Yes, of course she has another idea

Sarah thought about it for a moment longer, observing the deflated skin of Katherine that was laying on the bed next to us. She still had that spark of curious excitement in her eyes.

"So..." She started. "The way your abilities work is that you absorb the soul of the person you skin, right?"

I nodded.

"And then to 'restore' a skin, you just inject the soul back inside it?"

"Yeah. Why are you asking that?"

"Do you think it's possible to inject a soul in a different skin?" She asked, looking back at me.

"Huh?" I didn't even think of this possibility, but it was intriguing. "Hmm, I have no idea. Maybe?"

"Why not try it now?"

"That... would require me to skin another person, though... And I don't want more people to know about my situation."

She playfully punched my arm. "You don't have to worry about that. There's one person you can currently skin to try it out." Seeing my confusion, she pointed at her face. "I am here, remember?"

I stared at her. "You... You want me to skin... you?"

My skinwalker side was awakening as I was processing what she said. The urge to wear her diminished greatly since I wore Katherine, but a small part of me still wanted to try to become Sarah...

"I... I'm not sure if it's a good idea, Sarah... Especially with how I felt when I skinned you by accident last night..." I replied more timidly.

She held my hand and smiled. "Ed, I believe in you. I said that because I know I can trust you."

I gulped, still a bit unsure, but relented. "Okay, we'll try... You want me to transfer your soul into Katherine's skin, then?"

"If it's possible, yes." She replied.

I slowly freed the spines, Sarah observing them curiously. "Alright. Do you... have a preference about where I should stab you?"

"Hmm, maybe the arm? I think it'd be less painful."

I nodded and held her arm before plunging my spines into her flesh. She winced and grit her teeth, but didn't feel the pain for long as I quickly started to absorb her soul. Witnessing her deflate in front of me brought me some conflicting feelings. A part of me was jubilating, pushing me to slither inside her skin immediately, while another part disliked seeing her like this, reduced to a hollow skin.

I didn't have much time to dwell on that, though, as I was assaulted by a splitting headache as soon as I was done absorbing her soul. Sarah and Katherine's memories were tangled inside my head, it was overwhelming for a moment... until I felt the side of me that was skinwalker expand to safely store both souls and sets of memories within me. It was a very surreal sensation, but I let out a sigh of relief as the headache faded.

I observed Sarah's skin for a moment, the urge to wear her returning in full ****. I wondered if I should try. Knowing her, it'd probably be an interesting experience to see someone else wearing her skin, and would most likely be less uncanny than seeing her skin deflated like this. Of course, this was just a somewhat flimsy justification my mind had found to make me feel better about these desires I had.

And it'd probably be funny to see how she'd react, too...

She had her fun with my abilities earlier, but it was my turn now. I undressed and grabbed Sarah's skin delicately, my desires growing even stronger as soon as I held it in my hands, and my arousal too.

I wore a woman once already... I can wear one again... even if this one is my girlfriend...

I cut an opening in her back and slid my legs inside hers. The same sensation I felt as I wore Katherine flared up, her legs tightening around mine until I felt the carpet through Sarah's own feet. I took a deep breath and pulled up, bracing myself. Despite knowing what was about to happen, I still moaned and gasped, and fell on the bed, the sensation of Sarah's genitals replacing mine being even more intense than with Katherine's...

"God... Will it always be that intense...?" I wondered as I felt my new vagina getting wet.

After regaining my composure, I took another deep breath and pulled her face over mine. Sarah's skin tightened all around me, and her memories felt even more present in my head as I became her completely.

I opened my eyes and smiled, feeling so incredibly good. Being Katherine was already a very enjoyable experience, I had to admit, but being Sarah was on a whole other level. Everything felt perfect, euphoria overtaking me as I approached the mirror to observe my reflection, admiring my body in detail.

"You're so beautiful, Sarah..." I spoke, enjoying my soft voice, very different from Katherine's lower tone.

The small jealous part of me wanted to dig into her memories and see what happened with Michael earlier, but I did my best to resist. I definitely didn't want to betray Sarah's trust in me.

I took her clothes and got dressed, ignoring the strange mix of weirdness and arousal I felt as I wore Sarah's underwear. After putting on her jeans and blouse, I went to Katherine's skin, freeing the spines from my now slender hands. It was kinda freaky to see them pop out of such delicate hands, but I also felt Sarah's fascination for them. I stabbed the skin and focused on sending Sarah's soul inside it. It was surprisingly easy, and I quickly felt her soul leaving me as I saw Katherine's skin being restored.

I smiled, satisfied that it worked, and sat on a chair nearby, crossing my legs and observing Sarah as I was waiting for her to regain consciousness. I was excited to see her reaction. Maybe it was due to the euphoria I've been feeling, but I wasn't really afraid anymore. I was very confident, in fact.
