anal towing 

Anal towing occurs when two sexual partners link themselves at the anus, typically through anal beads. Both participants then tighten their rectums around the beads creating a firm grasp, while the dominant pulls the submissive as s/he crawls across the floor.

My girlfriend and I attempted anal towing last night - but we only made it a few feet before I lost the rig.

The subtle art of placing ones crusty toes up the anus of a partner or themselves (usually a gymnast)

“Hey Bella come finger me”
“No Myla you’re too far away from my hands let’s try anal toeing it’s more convenient”
