Okay so you may be thinking a waterbottle wtf! my d*ck wont fit into that dont worry i thought the same thing so what you do is cut the water bottle to you penis size then where the sharp ends are where you just cut cover them with tape then put in the plastic baggy and wrap the zipping sides to the top and put some hot water in there then dump it out to make your fake vagina warm and then put your lube in it and go at it.
