Jealous Backdoor Encounter with Busty Partner During Ruins Exploration

I am Takumi, an antique collector in my mid-thirties. I love old things and enjoy hunting for dusty furniture or rusted lamps. On weekends I always wander alone through abandoned buildings on the outskirts of town. Lately I teamed up with Nova, whom I met online. She works as an exploration tour guide, a woman in her late twenties. Even before we contacted each other, I saw her profile photo and felt my chest stir. In that picture her tight shirt emphasized what looked like G-cup breasts, making my heart pound like a drum.

We met at dusk in autumn at the ruins of an old factory on the edge of the city. The leaves had turned red, and a cool wind brushed my cheeks. The entrance was broken iron fencing with fallen leaves piled at our feet. The air felt damp, and only the faint sound of distant cars reached us. I stood there with my backpack on and flashlight in hand.

Nova appeared wearing black leggings and a loose sweater, her hair tied in a ponytail. As she walked, I could see her large breasts swaying heavily beneath the sweater, like two ripe fruits defying gravity. Their volume was obvious even through the fabric, creating a deep shadowed cleavage. I looked away at once, but inside I thought, “If I touched breasts that big, what would they feel like… soft, warm, maybe my hands would sink right in.”

“Takumi, hello! Nice to meet you, I’m Nova. Thanks for coming today. These ruins are really interesting—lots of old machinery left behind.”

Her voice was bright and her smile cute. We entered the ruins. The concrete walls were cracked, glass shards scattered across the floor. Orange sunset light streamed through the windows, stirring up dust. Our footsteps echoed, giving the place an eerie feel. Nova led the way with practiced ease while I followed, searching for antiques.

“This used to be a factory fifty years ago. There might be old tools lying around. Look at this shelf.”

On the shelf she pointed to were rusted metal parts. I crouched to pick one up and brush off the dust. She crouched beside me, her large breasts pressing close against her knees. I caught the sweet scent of her shampoo, tickling my nose.

Conversation flowed easily. Nova told stories about her explorations and I proudly shared my knowledge of antiques. She listened with an impressed expression. Then, suddenly, old jealousy resurfaced. A few weeks earlier I had seen Nova chatting cheerfully online with another male exploration partner. That man had commented “Cute” on her photo, and she had replied “Thanks!” I had felt my chest tighten through the screen and couldn’t sleep all night thinking about it. “They’re probably obsessed with her huge breasts. I haven’t even had real contact yet… jealousy is driving me crazy.”

Twilight deepened and the ruins grew dim. We had reached a back room and were examining an old desk when Nova suddenly pulled out her phone and showed me a photo of another man.

“This guy joined one of my previous tours. We made an interesting discovery. Look, this old clock!”

In the photo the man stood beside Nova, smiling, his hand almost touching her shoulder. Jealousy flared inside me.

“You sure get along well with other men, Nova. I’m just some collecting nerd.”

My voice had dropped. Nova turned, surprised.

“Huh? What’s wrong, Takumi? You seem upset all of a sudden.”

Her large breasts rose and fell with her breathing. Unable to hold back, I continued.

“It’s those chats. Those guys are happy just looking at your… chest, right? I haven’t had that experience, and it makes me jealous.”

The air in the ruins grew heavy. Wind rattled the windows and leaves rustled outside. Nova’s eyes grew slightly moist as she looked at me, the last sunlight tinting her face red.

“You were thinking that, Takumi? I’m just having fun with everyone. But… it’s kind of nice that you’re jealous.”

She stepped closer. My heart raced. The flame of jealousy began turning into something hotter. Nova’s hand touched my arm, her warmth reaching me through the cold air.

Then everything changed quickly. Nova’s eyes gleamed mischievously and she pulled me in, whispering in my ear.

“Then prove it. Show me you want me the most.”

I couldn’t stop. Fueled by jealousy, reason vanished. I pressed her against the wall and pushed her sweater up. Beneath it were G-cup breasts wrapped in a black bra, the lace stretched tight, the heavy flesh threatening to spill out. Breathing hard, I unhooked the bra. Pale breasts tumbled free, large pink areolas and already stiff nipples. They felt soft yet springy in my hands, too big to fit in my palms, like warm jelly.

“Ah, breasts this big… first time in my life. Maybe being jealous was worth it.”

Nova giggled.

“Takumi, you’re really into them. You can touch more.”

I began kneading the huge breasts with both hands. My fingers sank in, flesh overflowing. When I pinched her nipples she trembled. Her breath grew hot. My cock hardened painfully. I stripped off my pants and exposed it. Nova’s eyes lit up.

“Wow, Takumi, it’s so thick and hard…”

Her hand wrapped around my cock, warm and gentle as she stroked. Unable to wait, I pulled down her leggings. Beneath her panties I saw a bush of hair and her wet pussy, lips swollen, clit peeking out. I touched it with my fingers, slick arousal coating them.

“Nova, you’re so wet… hot.”

She swayed her hips.

“It’s your fault. Put it in already.”

Still riding the wave of jealousy, I made her get on all fours on the dusty floor. Her round ass lifted, pussy spread open. I gripped my cock and pressed against her entrance. The fire of jealousy drove me. I would dominate Nova more than any of those other men.

I pushed in slowly. Her walls clenched hot and slick around me. Nova moaned.

“Ah… Takumi, you’re big…”

I drove in to the hilt. From behind, her huge breasts hung and swung heavily with each thrust, slapping audibly. I reached forward and grabbed them from behind, flesh spilling between my fingers. Every squeeze made her pussy tighten.

“This sway… who knew jealousy could feel this good. These huge breasts are mine alone.”

I thrust faster. Her moans echoed off the walls. Fading sunset light stretched our shadows long. Sweat, her scent, and dust filled the air. Each time my cock struck deep she shook. When I rubbed her clit she cried out.

“There… my clit feels so good! Fuck me harder, Takumi!”

Fueled by jealousy I pounded into her from behind. My tip hammered against her cervix. Her breasts deformed in my hands, nipples pulled taut. Arousal dripped down her thighs. The sound of my balls slapping her ass filled the ruins.

“Nova, are you going to come on my cock? Better than those other guys, right?”

“Yeah… Takumi’s the best! Your jealous face turns me on… ah, I’m coming!”

Her body convulsed, pussy clamping hard around me. Pulled over the edge, I came too, pulsing thick loads deep inside her. I leaned against her ass, still squeezing her breasts as I emptied myself in seven or eight heavy spurts.

Afterward we collapsed onto the floor. Her large breasts pressed warmly against my chest. We breathed hard, bodies slick with sweat. Night wind blew in from outside, cooling our heated skin.

“Takumi, that was amazing… jealousy led to this. You’re bolder than I expected.”

Nova laughed. Embarrassed, I touched her nipple again, the soft sensation filling me. “With this, my virgin-like fantasies became real. But it still isn’t enough… I want to drown in these breasts forever.”

Later we left the ruins and returned to the city. The fire of jealousy had faded, replaced by a sweet afterglow. We promised to explore together again, this time in deeper places. My collecting habit seemed to have shifted to her huge breasts.

“Still, the memory of those swaying breasts torments me every night. The tight grip of Nova’s pussy, the pleasure around my cock… I can’t go back.”

The twilight ruins quietly held our secret. Only the rustle of leaves could be heard in the distance.
