B/J impregnate Lindsay the 'old-fashioned way' & evil Mel

[cowboystracker.livejournal.com]

I'm looking for a story wherein Brian has sex with Lindsay with the hope of getting her pregnant. Justin is actually in the room during all this. If I remember correctly he's rubbing Brian's back and kissing him. Mel is really cruel to Lindsay in this fic and tries to get sole/joint custody of the baby (I think it's Gus but I could be wrong) and claims to have impregnated Lindsay herself.

I checked the tags with Lindsay in them but nothing seemed familiar.

ETA: FOUND! It's 'Giant Steps' by Ashleigh. Link is in the comments.
