Xiao Xingchen watches the way that Song Lan's lips part, fascinated with the way his fingers could make his friend react.

No sooner does he think that when Song Lan's finger brushes against his nipple, his body jolting in response. His eyes widen and he gasps, and he's shocked that such a brief touch there could make him react so suddenly and... obviously. His face flushes a shade of red deeper, more from embarrassment at himself than the touch itself. Never has his body really reacted this way to anything, and so he doesn't know what to think of it. Yet... it doesn't deter him from wanting more.

Slowly, he rolls his hips back against Song Lan's thigh. The pressure eases the hot, uneasy tension within him, so he does it again, harder this time. His head tilts back and he moans softly, eyes lidded and hazy. He reaches around Song Lan's back, fingers gripping his outer robe for a sort of grounding as he starts to move in a rhythm.
