Yes Miranda (where T-Bag hooks up with an incestuous brother/sister wanna be serial killer couple) and Don't Leave Me, Don't Let Go (where T-Bag has consensual sex with a chick and afterwards kills her). Both are by miss_mandy

There was one where T-Bag has a girlfriend who visits him after he is enjailed and he lies to her and tries to convince her that he didn't do it, but I completely forgot who wrote it. It was more like the beginning of a story anyway.
