"Oooh, yes, Johnny!" the voice of the temptress carried down the hall.
Johnny? Ryan thought, She's doing it with little Johnny, and she says I have to wait a couple years? He recalled his new size, and looked down at his shrunken body. If sex with her did this to mean, she'll put Johnny in diapers. Well, she's not going to reduce my little brother, if I have anything to say about it.
Big Brother to the rescue. Little Ryan tugged at his sagging pants, and boldly ran forward to the door where the temptress had his little brother Johnny. As he reached the door, the left pant leg unrolled, and he tripped sprawling on to the floor at the foot of the four-poster bed.
"Stop! You're not going to hurt my little bro!" he shouted from his position on the floor.
Two faces and naked torsos peered over the end of the bed at little Ryan. The buxom temptress and a really buff older dude Ryan had never seen before, but he did look very familiar.
"Well, Ryan, you should be happy to see I didn't reduce Johnny."
"John-n-y," Ryan stammered looking at the hunky young man who leaning forward was sporting a dick bigger than Ryan's had ever been. A huge string of cum hung from the mushroom tip arcing downward and over to the temptress' pussy, leaving no doubt what had been happening.
"Ry? Huh, who were you calling little bro, little bro?" Johnny laughed at his reduced brother's new stature.
"Got any more brothers at home, boys?" said the temptress licking her lips.
