Of course you notice!

You wake slowly, the morning light filtering through the blinds in soft gray stripes across your bedroom. Your body feels heavy, languid, like you’ve slept deeper than usual—but there’s something off, a strange, pleasant ache deep in your hips and a warm, sticky fullness between your thighs that makes you shift uncomfortably under the sheets.

The first thing you notice is the wetness. A lot of it. Your panties are soaked through, clinging to your skin in a way that’s far too thick and slippery to be just sweat or normal arousal. You freeze, a cold prickle running down your spine as fragments of hazy, erotic dreams flicker through your mind—pressure, heat, being filled so completely it bordered on overwhelming. You squeeze your thighs together experimentally and feel a slow, viscous ooze seep out, coating your folds and trickling toward your ass.

Heart pounding now, you sit up carefully, the oversized t-shirt falling around your hips. You reach down with trembling fingers, slipping them beneath the waistband of your panties, pulling them off. The fabric is absolutely drenched, and when you pull your hand away, your fingertips are coated in a thick, pearly-white substance—creamy, slightly stringy, unmistakably cum. A lot of it. Far more than your body could ever produce on its own.

Your breath catches in your throat. You spread your thighs wider, peering down in the dim light. Your pussy looks swollen, lips puffy and flushed deep pink, glistening with a glossy sheen that isn’t just your own wetness. As you part your folds gently, more of the load leaks out—a slow, steady dribble of your brother’s seed, warm and heavy, escaping your stretched entrance and sliding down to pool on the sheet beneath you. The scent hits you then: musky, salty, unmistakably male, mingled with your own feminine aroma.

Memories crash in all at once. Your brother staying over. Asking him to watch over you. Falling asleep trusting him to protect you from exactly this kind of risk.

A wave of heat floods your cheeks, followed immediately by a colder rush of betrayal and panic. He did this. While you were asleep. He crept in, used your **** body, and deliberately finished inside you—deep enough that you can still feel the lingering ache where he pressed against your cervix.

Your hand drifts instinctively to your lower belly, pressing lightly over your womb. It feels tender, full, as if something warm and heavy has settled there. You know the rules of this curse intimately: if even a single drop reached your womb unprotected, the 48 hours are void. The transformation becomes permanent.

And from the sheer volume still leaking out of you—thick ropes of it that keep coming every time you clench—there’s no question it reached exactly where it needed to.

You sit there in stunned silence, thighs sticky, panties ruined, your brother’s cum still slowly seeping from your freshly bred body. Somewhere down the hall, you hear the faint creak of the couch as he shifts in his pretend-sleep, waiting to see if you’ll notice.

The realization settles over you like a heavy blanket: you’re not changing back. You’re staying a girl. And deep inside, your brother's incestuous life has already begun to grow!
