Hole in the Wall
You'll either need to be adventurous enough to cut/drill into a wall somewhere or else get a big piece of
plywood or drywall and cut a hole just big enough for his fully erect penis to fit through without touching
the sides. Get him on one side of the wall, you one the other. You'll find that the wall will add a certain
surreal touch to the experience - a sort of mystery blowjob.
