Hi, i built two sex toys with cigar tube, in the first i have inserted a slim vibrating eletric motor and add a battery and switch on the top, it's similar to a classic vibrator but is a cigar tube !
Another cigar tube is built like a inflatable plug, with a slim vibrating eletric motor inside and three party balloons around the tube with a pump, like the pump of sfygomanometer, that swollen the balloons.
The second sex toy is very interesting !
I made a hole with the drill on the top of the cigar tube and two hole around it.
After i inserted the cigar tube in the party balloons, one at a time, as when you inserted the condom on your penis.
After with hotmelt i paste a vibrating motor in the cigar tube and the hose of the pump.
I seal the cigar tube with silicone, and made a switch for switch on the vibrating motor.
This is a picture that i have made with a graphic program for show to you the toy.
