Closed Circuit

When a consenting adult human with a penis double fists anally and vaginally a consenting adult human with a vagina while the fistee blows the fister. i.e 69ing but with consensual double fisting ;)

Trenton: Did you hear that Tammy and I completed a closed circuit last night?

Jake: Really?? You got both fists in there? Wow man I’m impressed.

Trenton: It took a lot of prep but it was worth it at the end, all out of lube though…
