You and Yoon Bum have been dating recently. It started when you found him being picked on by a bunch of kids, mocking him. You were quick to defend him and knock the daylights out of the poor kids. After that ordeal you didn't bother with him anymore. Not until you felt like someone was watching you. It didn't take long till you found your little stalker. Oh and who would've guessed. There in the corner cowering away form an angered Y/N stood Yoon Bum.

"What the hell are you doing?" You sighed putting your fists down. Yoon Bum just looked at his hands and mumbled, blushing. You turned your head to listen "say again?"

"Uhm, I-I just wanted to uh s-say thank y-you for saving m-me," he squeaked out. You couldn't help yourself but chuckle at his cute behavior.

"Yeah, no prob," you were quick to go back to your cold face. Though that didn't go well as Yoon Bum continued to follow you once more. You let his little stalking game continue until you finally got annoyed. "So you gonna hang with me or nah?" Just those words made Yoon Bum blush and run off. But he came around.

It didn't take long till you started dating. Yoon Bum was known for 'taming the beast'. No one bothered him after that, since if they did they'd regret it the next day.

You and Yoon Bum have had such a nice life after you got his uncle arrested and he got to live with you. Of course with you both being, somewhat, healthy teenagers you got urges. Your sex life involved you being the dom and Yoon Bum being submissive. You were both fine with the rolls since Yoon Bum loved being taken care of and spoiled and you loving to take care of him and spoil him. Though some would say you had a lot of kinks no one out kinked Bum. This boy had such a dirty mind you were sometimes afraid to ask him what he was thinking. He once responded with "Being fucked over the counter hard," it just slipped out without him thinking. A few choking fits later and a madly embarrassed Yoon Bum, he seemed to have gotten his wish.

Though you guys have been trying new things there was something Yoon Bum was dying to try, something he saw on a video that got him crazy horny. It didn't take long before he got the opportunity.

You and Yoon Bum were smooshed against the trains door from how crowded it was. Yoon Bum being crushed against the window while you protected his back from any perverts watching or so he didn't get crushed to death, your bummie was a very fragile creature.

Yoon Bum was withering in front of you has his breathing was sharp and ragged.

"Bum, baby are you okay your heating up," you felt his forehead to which it was hot," are you sick you only breath like this during....," only then did it hit you how weird and distracted Bum had been. He was only this flustered while you guys are making love. You felt around for any signs of toy or pills. You knew how much Bum loved to tease you with his body, he always left little hints about what he wanted and what he was doing. You listened closely blocking out the sounds of the train tracks and people. And there it was a faint humming. You smirked as you rubbed around on his butt only to feel a small remote.

"Oh, was my little slut needy for mommy?" You showed the remote to Bum before playing with the settings. You went from high too low to the middle, changing the process to random.

YoonBum's knees buckled as he moaned out. You covered his mouth so you wouldn't get caught. He drooled on your hands as he pushed his ass against your crotch.

"Be quiet or everyone will hear you," you hushed out. Yoonbum only moaned out. You saw something leak from the front of his pants. "Oh, do you like that you slut," you chuckled "you like everyone watching you,". You grabbed his crotch. Yoon Bum sucked in a breath and starting grinding himself on you. You rubbed along his hips before you put your hands into his underwear and then groped his ass. Yoon Bum released a muffled moan as you stuck a finger in him. "I see you've already prepared for me, hm?" Yoon Bum nodded his head and gasped as you pushed the toy in him deeper. "Oh, y-yeah~ There right there p-please~," he moaned out. That attracted a lady's attention. She started at you both before blushing and nodding her head looking away. You chuckled as you put the toy in Bum to its highest. His whole body went stiff as he was about to release a high pitch moan. The toy had made direct contact with his prostate and god did he love it.

The conductors voice yelled out as Bum cried out as he came. Some people got off as more people got on. You waited until the train moved again, once it did you continued. Your hand made its way up Bums back to his chest. These were the times you were glad bum wore your clothes. As his little frame couldn't fill out your sweatshirt or jacket. So no one could see your hands. You felt his perked buds as he stiffened yet again. You knew how sensitive Bum was there so of course your gonna mess with him. "W-wait no there, p-please," he squeaked. "What? I thought you wanted this, isn't that why you put in the vibrator?" You kissed his neck. "N-no....mayb-be," he mumbled. You knew Bum loved playing hard to get, it made him feel wanted as you would stop at nothing to get him. A small smile creeped on his face as you kissed his cheek and nuzzled your head into his neck. He moaned once again as a certain bump made your current fingers go deeper in his ass and push the vibrating ball deeper. He felt his dick rub against the front of his pants, that were currently sticky with cum. He felt dirty and did he love it. You groaned as you felt Bum rub himself against your private area. He bit his lip as he felt you squeeze his nipple and rub inside of him at the same time. He looked at you before his eyed rolled back and he let out a silent scream as you jabbed his prostate. "Oh, f-fuck I-I can't I'm s-so-," his hips stuttered as he put his fingers in his mouth as he started to bounce on your fingers. His moans turned muffled as he couldn't hold himself anymore and grabbed onto your arms. "C-cumming I-I'm g-gonna gonna c-mmmnn," he couldn't finish his sentence as he shook, "cumminnnggggg ahhhnnggg," his hand that was in his mouth now gripped onto your shoulder as he spasmed and shook with his orgasm. Drool leaked down his mouth and his eyes crossed. He looked like he was in complete bliss. He slid down to the floor as he knees had given out on him. You had to pick him up so he didn't touch the floor. "D-did you just have a dry orgasm?" You stated more then asked. Bum could barely think straight as his mind felt fuzzy. He always ended up like this once he had dry orgasms along with when he squirted. You didn't know guys could do that but Bum just keeps surprising you.

You took tissues out of your bag as you wiped him clean. You lifted him up as his legs went around your waist and his arms around your neck. "Felt good, baby?" You asked. Even after all the dirty things you just did your Bummie still looks adorable. "Amazing, m-mommy," you chuckled at the nickname as he blushed and put his face in your hair.
