I recently got the large Zeus torpedo plug I'm using with a PES box. I have to admit, it really plunges in and out like I'm really getting fucked up the ass really hard. I need that, my butt is always horny, just the way I'm made. I lie on my back with my legs at about a 90 degree bend, pushing my feet against the wall in the bathroom which has a really large mirror. It's really quite sexy to me, cum all over the place. Also roll on my side, do doggy, etc., etc. I put some pillows under my head so I can watch the whole thing in the mirror. My hole really bounces!
Here was the problem. I really experienced some ultra strong contractions, several times, came just short of sucking the entire plug right up my ass. I shut the box off and I relaxed. Did the same think the next day, I really like the strong contractions, reminded me of when I was a kid, put on one those vibrating fat shaker machines (my sisters) between my legs against my ass and over my cock, it was really hot, and I got very intense anal contractions.
I've read about problems with the Zeus large torpedo electro plug, no problem getting it up me, but the base is very small. I love the feel and did not want to get rid of it ... here is what I did for a DIY fix.
I got some large heavy copper wire from Home Depot, #8 solid copper wire in the electrical department, about 3 feet for good measure.
I bent the wire about the base of the plug about 3 times leaving each end sticking straight out. I then cut the ends off about 3 inches long from the base of the plug. Then, using pliers, I made a small loop in each end so the ends would not stick me. So, if you look at the plug now, it looks like a T. The copper wire just lies in my butt crack and the wrap around the base of the plug keeps if from getting sucked in. I tried it yesterday afternoon standing up just to see if it work, worked perfectly.
Tonight, I'll lie on the bathroom floor in front of the mirror and all and now I can let the ass contractions really take off. Damn, I'm hard just thinking about this.
I hope this DIY might help someone else with a similar problem. For the cost, about $29 for the large Zeus torpedo electro plug, it worked quite well.
I would take a picture of it, but I don't have access to my camera now.
