Slight amusement and jealousy

You brush off a rock and sit down during the witch's display, a slight twitch of amusement crossing your face, though you can't help but feel a pang of jealousy as her youthful body strides out. Avoiding old age had always been a goal of yours, and after seeing her do it so easily, you can't help but feel that the decision to keep the book was the correct one.

"You look absolutely stunning - not that you weren't before." You shoot her a quick wink, leaning back onto your arms. "What else you got planned? 8 minutes left by my approximation."

"Oh, dear, I know exactly what I'm doing." The witch finishes with a wink as pages begin to turn again, settling down on another section. "Ah, yes, this is magic I've done several times before on my own, but the book helps me to focus and customize things exactly as I'd like. After all, it's hardly meant to be used on people like us." Her eyes glaze over slightly as she recites her next incantation, sinep eht egralne, ytiliriv esasrcni

There are significantly less sparks this time around, but they concentrate directly in the front of the witch's groin, just above her hairless, pink pussy. Her laughter, surprisingly, turns to moans, as the magic seems to spread out and down slightly, and when it fades several seconds later, she's grown a penis, to put it lightly. Large enough to dwarf most men, it hangs almost to her knees, thick and uncut, the tip completely covered by its foreskin and already leaking a few drops of precum.

"Not too bad, if I do say so myself." You can see the veins pulsing in her new member, its hefty weight twitching with each breath, and she uses one of her hands to explore its shaft, lifting it slightly into the air. "I had to get rid of my last one when I got too old, past a point it just isn't the same." She turns back and forth quickly, swinging the dick from side to side, before looking you straight in the eyes and giving another offer. "If you'd like one of your own, I could make that happen."
