Justin Buttplug Fic.

I'm in a porny mood and I want to re-read a fic I remember from quite a long time ago.

All I remember is that B/J are on a bus, or a subway maybe, (I think in NY) and they're heading back to the hotel from visiting an art gallery or something. Brian discovers that Justin's got a buttplug in and proceeds to press against it for the whole ride until Justin comes, right there in front of the oblivious passengers.

I think there is also a sequel that picks up back when they arrive at the hotel, but I'm not sure. (Maybe written by a different author?) Or maybe there is more than one story on this theme. I feel like I've read the plot before in a couple of seperate places. (I'm obviously a big fan of buttplug!Justin ;-))

Help please. Also, feel free to rec any other porny stories you may know of. Thanks!
