Leave her be. And go to your room.

You decide to leave Claire where you left her but not before kissing Claire and giving her nipples one last pinch,which causes Claire to moan a bit. You finally start go to your room savoring how different Claire's Lips tasted using Ashley's mouth. You enter your room and lock the door,you then unbutton your light blue blouse and see that your wearing a cute pink bra and you lift up your skirt to reveal matching panties. You then proceed to strip down to your undergarments,you then stand in front of the mirror and marvel at how gorgeous your sister looks wearing only her bra and panties. You spend several minutes admiring all of Ashley's curves and then you start to knead your breasts,while watching yours sisters image do the same in the mirror. Despite them being smaller Ashley's...no your breasts, are much more sensitive then Claire's.Even though your only groping your breasts though your bra,you cant stop moaning as a electric feeling(which you can only assume is pleasure) courses though your stolen body.Despite being your voice now,Ashley's moans startle you because you've never heard your sister sound so...Sexual .You finally slide your hand into your bra and try pinching your nipples which results in even stronger bolts of pleasure racking though your body,which causes you to start moaning even louder. As you continue play with your nipples your your panties start to feel wet. Almost automatically your left hand works its way down to your vagina and by instinct you shove a finger in your clit causing you to fall to the floor in ecstacy as you continue to finger your clit you lean forward and grab your right breast and you start sucking on it. Which causes the most intense pleasure you've felt yetrack though your body. This continues for several minutes and as you continue you feel some feeling move from your back going to your vagina,as it comes closer you begin to moan even louder and with a scream you orgasm,your juices on the floor and on the panties you were still wearing. Tired from your first female orgasm you realize you can never truly go to being a guy after experiencing this. At the same time,something flashed though your mind and you realize you can make a body yours permanently and can gain all of that persons memories,as well as access their personality at will and be able to still use your possession powers but it comes at the cost of permanently destroying your previous form and it will alter history to think you have always been Ashley or whomever you decide to use it on. Apart of you considers fully becoming Ashley, but that same part of you from earlier doesn't want to do that to your sister. Which will you do? Permanently become your sister Ashley or find someone else to become your new form.
