Cain got what he wanted and the instant he did, he didn't want it anymore. Being looked at like he was sexy and desired was a million times better. The compliment on his body and Ben's touches nourished him, smothering the angry, resentful part of him that had driven him to this moment. He let it die and embraced the way Ben was treating him, letting it bring him back to life, back to himself.
"Thank you," he accepted being told he had a good body graciously, his hands travelling down Ben's thighs and wrapping around his cock. It wasn't lubed and Cain set about changing that as his chest was caressed. "It's all yours, now," he added, thinking he sounded corny, willing his body to someone else but it was true. He was owned by Ben and Kerr, his body was theirs to do with whatever they wanted. Unfortunately/fortunately. He tossed the lube aside again when he was done coating his fingers and thumb with it.
Ben's purer treatment continued and in that entreaty, he saw again the man he'd got close to when they'd grieved Kerr together. Cain was so relieved to see that he was still in there, he nodded and complied eagerly. Stroking Ben with his right hand, he supported his weight on his left near Ben's shoulder. He didn't go to Ben's mouth straight away, he kissed his chest, tonguing his nipples before trailing his tongue over his pecs and up his throat. When he got to Ben's jaw, he kissed and nipped his way along it, not getting very far before Ben turned his head impatiently and kissed him again.
This kiss was different again, to Cain. It took him only a few moments to figure out why it was, because it was exactly the same as when he kissed Kerr. It was passion. Their kiss was firm but in an erotic way - tasting, plunging, sucking tongues - and gentle - slipping, sliding, brushing - in a way that got Cain's body singing with lust. His hips began to move of their own accord, pumping in time with his hand on Ben's cock and his lips on Ben; slow but building inexorably.
In trying to seduce Ben, he'd seduced himself and it was wonderful.
