Thanks to everyone for all their great posts and all the variations on this topic. I had never considered bananas before and stumbled upon this topic the other day on another site. I had the house to myself on Monday and figured I would give it a try. I used the liquid glycerin suppos followed by 4 half bananas lubed with glycerin and then a tampon as a plug as recommended earlier in this thread and on other sites. I really enjoy enemas/suppositories and challenging my ability to retain them so this sounded intriguing. Also, I'd never tried the liquid glycerin suppos before so that sounded like fun also.
I purchased 6 semi-ripe bananas and a 4 pack of fleet liquid glycerin suppositories, placed 2 in the freezer to firm them up and gave myself an enema so I'd be cleaned out. I waited about 40 minutes after the enema and got everything ready. I took the bananas out of the freezer, peeled and cut them in half and placed them in a bowl with two more halves. (I figured I would start with 3 bananas as the recommended 4 seemed like a lot.) I used some vaseline and astroglide to finger my bum hole and get it well lubed and ready. I squirted two of the liquid suppos onto the bananas to lube them up and squirted the other two up my bum. Now it was time to insert the bananas and I was literally shaking with excitement. It's been awhile since anal play had me this excited.
I slowly inserted one of the cold banana halves into my bum. It went in easily and felt great. I followed with another and then another, slowly pushing them in. It was so enjoyable and I took my time, pushing them in slowly so they would push the other ones further up without causing any pain. By the time I got to the third banana I was getting full but still OK. After I inserted halves 5 and 6 I was really full but in no pain so I thought I would go for the 4th banana that I had set aside. I quickly peeled it, broke it in half and rolled the halves around in the bowl with the excess glycerin. The next half went in fairly easily but as I was getting ready to put the last one in I was having trouble holding them in. I quickly placed the last half against my anus and started pushing it in to stem the tide so to speak. I was able to get it in pretty easily but they definitely wanted to come out. My bum hole was still partially open so I had to use a couple fingers to push the mushy banana end past my sphincter. I was definitely really full at this point.
I had the tampon ready and used it to mop up the last of the glycerin and then pushed it into my bum hole. I could feel it pushing into the banana mush ready to come out of my bum. I got the tampon in but the urge to expel the whole mess was overwhelming me. I laid on my side for a minute holding the tampon in and regaining control. I was able to settle down after a couple minutes and figured I would clean up the banana peels and other stuff I had assembled and get rid of them while I held the bananas. The urge to go was incredible. I'm very good at holding enemas and have always been able to maintain control but this was something of another magnitude. I really thought I might lose control and have an accident in my house. Once I had mostly cleaned up I thought I would lay down and try to regain some measure of control. I laid on my bed with a small towel under me but I was really having trouble maintaining control.
Unlike an enema where I'll have abdominal cramps but they pass rather quickly, the experience here wasn't really crampy but instead there were waves of an overwhelming urge to expel the bananas and glycerin. They would settle down and become manageable for 20 or 30 seconds and then return stronger than ever, although never going away completely. I didn't lay on the bed for very long as I was afraid I'd lose control all over the bed and have a hard time explaining it to my wife so I headed to the bathroom and laid down in the tub. By now I really thought I was going to lose it but I was at least somewhere that I could clean up. I decided to try and relax and if it I let loose in the tub so be it. However, the tampon had now swelled and was doing it's job of plugging me up. I had this incredible urge to go but I resisted pushing but didn't really try to hold it in either. I kept expecting it all to explode out my bum but the tampon was holding it in. After several more surges I just couldn't take it anymore and moved to the toilet. (I'm not into diapers or expelling in the tub, although I may give it a try with bananas.) After a couple more waves of extraordinary urges I could feel my bum hole opening and the tampon started coming out. It finally flew out along with a couple banana halves then followed by a couple more. The urge to go was still incredible and the rest of the bananas came flying out about 15 seconds later. I've never felt so relieved in my life. I then started urinating and the urge to go took some time to subside.
I absolutely loved this experience and can't wait to try different variations. It took a couple hours for my bowels to settle down but no different than a large enema. I've never had this much trouble maintaining control. I've gone out in public in the past while holding a large enema without incident but there's no way I could do that in this scenario. I don't know if it was the bananas, glycerin or the combination but it was so much fun, especially inserting all those bananas and trying to hold them in. I probably only lasted about 15 minutes but it seemed like an eternity.
Sorry for the long post but if you haven't shoved a banana or two up your bum you should give it a try. I love reading everyone's stories on this site so i thought I would share one of mine.
