If you have multiple bananas, peel them all. Before proceeding, start by stretching your ass out with a dildo or butt plug. Once finished,carefully slide one of the peeled bananas into your ass, then carefully push it out of your ass using your anal muscles. After that, slide the first banana back into your ass and then push a second in, then a third, a forth, then as many as you can fit. Let me know how it goes!
