The sexual practice of connecting two erect penises together at the tip whilst a fully lubed, double sided 'sleeve' fleshlight is made to move along one participants shaft to the others, sliding back and forth from one base to the other (Mimicking the movement of a monorail going from one station to another, hence the name)
I want to try monorailing with my boyfriend, but I don't know if he'd be up for it
My boyfriend and I tried monorailing last night, it was one heck of an experience!
