It takes Jack a moment to move. He shivers, amazed by how empty, how vulnerable he feels without Poison's cock in him. He eases down onto his knees, more on all fours than up on his knees. It's the first time that Poison's told him to suck him when he's just been in his ass. Jack hesitates for a split second and then he leans in, sliding his mouth down over Poison's cock, eyelashes fluttering like he's being kissed.
