Dick Tunneling

When two guys put their dicks side by side facing opposite ways and interlock their hands and jerk each other off at the same time.

Omg did you see Ron and Don dick tunneling last night? It was seriously one of the hottest things I’ve ever saw. I’m going to be jerking it to that image for a long time.

Tunnel sand

Tunnel sand is a type of sand that a railway/railroad tunnel will produce organically. In the past, tunnel sand has proven to be quite explosive in nature which is triggered by the act of a locomotive entering any tunnel that is producing tunnel sand. Tunnel sand is also the type of sand that is widely used in children's sandboxes in playgrounds.

Gee whizz, I sure hope this tunnel sand doesn't explode.
