A story by CBlack on the TG Comics website (
http://tgcomics.com/cover.php?agree=0), has a pretty well done IB scene in chapter two. It starts on page 65 and goes to 67. Then in Episode 3 starting at page 23 due more to clothing and styling than anything else.

That's where the IB starts.
On a side note, the whole story is TG, and sort of reverse fmg in earlier chapters. (Whether that constitutes IB is up to you I guess, I sorta like toned women myself.)
