Chapter 1288: Sticky Armpit Cock Reward

"That’s enough smelling..." Haruna announced, her voice still bright with mischief.

Through the briefest flicker of AI Lens, I saw her gesture for Tomiko to bend forward.

Tomiko hesitated only a second before obeying, the open holes of her matching erotic lingerie leaving her stiff nipples, wet pussy, and tight asshole completely exposed as she leaned down.

Haruna took my throbbing, pre-cum-slick cock in her small hand and guided the thick head straight into the soft, warm hollow of Tomiko’s raised armpit.

She pressed Tomiko’s arm firmly closed around the cock, trapping my cock in the hot, slightly damp, hairy crease.

"Hnnngh..."

A low, raw groan left my throat the moment the soft flesh and fine hairs sealed around me. Tomiko began to move her arm in slow, deliberate strokes, rubbing the entire length of my cock up and down inside her armpit.

The fine hairs dragged deliciously along the sensitive skin; the warm, musky scent of her underarm rose stronger with every pass.

The soft, yielding flesh squeezed and released around the thick cock, spreading my own pre-cum and the residual slickness from Kasumi’s earlier grinding all over the hairy valley.

Haruna kept one hand on Tomiko’s shoulder, making sure the pressure stayed tight, while her other hand occasionally reached down to give the exposed head of my cock a cruel little squeeze each time it peeked out from the far side of the armpit.

"So..." Haruna asked, voice low and filthy with amusement, "who do you think this is?"

I dragged in another deep breath of that intimate, salty-sweet scent while Tomiko’s soft, hairy armpit continued to stroke my cock from base to tip. The fine hairs tickled and scraped lightly; the warm flesh molded perfectly around the thick girth.

"This is my Oba-san Tomiko..." I answered, voice rough. "I can smell her hairy armpit... and feel every soft hair rubbing against my cock."

A muffled, embarrassed sound escaped Tomiko against Haruna’s lips. Kasumi’s sharp intake of breath was audible even through the blindfold.

Haruna’s delighted little laugh rang out as she kept Tomiko’s arm locked tightly around my cock for one final stroke, then finally released her.

"Ohhh~ you guessed right," Haruna cooed. "I bet Oba-san’s smelly armpit... he really likes it, so he did remember Oba-san’s nasty smell~."

Tomiko’s face burned. She pulled her arm free—leaving my cock glistening, sticky, and streaked with her soft armpit hairs and thick pre-cum—and gave Haruna’s butt a sharp, playful slap.

"Hmph... you dare tease me like that..."

Haruna yelped and rubbed her ass with an exaggerated pout, making Kasumi and the others chuckle despite their flushed faces and open lingerie.

I was still rock-hard, the thick cock throbbing and shining with the messy mix of pre-cum and the intimate scent of Tomiko’s underarm.

"So... is there any reward?" I asked, voice rough.

Haruna’s eyes sparkled. She stepped behind me, reached up, and untied the blindfold. Soft light flooded back in. The first thing I saw was Tomiko standing right in front of me, breathing unevenly, her entire body on full display in the special erotic lingerie.

The open holes framed her stiff, dark nipples, her glistening wet pussy, and the tight, wrinkled ring of her asshole. Her right armpit was still shiny and sticky from the earlier stroking, fine hairs matted with my pre-cum.

Haruna rested her chin on my shoulder from behind, smiling wickedly at her aunt.

"Oba-san... why don’t you reward Jack? He guessed you right~."

Tomiko’s cheeks were deep red, but she didn’t step back. Instead, she raised her arm again, the open lingerie leaving every other part of her completely exposed, and looked at me with a mix of embarrassment and heat.

Haruna immediately took control of the reward. She wrapped her small fingers around my throbbing, pre-cum-slick cock and guided the thick, swollen head straight back into the soft, warm hollow of Tomiko’s raised armpit.

She pressed Tomiko’s arm firmly closed around the cock, trapping every thick inch in the hot, slightly damp, already-messy hairy crease until the soft flesh completely swallowed the length from base to tip. The sudden heat and tightness—now even slicker from the previous round—made my cock jump hard.

"Hnnngh... fuck...!"

A low, raw, broken groan tore from my throat the moment the soft flesh and fine, pre-cum-matted hairs sealed around me again. The heat was intense—wetter, tighter, and filthier than before. Soft, fine armpit hairs, now sticky and clumped with my earlier leakage, scraped and tickled along the sensitive underside of my cock like tiny, teasing fingers.

The warm, musky, slightly salty scent of Tomiko’s underarm rose stronger than ever, flooding my nose. It smelled like warm skin, faint sweat, perfume, pure feminine heat, and the sharp, intimate scent of my own pre-cum mixed into her.

Haruna kept one hand on Tomiko’s shoulder, forcing the pressure to stay brutally tight, while her other hand occasionally reached down to give the exposed, leaking head of my cock a cruel little squeeze and twist each time it peeked out from the far side of the hairy valley.

"Move your arm, Oba-san," Haruna ordered, voice sweet and filthy at the same time. "This is his reward. Stroke that fat, dripping cock with your armpit. Nice and slow at first... let him feel every single soft, sticky hair dragging along his cock. Make it even nastier for him this time."

Tomiko, face still burning but no longer muffled, began to move her arm in slow, deliberate strokes. The soft, yielding flesh squeezed and released around the thick cock, rubbing the entire length up and down inside the hot, hairy crease with wet, sticky friction.

Fine hairs, already matted and shiny, dragged deliciously and roughly over the sensitive skin; more of my fresh pre-cum welled from the tip and smeared everything into an even slicker, filthier mess.

The wet, slightly sticky, obscene sound of my cock being stroked inside a mature woman’s armpit filled the quiet room—soft schlick... schlick... schlick mixed with the faint rustle of those soft, now thoroughly cum-stained hairs.

From nearby came a cluster of embarrassed, half-whispered reactions.

Kasumi’s voice was shaky and scandalized.

"Haruna... this is too much... using her armpit like that again... It’s so dirty..."

Jayden let out a soft, flustered scoff under her breath.

"She’s really stroking him with it as a reward... look how wet and shiny it’s getting..."

Claire’s murmur was low and disbelieving.

"I can’t believe she’s actually doing that... and he’s leaking even more..."

Yuko’s quiet, embarrassed voice followed.

"Oka-san’s sister... and she’s rewarding him with her armpit... It’s so shameless..."
