You move out of the way, but Lucas sees your bulge

Your growing bulge scares you. You couldn't actually be liking this. You push yourself away from the fucking pair and manage to stand up. You were going to just walk out, but you suddenly wonder what Lucas's ripped body looks like when he really thrusting his cock hard into Mark.

You turn and get an eyeful of both of them. Lucas is standing tall. His toned, perfect body stands in contrast to Mark's child-like frame. But this only further emphasizes the size of the boy's thick cock which is bobbing underneath him, and slapping his flat belly with each thrust from Lucas.

You stare for a moment too long. Lucas looks over to you and smiles. "Enjoy the view over there, Peterson? Oh course you do. Look man, straight boy is sporting a big sexy bulge."

Mark looks up and licks his lips.
