This is from the novel....
I… I’ll help you…” Mu Hanzhang smoothed his lips. The red flush that had just retreated climbed up his handsome face again.
“Jun Qing…” Jing Shao looked at him in a pleasant surprise. Then, taking advantage of this opportunity before the other man backed out, he quickly took off his clothes and pulled the other’s slender and smooth hand to touch his own cock. Holding the person under his body who was shy and had the expression of ‘don’t look over at my face’, he found the two soft little nubs again and began to play with them once more.
After some time, it had gotten warm behind the red silk curtain, and it wasn’t known whether it was still this evening or already dawn.
After doing it over and over for close to two hours, Jing Shao held the person gasping for breath in his arms, and contentedly lay on the bed. From time to time, he gently stroked the other’s smooth and silky long hair.
Mu Hanzhang buried his face into Jing Shao’s broad chest, then feebly glared at him. Just then, this person had taken advantage of him not paying attention to launch a sneak attack again, causing the him who had just cum to once again cum with him. Now it felt like his whole body’s energy had been sucked out, and he sluggishly lay there, not wanting to move.

Sure. Here you go
