Put a peeled banana up your ass put on a nice pair f underwear and go for a long walk in the hopes you can hold it in (must be at least 45 minutes)

Shove a banana up your ass, make your it stays there by putting sticky tape on your ass, yes sticky tape.

I like you dare so much that you have to do the same but with 2 bananas

Try this :

Wear reasonably loose underwear of your choice and duct tape the leg holes to your legs. Next up, fill the underwear to create a bulge resembling male genitals (cock and balls). This can be done by either wearing a strap-on underneath the underwear, or perhaps putting in a banana or a cucumber with some small fruits. The possibilities are endless. Once you are satisfied with how the bulge looks, dress up in clothing of your choice, but the bulge should be fairly visible. A reasonably tight pair of pants, shorts or a skirt would work the best.

Step2: check yourself in the mirror before going on. You should have a minor to major bulge now in between your legs, depending on how you chose to complete the first step. Once you are outside, go wherever you would normally go, but keep track of reactions that people have. This includes quick glances in your crotch area, surprised looks, maybe even disgusted looks, and more. Keep a track of who looked at the bulge more, men or women. This can be used for some research later. If someone asks you about it, you can explain the dare to them, and then offer to show them it. If they accept, take them somewhere private and either pull down your pants or lift up your skirt so they can take a nice look at the bulge. If they want to, you can let them feel you up. Keep track of different reactions to this as well.

Step3 (bonus): go to a club, and try to get a partner to dance, and then begin humping him or her. Alternatively, just walk up to someone and poke them with your crotch. Keep track of reactions here too.

Insert a peeled banana then poop it out and have a snack

Shove one down you back of under wear before bed and sleep in it

Leave the banana unpeeled and cut off anything scratchy. Deepthroat the banana, you only got one try. While it's in, mark the spot you managed to reach. Anything you didn't manage goes up your ass. Anything managed has to be turned into a sandwich. Pee on the finished sandwich before eating.

Video yourself peeling a banana with out your feet

For you try to stick 2 bananas in your ass and try to hold for 15 mins

Put a peeled banana in each of your socks and put them on. (You can wrap a small trash bag around each foot so you don't make a mess). Put on a pair of tighty whities and put in another peeled banana or two. Smash up the banana in your underwear until it's mush. Put on some sweatpants, shoes, shirt and walk or run for at least 30 min.

When you get back. Take as much of the banana mush from your socks and underwear as you can, and have it as a nice snack.
