Claire

You spin around, half expecting two crumpled mess of skins that was once your sister and her friend on the floor, but you are only greeted by their smiling faces.

''Thanks for having us around, Mrs. O'Neill,'' Katie beams at you. She's always a cutie, both Erna's and your memories tell you, and she has the face and features to go with that attitude too.

''You're welcome, dear.'' you reply.

''Well,'' Trish suddenly butts into the conversation, ''Katie, how about if we get things ready upstairs. We'll bring this oaf to do the heavy lifting for us.'' she motions to Nick. ''And Claire could stay here with mom and prepare us some snacks.''

Your eyes dart around, Jimmy's really moving things quickly, you haven't even got time to decide.

''Wait, what?!'', Nick exclaims, before he sighs, ''Fine.'', and he takes the girls' luggage from their hands, ''Where should I bring these to?'', he tries to suppress a knowing smile, but fails. Never a good actor your brother.

''Go on mom.'', Trish gives you a nudge, before she leads Nick and Katie upstairs, leaving you flabbergasted.

You rummage around the kitchen, opening and closing cabinet doors methodically to gather snacks and drinks. There aren't many scattered around, but the ones you found, you put on the table for Claire to select.

''I think the two of you might like this, and this.'', you set aside some mini chocolate cookies and low fat crisps, which you know Claire likes.

''It's as if you read my mind, Mrs. O'Neill,'' Claire says quietly and looks at you.

Your sister has a rather disturbing aspect of her personality sometimes. She would say things or act mysteriously, as if she knows something was up. That appearing trick she pulled earlier definitely caught you off-guard.

''Erm,'' you clear your throat, ''Trish likes them too.''

''Still,'' Claire mumbles, ''I'm not Trish, though.''

Sometimes you wonder how Katie and Claire are friends, considering their sometimes opposing personality.

Just as you are about to say something else, you are surprised by the sight of Trish and Katie entering the kitchen. Katie in a pair of matching bra and panties and Trish swapping her sports jacket for a matching tight nightwear top and matching short bottom. Trish whips out the black pen and zaps Claire.

''Aww, my little bro is now a sis.'', Trish says with a smirk on her face.

''Wait, '' you stutter, adjusting to hearing a different voice coming out from your throat, ''Is that Nick in there?'', you point at Trish.

''Yep,'' comes the reply

''Watch out!'' you hear Katie exclaims as she zaps Trish with the brown pen.

Trish swoons for a bit, but when she steadies herself, a half smile curls on her face, ''But it's better if you call me Trish.'' in a smooth motion she takes off her top, letting you and Katie takes in the sight of her perky breasts. ''They're so firm,'' her attention is diverted to her bosom as she cups both of them in their hand, then one of her hand snakes down her body, before disappearing underneath the short bottom that she wears. Moments later a small moan escapes from her lips, followed by another.

''Oh, wow.'' Trish looks up at you, her face flushed.

''David.'', you hear a familiar voice shouts before waves and waves of memories. Claire's. You realise that Katie just zapped you with the brown pen. When your senses return to you, you see Katie zaps herself with the brown pen too.

''They're so round,'' Trish whispers and you shudder as suddenly you feel hands cupping your breasts and the feeling of two fleshy mounds pressed against your back.

''It's our sister!'', you struggle to break away from her.

''But I don't have a sister, remember?'', Trish speaks, you feel one of her hand moving south and you know you've got to get away.

''Fuck off, it's our sis','' somehow, you get your elbow between your back and her stomach and pushes her off.

''Hey, I don't hear you complaining when you were in mom, and I certainly don't need you to ruin this by giving me guilt trips.'', Trish raises her voice at you, ''If you don't want to join us, then you're free to go home, right?'', she looks at Katie, as if looking for her support.

''Now, now.'', Katie stands between you and Trish, ''I'm sure David's just a bit uncomfortable,'' she turns to you, ''Do you want to swap? You can be Katie or Trish again if you want to.''

''It's just... too weird.'', your breath is ragged. You try not to stare at Katie too much as she steps closer to you. From the three borrowed bodies, probably she had the best of all. She matured quickly with a visibly curvy figure and just a bit of baby fat around her body.

''So, do you want her?'', Katie motions at Trish, ''or these?'', she grabs your hands and rest them on her bosom, reiterating her question earlier.

''Yeah, fine. Whatever.'', you withdraw your hands and begins to take off Claire's skin. ''I'll be Katie.''

''Sweet,'' she glances at Trish, who just look on as the exchange takes place
