Rope tight your balls and attach the banana in order it reaches your knee level standing. Put the rope around the middle of banana for an horizontal position while standing.Then just admire my goddess beauty and make a hole with two fingers into the grapefruit and get hard.
Try to put your dick inside the hole, use lube if needed and start walking around your room. You can stroke your cock with the grape only if the banana don't touch your knees. When the banana touch one, you have to stop and and to put it into your ass, use lube.
