BDSM
U spit it out all last time...
Although I prefer to force it out of you by hand, then make sure you swallow every drop, even if I have to hold your nose shut to get you to open your mouth...but then, you will gladly swallow it for me, won't you??
Using a machine takes away some of MY fun, and that's definitelly NO fun
