The bucking movement takes him a little offguard, his eyes widening a bit as he coughs a little. Huaisang doesn't pull back, however, instead settling his elbows on Jiang Cheng's hips to pin them in place. He begins to slowly suck on the head of the other boy's cock, continuing to run his tongue all over and around it as is mapping out new territory.

Once he's gotten comfortable enough with this much, Huaisang takes more of him in, one hand curling and gripping Jiang Cheng firmly by the base, spurred on by that moan. His own length is plenty hard as it presses against the other's body, the sensation of it encouraging pleasured sounds of his own.
