A new family

The room fell almost silent, the only sounds barely audible is the deep breathing of the three of you, the intense sex has drained all the energy from your body, you and Marcus are sit on the floor thinking who will be the next one.

But soon the peace got interrupted, the sound of the door opening usually won't make you feel anything but, in this particular case, the fear that someone can find out what you are doing take over you.

A female figure makes her entrance inside the room: her blonde bob haircut, her cute face, her toned body with decent breast and firm ass, her long legs, is dressed with tight red jeans and a white blouse...

She's Lucy, your 28 years old stepsister.

She comes inside the house, than slowly turns into your direction and remain completely stunned by the scene in front of her eyes, her stepbrother and his friend completely naked on the floor and a creature she never seen before on the couch, although that anthro cow remind her someone...

After some seconds of staring contest, she manage to spit out some words," What... Who... You...", clearly Lucy doesn't know what's the more appropriate question in this situation and that's fine because you neither know how to explain all of this.

But your thoughts are interrupted by some arcane words pronounced by Marcus, at first you've the intention to stop him, but then? How are you going to explain this? So you let him do the spell.

Lucy can't quite understand what he's saying and she was about to ask when she feels her mind becoming lighter, difficult thoughts are replace by simpler one.

Soon her worries fade away to leave the space to an animalistic need, something more primal, Lucy try to fight back this sensation but the power of the transformation is too strong for her will, her arousal grows every second.

"Sorry bro, I have to do it! We can't risk someone find out what we found..." Say Marcus, he keeps to look at Lucy and he seems to enjoy the wet spot on her red jeans getting wider.

"I know bro don't worry, Lucy was a real bitch with me so she deserves it too..." You pause a moment to enjoy the view too, "... Anyway, what spell do you use?"

Marcus give a look at the book the answer," Is the horny rabbit spell, I've had a short amount of time so I opted to change just her mind and fast of course", you're surprised by his acting under pressure, that was surely the best choice to do.

You give a fast look at your step mother, she's still trying to rest and a question naturally comes to your mind," Bro, have you read something about what happens after we turn back to the human form? I mean, is aware or unaware of what's happened?"

"Emm... I don't know, maybe there's written something about it on the book?" Suggest Marcus, so you both decide to calmly read the book on the table trying to find something about this.

After almost two hours you haven't find anything useful, the book doesn't saying anything on what happens when a transformation is reversed, "What now? I don't know how many times we have..." Say Marcus, you and him turn your head to give a look at the two woman, Lucy is sit on her mom's face and she's eating her pussy daughter, clearly Lucy is dreaming to have something else inside her cunt.

"Well I think we have plenty of time, for now let's go to bed, my stepmother drain out all my sperm..." You feel really tired, is late night and a new day can bring new ideas,"... Bro you can stay here for the night, no one will object," Marcus nod affirmatively, so you both go to rest while Lucy and your stepmother are still enjoying their transformation.
