We are actually pretty old school in lots of ways - having perfectly serviceable dicks to fuck with, hands to play with subs and other subs to suck whatever we want them to there is not really much need for machine play. That said of course we do it and some subs get really turned on by being fucked/milked and stimulated by machines. We use an adjustable (up, sideways and detachable like a drill) fuck machine, a tremblr and venus milking machines, a sybian (yes they do work well on boys) and various vibro (I will do a separate blog on electro at some point - which is not such a big thing for us).
I suppose the point about machines is that they just won't stop, they don't get tired or bored and will just keep going no matter what. This is good for what I call a timer challenge. Get the sub in whatever position you want - if using a fuck machine and a milker might I recommend a sit sling. Be careful lowering them to impale on the fuck machine. If just one of you get the sub to pull up on bars above their head and treat the impaling as a predicament test. They can control their own descent but of course cannot hold their weight forever so will have to lower themselves eventually. If two of you are Domming using straps is best - make sure to control the straps with both hands. Release the clasp with left and manage the lowering with right is my recommendation. It is a bit like abseiling - you will learn control. Be careful and take your time. However you do it once you have your sub hanging in the air and nicely impaled on your fuck machine attach your milker. I get this started and ask them how long they think they can last. Once we agree a time I show them a cooking timer which I set in front of them. No cheating here. Once the timer is set that is how long the machines stay on for. If they can't keep their shit together and cum before the time is up then tough. It stays on. If they don't cum - tough - time is up and their balls just have to stay full. Of course once the timer is going then I start to adjust the controls, increasing pace, suction, intensity etc.My goal is to get them to lose it and shoot their load with about a minute or so left on the clock - just enough to give them a taste of post orgasm torment.
It is possible with some subs to extract multiple loads - make sure they have agreed in advance because it is tough on them. Once they cum the milker needs to be at max speed for about 30 seconds post orgasm before reducing it right down and slowly building again. One very impressive sub we played with managed to cum 3 times in quick succession no break. It was total torment but he loved it - afterwards!!
Another nice variant on machine play is to tease a tied sub on a bondage board or in a sleepsack by suspending a vibro just within reach of the tip of their cock. They will have to work hard to keep in contact but keep still enough to get the stimulation. Of course letting them finish is entirely up to the Dom(me).
