Yes

Mike stops his recollection of the threesome, looking down the hallway.

"We better check that out..." You say, and Mike nods at you.

The two of you head quickly down the hallway, but stop short when you hear short deep grunts, followed by the thudding of wood on wood. Every once and a while, there is an additional, higher grunt. "Oh fuck!" You hear after listening for a few seconds. You and Mike walk slower now, more carefully.

You reach the room where Tom had been sleeping, and the door is closed tight. The sound of the grunting and wood smacking back and forth is much louder now. Your heart is beating harder, and harder. Your face is flush, hot with blood. You notice Mike's is too.

"You little fucker..." You hear your father say clearly through the door. The deep grunts stop as he says this, and continue after. The wood on wood thudding continues.

"Ahh...gah, just fuck me...." You hear your brother Tom moan. "Ahhh.." he moans again, and again, and again.

You and Mike just stare at each other. Your father and your brother are definitely going at it behind the door. Before you can think much more, Mike pries the door open between wood thumps, and peers into the room.

You peer into the room with him, and are stunned when you see your brother sitting on top of your father's cock, the bedposts thudding into the wall rhythmically as your father's dick slides up and down your brother's asshole. Your brother is jerking himself at the same time.

Mike gives you a strange look and you notice both of you are quite aroused. He starts to speak.
