Upperdecker double blumpkin deluxe

One person sits on the toilet while the other person stands above him. The person sitting is giving a blowjob to the standing person while both are taking a shit.

I walked in the public restroom and caught my roommate and some stranger doing the upperdecker double blumpkin deluxe.
