When a male or female is asleep beside you, you stick your forefinger inside their anal gland (with no lube) and see how many knuckles you can get in before they jump. Knuckle depth can be measured by the shit stain on your finger.
Male
Last night Liam passed out at the party! You'll never guess what happened, Joey have him a Chocolate Finger Puppet and got third knuckle!

Female
Arnold's misses fell asleep watching Netflix facing him. It was a prime opportunity for a Chocolate Finger Puppet but he had to improvise with a reach around.

Like a rusty trombone, but somewhat straighter. Performing anilingus on your woman whilst diddling her vaginal canal. Classy move, and lets her know hepatitis ain't no thing.
Although I enjoyed that Rusty Finger Puppet last night, you might want to get a blood test.

Sexual maneuver where you insert your index finger in the girl's anus with your palm up. Using the other hand, spread her vag lips. Now push your finger up past the taint so that a "pink finger puppet" comes out of the spread lips. Make puppet dance and sing as necessary.
