[his hand had been insistently working on the lower half of Booker's dick that he couldn't get into his mouth, so he does notice the shift in anatomy... but only as an idle, distant afterthought. he lightly presses his fingers to them, curiously, but it's very brief and done right before he both pulls his mouth out and lets go of his cock.

every part of his body that he's aware of aches and burns now that the adrenaline rush is wearing off. he straightens up with a low, significantly less sexy groan, and it's then clear that the mess of Booker's cum is not limited to his clothes, but also seems to have gotten on some of his hair and, predictably, all over his face. Curtain appears unbothered by that, at least, as he absentmindedly licks his lips and then his fingers, after using them to start wiping at his face.

after a few seconds of that, he seems to think better and at last actually takes off his top. he makes use of the parts that are miraculously still untouched to wipe the rest of his face, and unceremoniously tosses it on the floor.

and then, finally, he looks at Booker's face.]
