The Weight of Possession

This wasn't something you did in a dorm where Gang-bin and Teo were almost certainly staying. Yusom's face flushed crimson with embarrassment and humiliation.

Could he have asked her out with this in mind?

For a moment, Yusom regretted the past when she'd called him oppa, and even more, the fluttering heart she'd felt when she thought he was confessing.

"Hush, stay still."

Eun-geon easily subdued Yusom's resistance, his eyes carefully scanning her body. His gaze wasn't just focused on her breasts. He meticulously checked her stomach and sides. Thankfully, there were no bruises or wounds.

As he pulled her blouse further up, Yusom's breasts, clad in lace bra, were fully exposed. Her clean, white skin showed no signs of sex—no kiss marks, no bite marks, nothing. At least she hadn't been with another man since they'd been together, and the relief lifted his mood considerably.

"Why, why are you doing this, seriously."

Yusom tried to pull her clothes down, but it wasn't easy. Afraid she might tear her blouse, she couldn't push Eun-geon's hands away. It was a cherished piece, an expensive item she'd splurged on, which made it worse.

"I'm checking if you rolled around with some other bastard."

Every time Eun-geon's hand touched her, Yusom's skin trembled sensitively. He figured it hadn't been days since, but he couldn't be sure. Eun-geon suddenly squeezed Yusom's breast.

Eun-geon had been confused after sleeping with Yusom, but he'd decided to date her to protect her. The problem was that the girl he'd watched grow up since childhood had turned into quite the pervert. At 25, in the prime of her sexual desire. If he didn't properly satisfy Yusom's arousal, he worried she might go and throw herself at someone else, so he had to start with restraint.

"What do you think makes breasts grow?"

Yusom was speechless at the absurd question. As the rough man's hand gripped her soft, fatty breasts, a pleasure different from touching herself spread through her. Eun-geon's palms were rough. As befitting an athlete, his skin was thick, with calluses from daily weightlifting. His rough palm brushed over Yusom's sensitive nipples, making the tips stand stiffly, as if screaming.

"…Mmm."

Eun-geon's touch was unpredictable, so she couldn't help but react sensitively. She should tell him to stop as he kneaded and played with her breasts, but the words wouldn't come. Despite his rough nature, Eun-geon's fingers were straight like his spine. The knuckles that protruded in the middle were coarse, but overall, it was a pretty hand. His short nails were neatly trimmed into crescent shapes. The thick veins bulging from his knuckles to his wrists made Yusom keep staring at his hands.

So athletes have veins that bulge like that.

Yusom gradually shifted into spectator mode, watching her own breasts being kneaded. Due to her research, she often found herself observing the human body, albeit unwillingly. Nude models were harder to find than others. They needed to pay them, gather several people, and since not many could stand naked in front of others, recruitment was difficult. But nowadays, it was easy to see people with very attractive bodies in webtoons and movies. Everyone's breasts differed in weight, sag, nipple color, and erection state. Thus, Yusom felt even this situation was like studying material, so she let Eun-geon do as he pleased, thinking just a little more.

"How much have you kneaded them yourself that they're so soft and muscle-free?"

Since everyone's mammary tissue density, subcutaneous fat thickness, and skin elasticity differ, the texture varied accordingly. Some felt firm due to elasticity, others softer and squishier from thicker fat layers. Yusom's breasts were soft like marshmallows. She'd vaguely heard that larger breasts felt like this, and hers were the case.

"…Ah, mmm! No, they've always been like this."

Eun-geon found Yusom's embarrassed face, as if talking about masturbation was taboo even after they'd already done it, quite satisfying. The texture was such that he didn't think he'd tire of touching them. Yusom had a narrow chest but large breasts. Her thin body had fat only on her breasts. As she panted slightly, her slender ribs became clearly visible.

To heighten Yusom's arousal, Eun-geon supported her lower breasts and shook them. They swayed attractively, pink nipples trembling in the air. Whether it felt good, goosebumps rose on Yusom's skin.

"Why are you making these stand up again?"

At Yusom's transparent reaction, Eun-geon couldn't hide his smile. Fully erect, her nipples were thicker, good for sucking, unlike her innocent face. The contrast was lewd, so Eun-geon started circling Yusom's nipples with his finger.

"Oppa, why, keep… huff, only that part…!"

The kneaded nipples rubbed against Eun-geon's fingers, creating friction. Yusom bit her lips to stifle the moans bursting out, but it wasn't enough. Her nipples, softened by Eun-geon's heat, were pressed and stiffened repeatedly, as if sticking to his fingerprints.

"Ah… mmm, hmmm."

It was embarrassing enough to show her breasts to the oppa she'd known since childhood, but entrusting her especially sensitive erogenous zones made her feel ashamed. But amidst this, Yusom had other thoughts.

This kind of persistent breast play was a common trope in 19+ webtoons.

...So sex is all about experience, huh.

Yusom was entranced, just as depicted in webtoons. Instead of hastily kneading or painfully pinching her nipples, Eun-geon slowly observed her reactions, gradually adjusting the intensity.

"You've got the talent to climax from your breasts."

...That's actually possible? It was an episode that appeared in every Korean webtoon and Japanese manga Yusom had read. But not many women could feel orgasm from just their breasts. Yusom had tried a few times but had never reached climax.

"They say if a woman can't feel it through her nipples, you can damage the epidermis. Suck them until it hurts, or something."

Like sanding down, after scraping the sensitive nipple epidermis, the skin regenerates. There was also a method of stimulating the blood vessels and fine nerves repeatedly to awaken sensation. If you keep sucking with your fingers, they get worn out, so sensitive, soft nipples would probably get damaged quickly.

Eun-geon grabbed both of Yusom's breasts with one hand. Two nipples were poking out tightly between his fingers.

"Mmm… haa, my breasts, they're stretching…!"

With that posture, he gently pulled, and like a docile milk cow, her stretched breasts followed toward Eun-geon's body. Her skin felt taut, which was strange. But if she didn't want her nipples to tear off, she had to follow wherever Eun-geon pulled. It was a lewd, obscene scene. Yusom realized for the first time that a woman's breasts could be handled like this.

"I'm doing this service because you like having your breasts messed with."
