Keeping Eric in mind, you kissed the ring, focusing on his height. You sit there with your eyes closed for a few minutes, then open them. You didn't feel a thing, but your perspective is suddenly very different. Everything looks a little smaller, a little farther away. You go to stand up, and notice the ceiling seems a lot closer. You raise your arm, and without even extending it fully, you're able to touch the ceiling.
You head to the bathroom quickly, stumbling a little on the way. Your increased stride throws you at first, but you quickly get used to it. Several inches of your stomach is exposed as the t-shirt you were wearing has been pulled upwards. Your belly button tingles a little as air hits the exposed area. You step into the bathroom and get your pants off with some effort - they're fitting more like 3/4 length pants, and you're not used to all this extra leg. You finally stand yourself in front of the full-length mirror and examine yourself.
Or, you try to. You have to stoop a little to see yourself fully, you had positioned the mirror for your 5'8" self, not your 6'4" self. You look odd, like a funhouse mirror version of yourself. You notice that your build hasn't changed a bit despite all the extra height, so you probably weigh more now. You think about how you must tower over everybody now, especially your friend Paul who is only 5'6". Even your boyfriend, who had been the same height as you, must now be a lot shorter than you. Thinking about being the big one, him on tip toes when you kiss gets you hard. But then you notice something.
Despite all this height, something feels different, wrong in your now-short boxer briefs. Your eyes drift downward, and the bulge you see in the mirror seems smaller. A sudden sinking feeling in your stomach, you peel them off. You curse Eric silently. Where before, you had a 6 incher, you look down and see something considerably smaller. 4 inches, pointing upwards, still rock hard from your fantasizing. For all that height it looks like Eric was pretty small downstairs. It looks laughably small on your huge frame. You touch it in disbelief, and it twitches with the contact. You want to switch back right away, right now, but then you remember the ring's packaging... only once per day. You're stuck with this thing. Staring at it, you note Eric is uncut, or at least he was a few minutes ago.
You slide the foreskin back, and are floored by how nice it feels. The pleasure is more than you're used to. You sit on the floor in the cramped bathroom, awkwardly bent, the cool tile sending a shiver up your spine. You're disappointed in the reduced size, but you can't argue with this feeling. Sliding your dick back and forth, a few drops of precum drip from your dick. Rivulets splash onto your thighs. You raise your head and look in the mirror, examining yourself, this strange sight. It does nothing to lessen your rising intoxication, pleasure traveling in waves from your reduced member to the distant reaches of your increased legs. Before you know it, you orgasm, cum splattering all over the mirror in front of you, and a final spurt slowly leaking out of your overhanging foreskin. Damn. That felt good.
You clean up, and head to your bedroom. Before going to bed, you call work and tell them you won't be in for a few days. With nothing left to do, you lay down, starting at the ceiling. Your legs are poking a few inches off the end of the bed, and you're very aware of it. With some difficulty, you eventually fall asleep. In the morning, you wake up and look down at yourself, wondering if you're dreaming. With mixed emotions, you remember it's all real. Your head tilts to look at your hand resting on your larger chest, and you see you're still wearing the ring. What now?
