Chapter 40: 18+
From the tip of Hongju’s untouched cock, thick, cloudy fluid dripped out in slow spurts. Watching his rumpled T-shirt get stained only made the muscles in Mu-gyeong’s thigh tighten, his lower abdomen tingling. At the edge of climax, Mu-gyeong let go of Hongju’s slender throat and began to pound into him violently. He fixed his gaze on Hongju’s face, now flushed and panting raggedly.
"Haah, haah."
"Nnngh, ah, hhh..."
His eyes were wet and red. He couldn’t even close them—his thin body shivered and bounced with every thrust. As it did, the cum pooling on his flat stomach trickled down to stain the blanket beneath him.
It wasn’t anything particularly special. So why did it feel so damn obscene? Mu-gyeong bit down on the inside of his cheek as he came. He stayed buried inside, releasing everything into him, and Hongju trembled as he instinctively covered his lower abdomen with shaking hands. His fingertips brushed against the cum leaking out.
"Gu Hongju."
Even as he came, Mu-gyeong kept moving his hips, pushing in deep. He tapped Hongju’s bruised cheek with the flat of his hand.
"Nngh, mmph."
The dark eyes that had been fixed on the ceiling slowly shifted to meet his. For the first time, those usually dry, emotionless eyes flickered with something—though it was a messy mix of pleasure and fear, it was something human.
"That’s way better."
Muttering with a faint smile, Mu-gyeong gave a subtle thrust that sent a tremor through Hongju. The sensation under his skin made him dig his nails into his belly, scratching at the prickling heat. Mu-gyeong pulled out slowly, withdrawing the cock that had been stirring deep inside. Holding the shaft, he flicked the tip against Hongju’s scrotum, shaking out the last of his arousal.
The reddened, twitching entrance pulsed and spat out globs of thick semen. Breathing heavily, Mu-gyeong dipped his fingers into the runoff and pushed it back in. He repeated this a few times, and the entrance soon became coated in sticky, white foam.
