Spinter’s third law

Squirting 1-2 spritzes of lube (any flavour or un flavoured) into a zip loc sandwich baggie and using it to jerk off with, simply close the bag and discard it in the trash can when you are finished.

Super horny after seeing your sister mop the floor, do you mind if I go to the shitter and perform Spinter’s third law on myself
