Sure!

"Maisie, you will be happy sharing me with your sister."

"Thank you so much", is the only thing Holly says before she leans in and kisses you. You still feel nervous about this, as if you're doing something forbidden, but with the way Maisie looks at the both of you, you decide to just enjoy it and reciprocate. Holly tastes different than her sister, the saltiness of her tears giving a special aroma to your kiss. She doesn't escalate, and for a while you're just sitting there with her in your lap, arms around her in a deep hug.

After a few minutes, Maisie grins at you and nudges one of your arms a little lower, so that your hand comes to rest on Holly's butt cheek. That causes said cheek to wiggle and press into your hand, Holly's tongue starting to explore deeper into your mouth. You feel the heat rising inside you, and apparently so does Maisie, because she's quick to slip between you and the backrest of the couch and grab the bottom of your shirt with both hands, pulling up.

As Holly and you disconnect for a moment to let Maisie undress you, Holly undoes the buttons of her own blouse, revealing a blush that goes all the way down her neck and chest. You help her shuck off the rest of her blouse, then fumble with the latch at the back of her bra while you resume locking lips, her naked stomach pushing into yours. When you finally get the bra open, she wiggles out of it, then sits up in your lap, presenting you with a buffet of her puffed-up nipples. You gently kiss one of them, alternating between licking and sucking and getting rewarded by soft moans from above. Her hands clamp your head against her boob, which you interpret as a signal to get rougher, flicking and gently biting the nipple with your teeth and increasing the volume of her moans.

After a while of this stimulation, Holly pushes herself off of you and lies down on the couch on her back. A frantic removal of her trousers and underpants reveals a familiar sight to you - a tight slit covered by a moist dark fuzz. Lifting your head a little to see further back reveals Maisie, splayed across the corner piece of the couch, with one hand moving beneath her pants. She has her eyes locked on yours (the entire time?) and nods at you in encouragement.

You take this as the final go-ahead to kneel down in front of the couch where Holly is lying and fondle one of her delicate breasts with one hand and explore her pussy with the other. Especially the latter is fresh in your mind from last night, and you recall the pattern that had been Maisie's favourite when she wore this body. Holly's response is a quick crescendo of screams, followed by an unmistakable climax not one minute later.

As you stand up, and Maisie gets up from the couch to finally redeem her share of the sisters' time with you, you hear a key in the lock of the front door. Both you and Holly are frantically trying to get your clothes on before you're spotted by Mary while Maisie hurriedly rearranges the couch cushions, but it's too late, and their mother spots your suspicious activities. She looks at you and raises an eyebrow. "Holly as well, huh?"

"MOM It's not like that, I can explain!" You're not sure which of the two sisters (or both?) just said that.

After a quick and jumbled explanation by all three of you, Mary finally manages to calm you down. "Relax. Holly, I'm not going after you for pursuing Simon as well. If you can make that relationship work, that's completely fine with me. Maisie, if changing your mind in that way was your idea and you gave explicit consent, that's your decision, and I respect that. Holly is a witness to this, so I can be assured that there's no play from Simon's side in this.

"However. The news about Holly's curse is concerning. As far as we are aware, nobody in the entire family has experienced something like this. I don't suspect foul play on the part of your boss - he should be smart enough not to let you get back to your family even if he changed your mind with a command. But if the curse is changing, then... we don't know what could happen to Maisie, or Carly's daughters. If you'll excuse me, I think I'll call Carly and talk to her about this."

With Mary getting up and leaving, presumably to have a private call in her bedroom, the mood between you and the sisters is dampened quite a bit. Especially Holly is clinging to you again. "I don't know what's happening to me. I thought I had my life under control, but now... I don't have a job, apparently my curse is going wrong... even if I'm free, I don't know that yet! Not knowing is what kills me!"

All you can do is hug her back and comfort her. "Calm down Holly. You'll find out everything wrong with your curse soon, I'm sure of it."
