Another idea I had been tinkering with. I'm not sure why I originally decided Alister had to be comically hung, and tho I don't intend for that to ruin the fun between him or anyone I pair him with, I'm not above playing up the fact that almost everyone is intimidated by what's between his legs (even after multiple encounters) and will likely question if they're putting their lives at risk by bending over for him.
Of course, this is fantasy, so all they're gonna need a little lube and go-getter attitude and there won't be a need for an ER visit at the end of it all xD
