Sitting on the bed, I try to both listen to the heated discussion going on in the other room and distract myself from the past few minutes' events. My girlfriend’s half sister got separated at a party; apparently is one of the super rare types of girl who becomes 2 partial people when split; has a crush on me; and her body tried to make a move on me in front of Sara. That’s a lot to take in over the span of like 15 minutes…

I can only hear the muffled sounds of them talking through the door, and at first it doesn’t sound good. They are aggressively (and loudly) talking quickly back and forth, probably arguing. However, within a few minutes the sounds taper off to a normal volume, and I think I hear the occasional laugh? Hopefully that’s a good sign.

I hear a pair of footsteps approach, and brace myself for what’s next. They both step through the door, Sara in front and Sabrina attempting in vain to hide behind her, clearly still a bit shook up and wary of my reaction to whatever happens next.

“Ok, so we had a chat. At first I was extremely ticked off at my sister for trying to make a pass at you right in front of me, but I think I was probably reacting a bit too harshly. She genuinely wasn’t fully there in her body, and she was just as shocked as I was. I didn’t know, or was ignoring, the fact that she had a huge crush on you this whole time, and I probably should have figured it out a long time ago.”

“That’s fair, I was wondering why she was so shy myself - I thought I might have offended Sabrina earlier and forgot about it or something, or maybe was just intimidating for some reason? I dunno.” I reply.

Sabrina, still hiding behind her sister, replies “I’m glad we’re all on the same page now, but I'm sorry it had to happen like this. I have a lot to learn about myself now, and it sounds like I’m going to have to be careful with getting disconnected, at least until head me and body me get on the same page. She takes a step out from behind her sister, and I ask “So, what’s our next step? It sounds like you two reached some kind of arrangement out there, so what’s up?”

Sara bites her lip and looks down for a second. “I have a bit of a confession to make.. Once I got over the shock of seeing my sister’s body being extra handsy with you I realized that I wasn’t just surprised and upset at her. I was also getting extremely turned on watching someone else make a move on you. I didn’t think I was the sharing type, but I guess you learn something new every day...”

“Oh? Oh damn. That’s not exactly what I was expecting. Okay, umm…  so you’re both cool with that?” I ask, in shock.

“I guess? I mean, it wasn’t really me there when my body was doing all that. It was sorta but like another version of me. I remember it now after I got back together, but it’s like that part of me was finally free and could act without all the inhibitions I have. Of course, it’s awesome to find out here with you guys instead of somewhere else for my first time. Also it’s good that Sara’s not killing me right now so I guess I got lucky that she’s more or less ok with it.”

Sarah speaks up - “Yeah, that’s another thing - it’s not totally her, so it’s sorta like another person made a quick appearance, a lot like when I was disconnected and you were having fun with Miss Head. I wasn’t there really, basically nobody was, but it was still sorta me, in a way. In sis’s case, it sounds like she remembers what happens afterward once she syncs back up, which is really cool.”

“Miss head? What’s that?” Realization crosses Sabrina's face. “Ooooh, your head when you’re doing the whole being a body thing… Kinky.”

“Indeed. Anyways, I think we have a solution to our problem. Try to follow along with my logic, hopefully this mostly makes sense”, Sara says.

“First: Sabrina definitely has the hots for you, and her body clearly is much more enthusiastic when separated.

Second: With Sab’s crazy separation, she can leave her head and most of her mind behind, and her body can still act without her. That means that she can basically take a little head vacation and remember what her body did afterward.

Third: If she can let her body take over for a bit, I think she can pop this whole shyness bubble; along with figuring out this whole separation thing without ending up in some government lab or something.

Fourth: Having her body make a move on you is really fucking hot.

So, as long as you both are still down, and if I can watch from over here and hang out with Sab’s head, I’m more than cool with you two doing whatever this one time. No commitments, and hopefully it won’t get more weird than it already is, but weird started like a half hour ago. We both already share basically everything - why not a boyfriend once?”

Sabrina looks into my eyes briefly, and nods at me. I nod back.

Sara says, “Ok, so let’s lay some ground rules. If anyone wants to back out, like if it gets weird for you, well weirder than it already is, say so at any time. Sabrina, when you’re in head mode, same rules as before - stick out your tongue and we stop everything. I’m not sure about your body but it should remember this; and I think you’ll figure something out. Also, you gotta wear protection. I know sis is on birth control, but it’s still a good idea.“

Sabrina takes a seat on the bed next to me, and although she’s clearly still nervous, she looks determined to see through whatever happens next. I say quietly to her “Are you really sure about this? I don’t want it to be a problem later.”

“Worst case we’ll still have a good time. I’ve been looking for a boyfriend since moving out, but I’m also down for some commitment-free fun - especially if I already know he’s a good guy.”

Ok, here we go.” Sabrina says, then lifts her head off and hands it to Sara. While she’s still in control of her body, I take Sabrina’s hand and guide her to a seated position on the bed.

Sara says “One sec”, and opens up the nearby dresser drawer, removing a signal blocking drawstring pouch and setting it on top of her desk. She says “Hold on sis, I’ll get you separated”, then sets her head into the pouch and pulls the drawstring snugly around her neck. Her body slumps a bit as her consciousness reshuffles, then perks back up as her body figures itself out.

I feel her hand lightly squeeze mine, as her head watches from the desk next to where her sister is seated. She silently looks a little shocked and glances over at Sara as she watches her body start to move on it’s own. Holding her hand, I attempt to fingerspell in the most basic way. I spell to her “Hey r u there?”

Her body pauses, and signs back to me “Yes, I’m good. I know a little sign language from school, so we can chat a bit. It’s pretty cool having no head - she’s kinda dumb sometimes. So, wanna do it? I get to do whatever I want and they get to watch. Head me probably will never let me out after this, haha.”

Sara and Sabrina’s head see the conversation, and Sara leans over and whispers something into her half-sister’s ear. Whatever she says, it elicits an even deeper blush from Sabrina and she looks over to me and bites her lip slightly.

I help her body remove her shirt, exposing her slim figure and her black silky bra. I quickly remove my shirt as well while she pops the clasps on her bra and tosses it aimlessly to the side of the bed.

She falls back, popping her hips up and removing her skirt and panties in one quick motion; the discarded fabric sailing off toward her half sister and her disconnected head.

Her body, now fully on display before me, is a stark contrast to her sister though stunningly beautiful in her own right. Her upper body is surprisingly petite, and the years of dance classes and figure training have left her with an unbelievably slim waist and stomach. Contrasting her upper body, her hips spring out into a fit but drastic pear shape. Lying back, one of her hands moves up to her chest, the other one beckoning me closer.

I quickly remove the rest of my clothing and glance over to head Sabrina, her neck resting on the desk with Sara seated nearby. Clearly she approves of me, and her expression shows that she’s as worked up as her other half on the bed.

As I climb onto the bed, her body signs to me “Let’s go dude, make my head jealous.”

Sara says to her sister’s head “Oh yeah, if I hadn’t told you yet - he’s pretty damn big, your body is in for a hell of a surprise…”

 I move in and slide two fingers into her, and although she startles a bit, being unable to see my approach, she is clearly already ready to go. After working on her with my fingers a bit, I waste no time getting to the main event. I grab hold of her hips, and forcefully but gently turn her over. She gets the message, rising up onto her hands and knees. I lightly squeeze her ass and quickly reach over to the bedside drawer and grab a condom. I roll it on and grab hold of her hips, and she dips her upper body down farther to give her fantastic ass a better angle. I guide my cock into her slit, pausing at the entrance for a second to give her body a warning and working in with a few starting strokes. She startles at first and hesitates, but once she seems to adjust to the size, she responds with enthusiasm. She slides her hips backwards into me and quickly brings my cock deeper inside. As she rocks her ass backwards to start taking full strokes I reach my hands around her miniscule waist for leverage, and am surprised when my fingertips can almost touch.

A few moments later, I see in the corner of my eye Sara grab hold of her half-sister’s head and walk over to us. Holding her head like a camera, she walks around to find the optimal angle for Sabrina’s head to get a good view of her body acting on its own. Although silent, her expression gives away her extreme turned-on-ness with no way currently of doing anything about it.

I ask Sara “Hey, want me to give her a really good view?” Sara hands the roving head to me and I hold her up near my own head, giving her the same view I have of the action.

Sara hops onto the bed, lies next to us, and slides her hand down her pants to enjoy herself while enjoying the view.

I say to Head Sabrina “It looks like you're having some trouble - I know a thing that I think might take the edge off until you get hooked back up. Wanna try something new?”

Her neck tilts in an attempt at a nod yes, and I turn her head over to face up and set it on her body’s back. While still hammering away at her body, I use my free hand to lightly massage the underside of her neck through the signal blocking bag, gently rubbing the spot where her spine stops. Her eyes roll back and her mouth opens in a silent gasp, as basically every nerve in her spine sends her some good feelings directly to her brain. “I hear this feels like a massage everywhere at once, and it looks like you agree…”

Although her body can’t speak to me and her hands are busy holding her up preventing any sign language, she clearly signals that she’s about to cum, tightening up and increasing her pace. I've been holding back for a while, so I quickly stop attending to her head, grab hold of her hip and pull her toward me hard. She comes a second before me, and we both take a final few strokes as I pump deep into her.

I take hold of the condom and withdraw myself, and the now overwhelmed body in front of me slumps forward. I quickly catch her head before it can roll off her back, and set it next to her body. Once Sara composes herself for a moment she reaches over and pulls the signal blocker off of her sister’s head. Sabrina’s body gasps and twitches slightly while her eyes roll and her mouth opens and closes a couple times, reconnecting after all that being really disorienting.

After a few seconds, Sabrina grabs her head and reconnects, saying “Holy shit.” Sara asks “Glad you got split? Seems like you had a good time..”

“Fuck yes. I think things are different now - being two people for that long is really weird. I need some time to figure out my memories, remembering two different timelines at the same time is pretty confusing. I probably have been ignoring myself for too long, and body me had to point that out. I think I need to hang out with body Sabrina when I get back home and get on the same page.”

“Yeah that was awesome, but are we all still good?” I ask, a bit worried about where we go from here.

“Yeah, that was pretty fucking cool. I expect you to do the same thing to me later though, so you better have some stamina left over.” Sara replies
