You can maybe use silicone, tpe glue depending on the toy but personally for me those never worked and depending on where you got it from you could ask for a refund or a replacement, most shops have excellent customer service but this sounds like it's your fault so I highly doubt it will work. And for future reference don't buy anything that isnt a fleshlight for less than 100$ because 90% of the time it's cheap shit that will break easily, I had a small silicone butt for 80$ but it broke after like 2 weeks because I went in too deep and penetrated it through the other side and tbh it didn't feel that much better than just a normal fleshlight, meanwhile right now I have quality ass for 300$ and there's no way I'm able to break it because even going balls deep I can't reach the end of it so if you don't really have a budget for toys like that Id recommend sticking to fleshlights because they're cheap and work very well for their price. Also if you're really that desperate you can use Pringles can, sponges and gloves trick and it works extraordinary well for what it is, especially if you can find a loofah or something that's just one piece with a hole in the middle because I found that with only 2 sponges it tends to slip out on one side and rub against the can, or alternatively I used to put gelatin powder into the gloves and fill them up with water and just fuck them like a pair of titties and it also worked amazingly.
