Stepbrothers Trent Marx and Mark Something are in their bedroom, and Mark is feeling bored. Trent suggests they play a dare game, and things quickly escalate as Mark dares Trent to kiss his butt. Trent completes his dare, then counters by daring Mark to suck his dick. A moment later, Mark is sucking and slurping on his stepbrother's dick, but he then stops to dare Trent to lick his ass. The horny brother bends over and offers up his butt, and Trent dives right in to give his brother's tight hole a deep rimming.
The next dare they suggest is that Trent puts his dick inside of his brother's ass, so he slides his raw cock right inside and pounds his brother from behind. Mark flips over onto his back so he can look at his brother as he takes his dick. He strokes his own boner as he watches Trent pound his hole, then sits on Trent's dick to ride it before they go back to missionary. The horny brothers then jerk off and both cum at the exact same time, with Mark blowing a massive load that shoots right tup and hits him in the eye!
