That night, after Grandpa Kook’s birthday party turned into Tae’s slutty threesome debut with Kook and Yoongi, the house next door was quiet—but Namjoon couldn’t sleep a wink. He tossed and turned in bed beside Yuna, who slept peacefully, her elegant curves rising and falling with soft breaths. But Joon’s mind raced: his “innocent” baby girl Tae still wasn’t home from “helping” clean up at the old man’s place. It had been hours— what the hell was taking so long? Jealousy gnawed at him, memories of her clingy cuddles and midnight “soothing” sessions clashing with her recent absences. “Where’s my princess?” he muttered, his cock half-hard just thinking about her curvy body. Finally, unable to take it, he got up, slipping on shorts and a shirt, sneaking out without waking Yuna. “Gonna check on her,” he grumbled, heading across the yard to Kook’s house.
