Okay! Very rough idea here:

Not sure if I’m going for more the sensations of temperature play or the rush that comes with the perceived dangers of knife play but I think that with wrny it’d be a mix of both. Lyney’s got complete control of the fire when his hand lights aflame, it’s the spark of an idea that comes when he’s riding Wrio.

The warden looks at him curious yet never nervous. “Is now really a good time for a magic show?”

Lyney smirks, bringing his flaming fingers down just enough to caress the air above his stomach where his happy trail begins. The hair burns to ash where his finger hovers. “Who said it was a show?”

Wrio watches him as his hand inches up further from navel to neck, skin warmed just from the proximity. Then Lyney grins and pounces, hands around his neck, fire spreading from one hand to the next, yet the flame doesn’t burn, just warmth that teeters on being too much.

(Also Wrio getting off on the idea that Lyney could have ended him there and he would have just let him sjkejfguwsvbi)
