obviously you should have double bed room and put both characters in it when they show up for a massage.
lol, SS changed since I posted; am referring to the female workers one. Eg. smpl6 and 5, 9 and 10 respectively.
Ps. Shoulda inferred as much, since that I wouldn't be talking about the 14th, since that wasn't a scene & the 13th one
was explained AFAIR is self-explanatory -.-
Edit: Oh, right, and can be auto-ed for it, so can achieve it w/o knowledge or reference.
Edit. Though, I never really tried pairing the guy and gal massuer to a room, just sent them wherever, so maybe I should try.
