"Hmm...Unt...interesting choice, but here we go." Your father gestures to you.

You feel tingly all of the sudden. You grow thicker, muscles enlarge, your body grows much taller. Your push at the seams of your previously loose clothes, and your new package, now very big, is poking through your pants slightly.

"Now, what I've done causes some hormones to go through your system, so for a year or so your new body will be kinda going through a second puberty, except just the emotional parts, but you're an adult now so I'm sure you'll handle that some way. I'll be headed back home now, good luck son. See you later, Madelyn." He rose and left, say bye to Madelyn, your older sister, one more time before leaving. You sit there for a while with your sister as she admires your new body.

"So uh...more hormones huh? Except this time you can't peep on me. That's right, I knew. What did you really think you just happened to ALWAYS catch me undressing or masturbating? You're not that lucky. Truth is, I've always been attracted to you. And with your new body...how about a little test drive?" your sister giggled.

She slowly unbuttoned the small jacket she wore over her robe. Throwing it aside, she reached for her rope tying her long robe together. Pulling it open she reveals two beautiful, round, firm breasts and a trimmed pussy. She walks over to you and, sitting on your lap, she upbuttons your shirt and throws it into the corner with your other clothes, which is quickly followed by your pants.

"We don't have much time, I need to go soon, so just start, I'm already wet."

Standing up and back to the wall, you shove your cock deep into her, producing a gasp from her. You fuck her like this for about five minutes. Then there's a knock on the door. "Hello? Son? There's something I forgot to tell you." Panicked, Madelyn thinks quick. "Get in my robe behind me." You shift around to her butt, and immediately thrust your cock into her asshole. She gasps while tying her robe back, the flowing part easily covering you since you're so close to her. "Come in dad!" She says.

Your dad comes into the room, you are still fucking your sister from behind. "Where's Will?" [BTW-that's your name]

Your sister obviously is having some trouble speaking. "Oh...uh...he n-went into tooown to get some...uh sheets. I said I'd watch the house for an hour or so."

"Oh, well I needed to tell him something. When you see him could you tell him that his erm...well...penis might be getting larger with the change."

"Oh, I know, I mean, I will! I will tell him..."

"Okay, see you later" you dad says as he turns to leave.

"Daddy?" your sister says in a small voice, prompting your father to turn back "Yes sweetie?"

"I want to do it again."

"Sweetie, it was great the first time but-"

"Come on, daddy, it was fun. Pleaseee..."

"Fine, at least this time your mother isn't around to bother us." You hear clothes hitting the floor as your sister draws back her robe to where you are, still covering you, but uncovering her. Your dad walks closer and slowly thrusts his dick into your sister, making her pussy and ass filled. You both fuck her for a while until you climax, followed by your dad, until finally your sister orgasms as well.

"Thanks daddy!"

"Sure, sweetie" he says as her redresses and leaves. You finally step out of your hiding spot. Your sister goes to your washroom to clean up and comes out dress. "Never speak of this. Got it?" You nod as she heads out. This was the first day of your new life.

Next Day
