“So, little bro, how do you want to spend the week now mom’s gone?” she purred the moment the front door closed. You sensed a trap, your younger sister had only been a child when the Change occurred and you knew from your short failed attempt at finishing school in a woman’s world that young women were particularly dangerous. “… …W-well we could-““*Pffft* Gotcha! Mom put me in charge, silly! Even though she lets you pretend to be independent and that boys aren’t just cute little, boob obsessed idiots these days. Mom’s soooo old fashioned about some stuff. Ms Durham at school taught us that the Change should be embraced and that boys should do as they’re told.”She grinned at you, waiting to see if you would argue with her. You didn’t.“Mom’s not really doing you any favors by keeping up pretenses. I’ve seen you hiding boners while watching her do the cleaning or “accidentally” coming into the bathroom while I’m showering. It’s okay, if mom was more with the times you wouldn’t even be allowed pants in the house and you’d be showering with me every day. Wouldn’t that be nice? her tits were at eye level even as she leaned forwards to give you a full view of her awe-inspiring cleavage.“Uh…” was all you managed. She giggled. “See! You’re just a dumb, horny boy! So this weekend you’re not allowed to wear pants, obviously, boxers either” without thinking about it you started slipping your pants off and she smiled at you as your cock sprang to attention. “and we are going to shower together every day! Ms Durham also says that if I make you cum often enough I’ll get even bigger and prettier! Can you even imagine?” your already throbbing, swollen cock twitched involuntarily. Her smile broadened.“Ooh and you’ll be sleeping in my bed with me of course! I bet by the end of the week I’ll have you begging mom to let you sleep with me every night. That way your balls will be drained whenever you need it and I’ll be one of the hottest in class before you know it. ..I guess she might want to share if I’m bigger than her by the time she gets back but… ah well, at least I’ve got you to myself this week.” she glanced down again at your cock before looking you straight in the eye with a predatory look.“I think it’s showertime now, sweetie. Time to make your big sister’s boobies all soapy and sticky and huge.” -- source link
