skyplugging
Skyplugging. Like Skydiving, but instead of sometimes using a bungie cord, the participating individual instead uses an exceedingly long line of buttplugs, and must tighten their boipussi with enough force to offset the power of gravity, or else they'll surely meet an untimely demise on impact.
Me and Felix Argyle went skyplugging. Unfortunately, his boipussi was too loose after intercourse and he fell to his demise when each and every anal bead slipped out.
