Items:
Funnel
Cooking oil
Option one most of the times it will work: One vibrating cockring, bulletvibe or egg remote controlled with wire or wireless both are fine, wire is more fun though explenation will follow.
Option one with a twist (works everytime: add an Vibrating buttplugs explenation will follow
A chair or something else to rest you're feet on which you can lie under with the head.
It's just a more comfortable legs over head variant.
The Setup written from the male perspective.
Well it's a Cum eating scenario, but instead of having to jerk yourself, you will get some "help"
first of all you have to get hard, and perhaps add an cockring to keep the erection.
now put on the vibrating cockring on the cockhead just below the cockhead on the front, or other vibrating thing if you don't have a vibrating cockring and fasten it with a normal rubber cockring or a tight condom with a hole in the end (put the condom on first and now insert the Vibrating bulb for instance in the condom so that it lays right on top of the small piece of flesh on the front of the cock the one that is so freaking sensitive, The Frenulum I belive it's called.
Now the idea is that you now have a cockhead with some sort of vibrating thing on front of the top, just below the glans/cockhead, if you try to turn on the vibrating power now you will feel it vibrate.
Now take the funnel and coat the inside with cocking oile, it will make sure nothing stick to the sides.
Lie down under the chair or table, legs over your head, is the same position that you know, but you just have some place to rest the legs a bit.
The cock is pointing towards the face and mouth so insert the funnel in the mouth and turn on the vibrating cockring device.
The special place that will be stimulated on the cock will make one cum pretty quick, and if not then just start by inserting an vibrating buttplug and turn on the power of both of them, it is impossible to hold back now, and soon you will Cum, it will flow down in the funnel, and directly to the mouth, no way of avoiding it.
combine it with some mild selfbondage, and if you're feeling really creative hook up the two vibrators to a electronic timer (just connect the battery connector from the wired vibrator to an PSU that can convert down to the voltage for the Vibrator, and connect that to a timer, so that you just have to lay there tied up and wait for it to happend.
Regard selfbondage you can use these amazing little things, that are a ton of fun to play with :)
