When an aeration pump, hose and stone are used to keep an gerbil or other small animal alive within the colon of a man. This increases the prostate stimulation time. Usually, battery powered bait aerator's are preferred because of compactness.
Rob: I got rats because they were cheaper than gerbils. You got the gerbil respirator.
George: I got this D cell powered bait aerator for $7.99, at Walmart.
Rob: Ah fuck, we forgot the tubes.
George: C'mon we're loose enough to go tubeless. You practically need vise grips to keep the little bastard in you long enough to cum.
Rob: Oh do you know me!
(Gay loving ensues.)
