When they first started learning to fuck, Sammy was too shy to ride Dean.
Then one night, Dean was thrusting into him with abandon. And just as his little brother’s body started to quiver with approaching release, Dean pulled him onto his lap so Sammy could grind down on his cock till he came.
Sammy yelped, suddenly all exposed to his brother but too far gone to care.
Dean reached up to cup his face as encouragement and comfort.
“Yeah baby boy, just like that, fuck just like…do’n so well for me, so proud of you”
