Wear Sasha instead

You unzip the Jessica suit. Slowly, but surely, your malicious grin goes from Jessica's face to your own as the former is peeled off the latter. Jessica's skin falls onto the floor and you turn to the bed.

"Well, Sasha, I'm gonna be you now", you say as you untie her skin from the bed, clean it up a little and start stuffing your legs inside. You can almost already feel your dick getting hard again as you start feeling your body morph into hers.

Having put everything on except the face, you look into the mirror and mischievously say "I'm gonna have some more fun with you, Sasha" as you put on the mask and finish zipping the suit. You take a few seconds to appreciate your new body as your new curves delight you.

"Well, well, well! What a naughty little slut am I?" you then make your dick pop out. "Oops! What is that? I'd better hide that!" you add as you put your hand on your mouth, before absorbing your dick back in with a grin.

Your attention then turns to the box. You find another pen, a brown one. It has a small note on it that says that it's supposed to inject the wearer with the memories of the person they are wearing and the ability to act completely like them as long as they are wearing them. You zap yourself with it and suddenly remember all of Sasha's life.

"Well, seems I'm even more of a slut than I thought!" you say as you remember every single sexual interaction Sasha has ever had and...you find that there are a lot of them, some very questionable. However, now, no one will ever suspect you. From now on, you will act so indistinguishably from Sasha that you can spend your entire life as her if you want. However, if you wanna do that, you should probably avoid turning Jess back right here, right now, otherwise, it will be painfully obvious you are Sasha.

You then wonder what would happen if you zapped a deflated skin with the brown pen. Would it have any effect?
