Fitting in.

During the fight against the collectors Miranda and Shepard could help each other fit into their new lives so there wasn't much trouble with that, but this became much more difficult for the both of them when that mission ended. Miranda in Shepard's body was sent to jail while Shepard in Miranda's body soon left Cerberus and went into hiding while still keeping an eye on her new sister.

Somehow it was only then that the two really started to explore their new bodies, sexually speaking at least because in other ways they had gotten to know their new bodies very well during their travels. Miranda quickly found that while not nearly as hot as her original one, her new ass was much more sensitive, so much more even that it was now her favorite erogenous zone. Contrarily Shepard found that while extremely attractive most of Miranda's body wasn't nearly as sensitive as her own, but she derived an odd sense of pleasure from sucking on whatever she could get in her mouth. In her new body Shepard usually had something in her mouth, be it a pen, her fingers, or a dildo, but she hadn't thought to try actually having sec in her new body.

Shepard's not fucking in her new body lasted until she saved a young Asian woman from slavers trying to kidnap her, the girl was so enthusiastic in thanking her rescuer that she kissed 'Miranda' deeply. Later that day 'Miranda' was in a sixty-nine position where the girl ate her out passionately if somewhat unskillful while 'Miranda' gingerly kissed the seven inch cock she was stunned the girl had. Apparently the young woman Shepard rescued was a hermaphrodite, this lead to her discovering just how pleasurable it could be to give a blowjob in her new, orally obsessed body.
