Morning Jog Breast Grab Leads to Steamy Outdoor Sex with Runner

On an autumn morning, the suburban jogging trail was filled with a pleasant air as the leaves began to turn red and the tree leaves made a crisp sound. I am Daiki, a 24-year-old assistant fitness coach. My main job is training newcomers at the gym, but I always run this path in the morning to train my body. I love sweating, especially the feel of the cool autumn breeze caressing my skin. Today I was moving my feet lightly along my usual route.

The path is not very crowded, but I occasionally pass other runners. I picked up my pace, breathing hard as I cleared a hill, when I spotted a female runner coming toward me. She wore a black sports bra top and leggings, with sweat glistening on her neck in the morning sun. My gaze naturally locked onto her chest. Those breasts moved in an extraordinary way. They were huge breasts that bounced with every step, and while the sports bra tried desperately to contain them, they looked like G-cups. Seeing such large breasts move so naturally made my crotch react a little. Even though I am a virgin, my imagination runs wild.

She ran at the same pace as me and we exchanged a light nod. Her face had a youthful charm. She had her black hair in a ponytail, her breathing slightly labored, but her eyes sparkled. I quickly looked away, but inside I could not stop fantasizing about what those huge breasts would feel like to touch—soft and damp with sweat. We passed each other several times while running, but today I could not get her out of my mind.

After descending the hill and entering a flat section of the trail, she slowed down and stopped at a rest bench. I naturally matched her pace and stopped in the shade of a nearby tree. Catching my breath, I drank from my water bottle. She stretched in the same way. The autumn breeze rustled the leaves and a faint earthy scent tickled my nose. Gathering courage, I spoke to her.

"Good morning. You have a good pace this early. Do you run this route often?"

She turned around and smiled. Her cheeks flushed from sweat looked erotic.

"Yeah, I come here every day. How about you? I'm Natsuko, nice to meet you. I'm training for a marathon."

Natsuko. Even her name was cute. I introduced myself and sat next to her. The bench was slightly damp, and the morning dew felt cool against my rear.

"I'm Daiki. I work in fitness. Autumn is great for running, isn't it? Sweat dries faster than in summer."

The conversation flowed. Natsuko looked about 28 and was aiming to become a professional marathon runner. I shared stories about the gym and my morning jogging routine. Her huge breasts radiated presence right beside me. Just watching the cleavage that seemed ready to spill from her sports bra rise and fall with her breathing excited me. A faint scent of sweat mixed in and stimulated my nose. (I want to touch them soon… I want to squeeze those big breasts) My heart pounded loudly.

The break dragged on and Natsuko stood up. When she suggested "Shall we run one more time?" I nodded. Instead we took a slight detour deeper into the shade, walking along a path carpeted with fallen leaves. The autumn air felt refreshing and a sense of openness enveloped us. As we talked, the conversation turned to her running form, and I gave her coach-like advice. Natsuko smiled and said "Thanks. Let's try that out a bit," lightly touching my arm. The sensation sent electricity through me.

The shade grew deeper and we entered a secluded spot. We naturally stopped, our breaths drawing closer. My gaze fell to Natsuko's damp neck, her huge breasts right in front of me. The fabric of her bra clung with sweat, faintly outlining her nipples. (This is bad, I can't hold back anymore…) On impulse I reached out and pulled Natsuko's waist toward me.

"Eh, Daiki…?"

Natsuko's voice trembled slightly, but she did not resist. I embraced her and pressed my lips to hers in a deep kiss. Her tongue slid into my mouth and the sweet taste of saliva spread. The sound of the autumn breeze rustling the trees became our background music. My hands naturally stroked down her back and lifted the underside of her huge breasts from below. The sensation was warm and moist from post-run sweat, sinking in like a soft sponge. The volume of her G-cup breasts filled my palms.

(Wow, they're so big… These breasts are incredible)

I rolled up the hem of her sports bra and directly grabbed her huge breasts. The heavy mounds swayed, sweat droplets running between my fingers. Her nipples stood erect, and when I rolled them with my thumbs she let out a small "Ahh." The openness of being outdoors was irresistible. Leaning against a tree trunk, we continued kissing while pressing our bodies together. Through her leggings I could feel the heat of Natsuko's crotch. My cock was already rock hard inside my shorts, almost painful.

Natsuko wrapped her arms around my neck, breathing heavily. "Here…? It makes my heart race…"

I nodded and pulled her leggings down to her knees. Her pussy was exposed. Her pubic hair was light, glistening with sweat and morning dew. Her clit was plump and twitched when I touched it with my finger. Natsuko also removed my shorts and took hold of my cock. Her hand was warm, and the sensation of her slowly stroking me was intense. With her toned runner's hand she gently rubbed my tip.

"Daiki's is so hard… and hot…"

Her words made me unable to wait any longer. I sat her down at the base of the tree. While kneading her huge breasts with both hands I buried my face in her cleavage. The salty taste of sweat and the soft feel of breast flesh drove me wild. I sucked on her nipples with wet sounds. Her areolas were wide and pink, shining in the morning light. Panting, Natsuko whispered "More… suck harder." I eagerly took her nipples into my mouth and rolled them with my tongue. Sucking as if milk might come out excited me even more because it did not. (These breasts are mine… the fantasy I have always dreamed of is real)

Natsuko spread her pussy and invited me. I pressed my cock against her entrance. Her wet pussy slid over and swallowed my cock. The scent of earth and mingled body odor from sweat stimulated all my senses. With the cool autumn breeze caressing my rear, I began thrusting. With each thrust her huge breasts bounced against my chest. The soft, heavy sensation was irresistible. Her moans echoed among the trees. "Ah, Daiki… deeper… squeeze my breasts…"

I grabbed her huge breasts with both hands, digging my fingers in and kneading them. The breast flesh deformed and sweat scattered. My cock plunged deep into her pussy with wet sounds. Pressing her clit with my thumb, I increased speed. Natsuko's body trembled and she dug her nails into my back. Having such erotic sex outdoors was beyond a virgin's imagination. Sweat dripped from my forehead onto her huge breasts and slid down.

(I want it rougher… I want to make these huge tits shake)

Natsuko changed position and straddled me. Bringing her huge breasts close to my face in a riding position, she rocked her hips. Her pussy squeezed my cock and hot juices overflowed. From below I grabbed her huge breasts and bounced them up and down. When I pinched and pulled her nipples she cried "I'm coming…!" Her body convulsed and her pussy contracted. I reached my limit and released a large load inside her. The pulsing sensation of ejaculation made my cock tremble. Some semen splashed onto Natsuko's huge breasts, mixing with her pale skin.

Panting, we collapsed in the shade. Our sweat-soaked bodies touched as we basked in the afterglow. Autumn leaves fell gently, coloring the ground. Natsuko's huge breasts pressed against my chest, their soft weight comforting. She smiled and said "That was amazing… I've never felt this open in the morning." I nodded and kissed her again.

After finishing our run we exchanged contact information at the trail exit. Natsuko talked about her marathon training and praised my fitness knowledge. Noticing how similar our lifestyles were, we promised to meet regularly on this route. On the way home I took a shower and recalled today's sensations—the soft dampness of those huge breasts, the tightness of her pussy, the thrill of being outdoors. It felt like I had graduated from being a virgin, and morning jogging became something to look forward to.

After that I began meeting Natsuko every week on the morning trail. Sex in the shade after running, while squeezing her huge breasts, became our routine. Every time her G-cups swayed in the autumn breeze my fantasies grew even more. The openness of sweat and heavy breathing connected us. Even now, just remembering that sensation makes my cock throb.

(That morning encounter is something I will never forget…)
