Dean gasps out as his head is jerked back quickly. He knew he could either go with it and not choke or resist and have another ligature mark. He chose to move with it and yeah, so he was reminded who was in control. Still didn't mean he had to roll over and take it like an animal.

"Not your fucking dog." Dean hissed even as he was pinned to the mattress by his shoulders and a hand was roughly shoved into his pants cupping him with purpose. His teeth clenched together to stem any further sound that touch caused because he would have been ecstatic had it been Cas doing the touching. He also couldn't stop the way his body reacted, his cock twitching in Lucifer's hand at the sound of Castiel's voice being used. Lucifer had to know the reaction it would cause and as such would certainly take advantage of it.

Dean smirked slightly. Just think Luci, you have to wear a partially fallen Seraph to get Dean Winchester to even think about possibly responding favorably to your touch. If nothing else positive came of this...at least he could cling to the fact it was the visual and sounds of Cas making him react like this. Not the archangel.
