First things first, make sure wether he came or not

You suddenly grab a handful of his dark blond hair and yank it upward. Squinting from the pain, Andrew quickly propped himself on his arms and awkwardly got up on his knees. The movement **** your friend out of your brother's well-abused ass and made him fall back. As he lost balance off the bed, his feet barely caught the floor and he had to grab the desk behind him to steady himself.
Still pulling his hair you look your baby brother head to toes. As you do you quickly notice his small dick bouncing up in nervous spasms with a long line of cum still leaking from his dick-head, sliding down his shaft and along the center of of balls before dripping slowly. He seems to have cum plenty and/or many times. Looking down you see there's a large stain of fresh cum on your sheets where is sissy cock was rubbing. You guide him to the edge of the bed and then push his face right in the pool of his own slimy cum. The feeling of his warm, fresh sperm makes him whimper but you and your friend love the sight. Your friend takes a camera and snaps a couple of shots as you hold Andrew down. His well-fucked asshole is still gaping open, cum bubbling out and his dick is still twitching out of pure lust.
"Look at this little cum-slut! He came from getting **** senseless!"
Your friend laughs at the worthless sissy-bitch in front of you.
"You came all over my sheets you little shit! Clean it up while you're there! Eat your fucking dirty cum right now! You hear me?"
Andrew gasped a meek "Yes, Master" and started lapping at his cum.
"And keep that ass up!"
He nodded.
