The Heart System

Slowly, I began to move, pulling back almost to the tip before sliding deep inside her again. The friction was incredible, every stroke accompanied by the wet, rhythmic sound of our skin connecting. As the tightness began to give way to wet friction, I raised one hand and delivered a firm, stinging smack across her left ass cheek.

The sharp crack echoed in the room, leaving a bright red handprint on her skin. Minne let out a lewd, trembling cry, her hips automatically jerking backward into my next thrust.

“Does that feel good, you little pervert?” I whispered, my voice thick with lust as I picked up the pace. I leaned forward, my chest pressing against her bare back as my hands moved up to knead her breasts from underneath, pulling her back against me with every heavy slam. “Look at how easily you take my cock. You were made for this.”

“Yes, Master… ah! It feels… amazing… fuck me harder!” she cried out, completely discarding her usual shyness as the pleasure took over.

I obliged, locking my hands onto her hips and driving into her with a relentless, punishing rhythm. Her ass cheeks bounced against my thighs with every deep thrust, the friction inside her tight passage pushing me closer and closer to the edge.

In the middle of the heavy friction, Minne suddenly turned her head back to look at me, her eyes completely glazed over with lust. “M-Master… p-please… l-lick my…”

“What?” I panted, throwing my hips forward into another deep thrust. “Lick what, Minne?”

“My… arm…pits… Master,” she whimpered, her face turning bright red as she confessed it.

I let out a low chuckle, a smirk tugging at my lips. I leaned all the way forward, pinning her chest flat against the mattress. I reached one hand under her, lifting her arm up to expose her smooth, pale armpit. I buried my face there, dragging my warm, wet tongue right across her sensitive skin, licking her deeply while my lower half kept ruthlessly burying itself inside her ass.

It was completely bare, damp with a fine sheen of sweet, clean sweat from the heat of the room and the exertion of her earlier orgasms. I buried my face straight into her, pressing my open mouth against the soft flesh. I took a long, slow, wet stroke with my tongue from the base of her upper arm down into the very center of the sensitive hollow, swirling it deeply against her skin.

Minne let out a high-pitched, breathless shriek, her toes curling into the mattress as her internal walls clamped down around my shaft with an unbelievable, vice-like squeeze. The unique texture of her smooth skin against my tongue, mixed with the slight, intoxicating scent of her fresh sweat, sent a massive jolt of arousal straight down to my groin. I couldn’t get enough of it; I kept my mouth glued there, delivering a flurry of fast, wet lapping motions that covered the entire hollow in a thick sheen of my saliva.

Minne squealed loudly, her entire body shaking from the intense, overwhelming combination.

“You really are a pervert, huh?” I teased, my voice thick with lust as I nipped playfully at the soft flesh of her armpit before licking it again. “First you love sucking my fingers, then you love getting your armpits fucked, and now you want me licking them while I take your ass? You’re completely obsessed.”

“Y-yes… ah! I’m your… little pervert, Master!” she wailed, her hips lifting and slamming back against me, completely broken by the dual stimulation.

Uh-oh. Bad boy points. I had to calm down.

The sheer visual of her on all fours, completely bare and yielding to my tongue and my cock while Mendy was just down the hall, made my blood boil with heat.

“I’m going to fill you up, Minne,” I said, my breath ragged as I slammed into her deeper, bottoming out completely. “Hold still for me.”

“Give it to me, Master!”

With a final, powerful thrust, I buried myself into her as deep as I could go. My vision went hazy as a massive wave of release ripped through me. I held her hips in a vice-like grip, throbbing violently inside her as I pumped thick, hot streams of semen directly into her tight, twitching depths. Minne wailed, her own internal walls spasming around my shaft in a desperate, clinging grip as she rode the high of her own release.

We stayed like that for a long moment, panting heavily in unison. Finally, I slowly pulled out with a soft, wet sound. I collapsed backward onto the mattress, lying flat on my back, completely naked and drenched in sweat.

Minne trembled for a second on her hands and knees before slowly turning around. Her legs were shaky, but she crawled across the sheets toward me on all fours, her eyes locked onto my throbbing, half-hard dick. Without needing a single command, she leaned down, her lips parting as she took the head into her warm, wet mouth and began to suck on it gently, her tongue swirling around the tip to clean me off.

I smiled down at her, letting the tense energy in the room settle into something softer. “You did so good for me, Minne,” I murmured, running a hand down her bare back. I slid my fingers down between her cheeks, finding her tight, slick entrance, and began fingering her ass slowly, easing inside with a gentle, rhythmic slide.

Minne let out a long, trembling moan, her body arching into the touch, but she didn’t stop what she was doing. She kept her mouth glued to my length, her warm tongue licking up and down the shaft as I worked my fingers inside her.

Then, the bathroom door clicked and swung open. Mendy stepped back into the bedroom, completely refreshed and dressed in her fresh clothes.

“Hey,” I smiled, not breaking rhythm as I kept fingering Minne’s asshole. “You’re out quite early.”

She shyly nodded, her cheeks turning a light pink as she looked at us. “I have to go and pick up some stuff for the night… oh, god. I forgot to let you know.”

“What?”

“We were so into it that…” She shook her head with a small laugh. “Penelope called us for dinner. It’s her birthday.”

“Oh… really?”

“Yep. Will you be coming? It’s at nine.”

“Sure,” I said, leaning back comfortably. “I’ll grab some, uh, dunno, sweets for her, or cakes, maybe? Donuts? What does she like?”

“M-may I bite it a bit, Master?” Minne asked in a muffled whisper, pulling back just enough to nibble playfully at the sensitive head of my cock.

“Of course, honey. Don’t hurt it.”
