A ragged sound came from him when Sam kissed harder and Dean tugged at Sam's shirt more roughly, deciding Sam was actually a pretty good kisser. He was aggressive, dominant, and Dean was already into being pushed about by girls he was with, so this would... hopefully help. He just had to get over the whole incest thing...
Staggering back as he was pushed, Dean looked up at Sam with wide eyes, but the green in them sparkled a little bit with fire. He was definitely going to Hell again. He was way too turned on by this kid he raised. Worst life choices were about to be made, by both of them.
"Pushed me a little hard there, buddy boy," he murmured, his voice full of coercion and streaked through with lust.
