I want to do it with 3 of my friends since it has 4 attachments.It would be hot to do a scene with 4 boys getting hooked up to the machine by a kinky femboy nurse.
This sounds very nice if a fellow is all alone AND is somewhere where the sound doesn't disturb the neighbors. If there was more than just myself, I would certainly want to suck all penises first. I wouldn't want for the machine to be so good that nobody wanted a blowjob!!!
