Climb further in

"We'll revisit that," you said, as you brought your hands to the gap in Stephanie's back, causing her to shudder further at your touch. "But let's at least get me fully inside, then maybe we can find a way to make it work once I'm all the way in."

Taking a deep breath, Steph nodded. "F-fair... fair enough. Same as before, just push your arms inside, then I'll start closing up my back. Don't push your head in quite yet, okay?"

"Got it." You took another step away from the glass, causing Stephanie's upper body to droop further, without an easy structure to hold onto while she was open and unworn. Reaching down, you pushed your left arm into her dangling upper body, using your right to help guide your limb inside. Stephanie continued to moan, while you again enjoyed the sensation of her smooth inner skin sliding against your body. It was sort of like inside Stephanie was an inverted version of her, her naked body ready to touch and caress you everywhere. The bulge of your hand slide past her elbow and into her wrist, before your fingers disappeared into hers like a glove. Unlike the hips, the arms felt like they had very little padded material in them, especially the fingers--you held up your left hand, looking at it. Stephanie's small, slender hands now matched yours in size, but with the skin and nails and slight internal tweaks to the shape as it wrapped around yours, these hands still seemed plenty feminine. You rubbed the palm of your left hand with your right, which hadn't yet entered Steph's body. "That feels so weird," you said, "like I'm wearing gloves."

Steph shuddered all around you. "I feel it all," she said, "and it definitely doesn't feel like gloves to me. But it's so odd, feeling so tightly filled up even in my hands like this, and with you making my fingers move against my will. ...Keep going."

As directed, you then moved onto your right hand, using Steph's left hand against her will to further your intrusion. Once you had both hands in place, you tugged Stephanie's body further around you until your shoulders were in place with hers. You didn't have very broad shoulders to begin with, so once Steph began to close up the gap in her back up to her neck, the illusion was fairly convincing--this was a female body from the neck down.

But it wasn't necessarily the same one you'd seen Steph have when she had been hollow! Instead, the padding that had remained inside her slender body now prominently pushed against you, in particular the small breasts Steph appeared to have when she was her own body had grown considerably while on your frame, apparently much of that padding had been stored inside her hollow self. Now instead of what had likely just been an A-cup was a clear C to D, sized and stretched to your frame such that they looked like they were certainly natural on your larger upper body. You glanced at your reflection in the glass, around Steph's head after brushing her hair to the side, your hands immediately grasping at the breasts. You didn't seem to feel anything other than a slight pressure from inside Steph's body against your own chest, but Stephanie whimpered when you grabbed at her form. "D-don't do it so hard..!" she said, biting her bottom lip. "I know I can't stop you if you're going to do that, but at least try to be gentle."

"Sorry, sorry. It was instinct, I didn't know what would happen, like if I would feel them. I guess I don't."

"It's, um, fine," Steph said, sounding almost disappointed when your hands fell to the side, denying her further involuntary groping. "The last part is the head, and it's going to be maybe the weirdest part, okay? You're going to be pushing your face basically into mine, and it's going to take a little time to line things up. You're going to need to go in with your mouth open, and it's going to probably feel like something is pushing into your mouth too, just keep pushing until it feels like you can softly bite down and wiggle your tongue. In that state, I won't be able to talk unless you relax your lips and tongue completely, I'll just be able to make basic noises which is how I'll get your attention, but once you're in I don't know that we'll have much to talk about because at that point, I'm as in the dark as you about whatever's going on around here."

You paused for a moment as Steph's head stretched open wider. You brushed her hair away and looked inside her head in what was a slightly bizarre sight of an inverted face. You weren't sure how she was even able to talk like that, with no obvious signs of lungs, but at this point you knew it was better to not ponder these things. Opening your mouth as Steph had instructed, you pushed further inside her face, closing your eyes as you felt your face push up against the internal skin of her own.

It felt like a strange kiss, almost, the way your lips came to rest against her softness. Once you felt that you'd pushed in far enough--and confirmed as much with your hands on the outside of Steph's face pushing everything together--you bit down lightly, as instructed. Your teeth seemed to slip into cavities that reminded you of the plastic retainers you used to wear, but far more sophisticated. Your tongue, as well, slid into a pocket of something, and you felt a strange shudder and moan as your head seemed to fix itself into place, with Steph closing up her head behind yours.

Opening your eyes, you saw Steph's face--mostly. It was certainly larger to match the larger frame you also had given her, though once again padding around the chin and cheeks and eyes made the shape look natural and still feminine. Brushing some hair away from your face, you ogled your reflection for a decent amount of time, slack-jawed until you felt yourself grunting slightly--that must be Steph's signal. You relaxed your mouth as instructed.

"Get dressed, be ready," was all Stephanie said, seeming to prefer simple phrases at the moment to avoid straining herself while her whole body hugged your own. Nodding, you reached down to your pants and slipped them on, challenged only by the padding in the hips but otherwise the jeans still fit, if a little snug, hugging Steph's ass in a pleasant way. You slipped on the shirt as well, buttoning it up, but not bothering with trying to make the clearly undersized bra work anymore, not even really sure what you would do with it in the first place--after all, you didn't feel it when the nipples rubbed against the shirt fabric, though the light moans coming from Steph confirmed that she definitely still could. You figured she would just have to deal with it for now.

You took a deep breath and looked around, waiting for the chamber to open or something. "What now?" you asked, surprised that when you spoke it came out as Stephanie's own voice instead of her own. As you spoke and paced around the perimeter of your confines, you felt Steph's body shifting lightly against your own, causing her to continue to lightly moan and once again stimulating your cock to harden within a pocket of Steph's body, hidden from view but feeling clearly enjoyable to you. Maybe you and she would have some time to figure out how to have some fun and release that stress before the chamber opened...
