Lee Soonkyu heard the maknae's desperate pleas, but she wasn't finished yet.
"I am not finished yet baby.. with your 'punishment'."
"Please.. we should end this.. fast .." A raspy voice croaked in response.
"Nonsense.. you naughty girl, you still need your release, right?" Before even hearing a reply, Sunny increased her finger's speed, and also increased the strength of her sucking on the swollen nipple.
"Look, your nipples have swelled so much, and you leak so much juice, I think you are getting hornier by the day .. he he." Sunny continued to tease the younger girl.
She then looked up and saw her expression of ecstasy and her nipples swelling even more. And she felt her fingers being squeezed by the tightening pussy walls, and Sunny smiled even brighter. Increasing her speed, she pumped furiously now, and bit down on the sore and wet nipples, bringing pitched yells of "Ahhh... AHHH!!!"
Then she brought her other hand to the swollen clit and gave it a hard pinch.
"I'm... cumming! AHHHHHHHHHHHHHHHH!!!"

"AHHHHHHHHHHHHHHHH!" A muffled scream was heard, echoing through the dorm.
Tiffany and Hyoyeon looked on in excitement, as their precious maknae almost sank down to the floor; her knees were trembling madly, her back was arched and her thighs were clenched tightly. They saw her little fists knocking on the door, and they smiled at each other.
"Looks like the maknae will lose." Hyoyeon smirked.
"Sunny Unnie!! ... Please … hurry up! I.......I......" Seohyun gave one last, desperate plea, her voice trembling violently as she shouted.
And the bathroom door opened with a bang.
Lee Soonkyu stood in the doorway, with a tiny towel wrapped around her wet body. It was barely enough to cover her upper thighs, and her 37 inch, full and milky white boobs. She has a satisfied smile on her face, like a cat that just ate the canary. And behind her, was a dazed and panting Kwon Yuri. She too, was wet and naked except a tiny towel wrapped around her body. Her towel was even tinier, and it appeared to be wrapped around her body in a hurry. The bathroom behind was filled with a cloud of steam that slowly dissipated into the corridor.
Seohyun however, paid no attention to the smile on Sunny's face, neither did she see the dazed, orgasmic expression on Yuri's face. The moment Sunny took one step out, she slipped past the two girls into the steam-filled bathroom as if her life depended on it.
The next instant, as Sunny stepped further out of the room and pulling along Yuri by her hand, the door behind them slammed shut. "Thank you Sunny Unnie, Yuri unnie! My bladder was just about to exploded!" the muffled voice of the relieved maknae came from inside the bathroom.
"Awww , looks like Seobaby won, she lasted until they came out." Tiffany clapped and smiled happily like a proud mother.
Ignoring the two grinning spectators, Sunny pulled the still dazed Yuri along, passing the two on the couch. "Come on baby, let us continue this in the room, I still have more fun planned for the morning."
Yuri looked down in embarrassment, her face burning bright red as she obediently followed the grinning Sunny to their shared room.
As the two walked past to their room, Tiffany and Hyoyeon could not miss the leather-wrapped, steel handcuffs around both of Yuri's wrists, and the attached chain that Sunny was pulling Yuri along with. Seohyun did not see it due to the steam coming out from the room, and also because she was too focused on rushing into the bathroom to relieve her nearly exploding bladder.
Hyoyeon of course, could hardly keep her eyes from the bouncy, round melons nearly exploding from the tightly wrapped towel on Sunny, while Tiffany eyed Yuri's delectable ass and firm thighs from behind as the two horny girls swayed their way into the bedroom.
Yoona then appeared from her room, and watching the two girls enter their room to have more fun, she looked at the bathroom and asked, "So Seohyunnie lasted until Sunny unnie had her fun with Yuri unnie?"
"Yup, she has got strong bladder muscles alright." Hyoyeon remarked with a grin.
"Why doesn't she use the other bathroom instead?' Yoona asked again.
"Errmm, that's because Taeyeon and Sooyoung just entered there a short while ago. This bathroom was the maknae's best bet. You know how long those two crazy perverts can last when they get together." Tiffany replied with a hint of annoyance.
Yoona and Hyoyeon laughed when they heard this.
