Ashley slowly reaches up, feeling around in the space where her head should be for a moment, as though confirming that it really is gone, before allowing her fingers to drop down to her empty shoulders, tracing the cut surface, her body giving a little shudder as she does so, though whether from cold, fear, or excitement, you really can't tell. After allowing her to continue her explorations for a moment longer, with Ash getting more and more into it, rubbing away hard and fast at the blank space between her shoulders, you decide it's time you got her attention, reaching down to her belly and tracing "Head?", causing your girlfriend to wiggle and squirm, attempting to slap your hand away. "Hmm, she really is ticklish." you mutter to yourself. Still though, you need to make sure that Ash is okay with this, so you try again, trying not to tickle her too much this time. Fortunately, this time she seems to understand, for almost as soon as you've finished tracing the words, the give you an empathetic no in the form of a double thumbs down, letting you know in no uncertain terms that she likes this, and wants to remain headless for a while longer, something you're perfectly okay with. Plus, if you're lucky she'll.... Yep, looks like she's ready.
You watch in fascination as your headless girlfriend begins to strip, which doesn't take long as she wasn't wearing much to begin with, before laying down and making a come hither gesture towards you, leaving you with absolutely no question as to what she wants.
Quickly shucking your own clothes, you climb on top of her, Ashley spreading her legs to accommodate you, then begin groping and squeezing her breasts and sucking on her nipples. You do this for a little while, before moving on, your hands slowly tracing their way down her beautiful body as you begin to kiss her neck stump, something that Ash seems to enjoy almost as much as having you suck on her breasts. Deciding you've played around enough, you prepare your self for the main event, grabbing hold of your dick, already rock hard, and shoving your way into your girlfriends dripping hole, pounding away at her tight snatch until she orgasms, her pussy squeezing around you like a fleshy vise, clenching and clenching rapidly, milking your cock, and forcing you to cum, shooting your hot load deep inside her. It's a good thing your girlfriend's on the pill, otherwise the two of you could be in trouble after that kind of load!
Having satisfied yourself and your partner sexually for the moment, you turn your attention to other matters, namely restoring Ashley's head so you can find out how she enjoyed her first taste of headless sex. Picking up the katana, you press and hold the red button for a moment, causing reality to reset itself, just as the paper said it would, something that you honestly weren't sure of until now, and causing you to breath a sigh of relief.
Ash however looks a little miffed, something she soon confirms as she complains "Awe Jason, did you have to? I was really enjoying being headless!" she says with a pout.
She looks so cute when she's angry that you almost laugh, though you can't quite hide your grin as you explain "Sorry babe, I just had to know how you were doing. I take it from your reaction that you enjoyed yourself?" you teased.
Her face adopting a blissful expression, Ashley replies "Oh my God yes! I couldn't see or hear anything, but my sense of touch was just out of this world! You should really try it sometime!"
"Hmm, maybe later." you reply noncommittally, unsure if you're really willing to give up your head or not, even if it is only temporary. "Anyway, what would you like to do now?" you inquire.
Her face taking on a thoughtful expression, Ashley replies "Hmm, well, I'd really like to be headless again, but we already did that, so that can wait. I guess we could___________________?"
