What a fine young man his younger brother had become. Someone the alpha would be proud to knot with. But this was Ludwig. Gilbert couldn't knot his baby brother. Not in real life, anyway. But in a dream, he could do whatever he wanted.
Which is exactly how he found himself in the current situation.
Gilbert had never been particularly good at differentiating between what was a dream or a fantasy and what was real. He remembered falling asleep. At least, he thought he'd fallen asleep.

He choked back a sob, whimpering when the long, fat, red cock was shoved against his lips, before the younger yielded and opened his mouth, taking it in and feeling his throat being invaded. Why?
