Y'know those black plastic bags they give you for your purchases at your local purveyor of leather and SM goods? Don't throw them away! Save'em!
After working your boys but with your favorite dildo or butt plug, toss the toy into one of the bags. That way, you won't get santorum all over and you don't have to interrupt the scene to clean up then.
