Your sister Emily

Emily, James's bully sister who always never given James his due respect, now looked at her futa brother like she was an intruder in the house, and Emily was clearly of the mind to shriek and call for the police. James merely gave her a look of annoyance, saying, "What? You don't recognize your own brother?"

"And exactly how do you resemble my loser brother?" Said Emily, "And besides, you're female and with that... thing dangling between your legs."

Emily gave James a scrutinizing, disbelieving look at the massive bitch breaker dangling menacingly between those thick futa thighs, her eyes alternating between widening and narrowing.

"My eyes are up here bitch." James smirked, noticing that Emily realized she was staring a bit too hard at her naked brother, "Surely you must recognize the face of your 'loser' brother."

James honestly had to admit that she never thought herself capable of making her sarcasm sound like dripping venom. But at this moment, James found himself being strangely satisfied with the look of utter bewilderment that was currently on his sister's face.

"No, no, that's not possible," Said Emily, "It's you!?"

"Tada," James said, "Say hello to the new James."

"No way, how the hell did you-"

"What is going on here?"

They turned to face their mother Amelia, who stood looking irritated and confused with crossed arms.

"Hey mom," Said James, "I hope you don't mind me being naked."

"...James?" Asked Amelia with surprise, "Is that you?"

"Believe it or not, she is James," Said Emily, "I don't know what happened to him-her, though."

"James, explain," Said Amelia.

And so you told both of them about a specific set of pills you ordered online because you were rather fed up with your small dick size. None of you ever expected such effects on your gender and body, but you do lie that it was the last pills you had on hand; they were secretly stashed away somewhere in the house, and only you knew where to find them.

Having finished your explanation, Amelia pinches the bridge of her nose for a moment, eyes closed in deep thought as you and Emily nervously looked on.

"We're going to have breakfast first," Said Amelia, "And don't think of making a big fuss of it, both of you. Also, James put on some clothes."

Neither of you could entertain such thoughts, with how serious your mother scolded the both of you.
