Double Blowjob Trainer prototype

Many requests have been emailed to me for a Double Blowjob Trainer! So I tried building a prototype for best friends Liz Rainbow and Blondie Fesser. Their collars are connected by springs. The idea is that one girl has to deepthroat her dildo to allow her friend a breathing pause. It’s a prototype so it needs some tweaking as the girls were stronger than I expected. Well, at least at the start. As soon as they got more tired, this new FoToRo invention started to work! Would you save your friend? Or pull the dildo into your friend’s throat so you can breathe? It’s a hard choice!
