Harper moaned. She... moaned? But... she's laying like an arm length away from her. And the ghost's dick is clearly rubbing your lips - a simple action, but it feels unlike any dick you've ever had. You bite your lip to avoid moaning so loud the entire appartement would wake up. You are already soaking wet.

You look to the side, and you are surprised. Harper is sitting on all fours, being banged from behind by an invisible dick. Her boobs are bouncing back and forth and her hair waves with them. But... how can you both be-...

You can't even finish the thought. A feeling of pure ecstasy floods your head and takes away all logical thoughts as he enters you. Your climax is really close. You can't - and don't want to - contain yourself anymore. "Ohh... mhmm... oh yeah..." you scream as his dick ravages your soaking cunt.

You put your face in your pillow to muffle your screaming as you cum. Your pussy contracts around his dick and your juices flow on the mattress. "You are a slut, Alice Highman" you think in yourself. Letting a ghost take you! But... it feels so fucking good! You're barely done, but you wouldn't mind another round right now. But it's not meant to be, and he pulls out after cumming deep inside that wet hole of yours.

You see Harper also came, and is now laying down, recovering. Damn! Has she had this for a few days already?! This is heaven! You get an idea... to seduce the ghost to give you both more...

     --- Harper POV ---

You barely register Alice also getting fucked. The feelings of jealousy made place for a warm, happy feeling. You lay there, looking at the ceiling, still experiencing the after effects of the amazing orgasms he gives you.

Suddenly, you feel a touch on your arm. Not his touch, but a real, warm skin touching yours. You look to the left and you look surprised at Alice next to you. She has climbed into your bed. She is fully nude, and you admire her body.

Perfect tits. Round, tight ass. Beautiful tan. Her blonde hair and blue eyes. Blushing, you look away - she's your friend, you shouldn't look at her like that.

You breath in sharp as she puts herself next to you in the bed - on all fours, so that your asses are nicely next to each other, facing David. Wait... she wants a real threesome! What is going on! She's your best friend, you shouldn't have sex together with her... but the thought does arouse you.

            --- Ghost POV --- 

Oh my. They have united themselves into the Doggy Union it seems. Both on all fours, their butts next to each other, begging to get penetrated.

Oh well. Might as well give them another round. You also feel the next stage is close. You just need a little bit more energy, and then you could be lifted to a higher level of life again. This might be the one!

You position your hips behind Alice, and hold your dick-hand close to Harper - the other way around this time. You can't see their faces, but you can imagine them as you enter them. Soft gasps and sighs come out of their cute mouths. You are fucking 2 pussies at the same time!

You accelerates, your hips slamming into Alice and your arm into Harper. The juices of the orgy saturate the sheets. The energy flows into you. Yes. More power.

When you cum inside both of their soaked cunts, you feel the change. Your only leftover hand starts tingling and melts. And once again, a fat, throbbing dick comes in its place. Your heart races in excitement; more dicks, more fun, more energy.

However, unlike last time, it doesn't stop there. All three dicks - one on your left arm, one on your right arm and one between your legs - start tingling. Something changes, and as soon as the transformation is complete, you know what changed. A new gland is placed inside all penises, and it produces a strong aphrodisiac.

Aphrodisiac is a mythical hormone - it supposedly turns the receiver into a submissive, sex-craving slut. Their thoughts become exclusively sexual for a certain amount of time, and it also triples the amount of nerve signals the erogenous zones send when stimulated.

You smile. This will very much... come in handy. You grab a piece of paper and a pen from Harpers's nighttable and start writing. "I have gotten stronger again. Thou shall now call another friend, and make them come over. You will all be honored to receive heightened orgasms."

        --- Harper POV ---

You read the note from David. Shit... he wants more. Alice has fallen asleep next to you, probably exhausted from the pleasure centers in her brain being flooded with so much dopamine.

You think for a short while. Who could you call? Maybe Vanessa, but she has a boyfriend... he wouldn't allow her to just come over and have sex - even with something as unbelievable as a ghost.

Oh! Lucy! You haven't seen her in a while! She's one of your best friends from university! You could try her. Luckily, it's only 8pm, so she probably doesn't sleep yet. The phone rings. Once, then twice. Then, someone picks up.

• "Hello?"
• "Hi, it's Harper! It's been a while! I'm having a sleepover with Alice and I was just thinking, maybe you could join us?"
• "Oh my god, Harper, hello! Yeah, honestly, I would love that! A good old sleepover with the three of us, just like in uni! Can I come over this evening still? I have work until 8.30, so I can be there at 9!"
• "That's perfect, I'll prep a bunk bed for you! I'll see you in an hour then, bye, love you!"
• "Okeyy, bye, love you too!"

She hangs up. God, what have you done?! You've lost your job a week ago because you wanted to be with David all day, and Alice will probably be no different. But you both had small, insignificant jobs at a supermarket - you haven't found a job at a real estate company yet, which you studied.

Lucy has a prestigious job at a law company... You can't do this to her. You're about to call her back, but David holds up a note in front of you. "Don't call her back." But the note isn't the most convincing. It's his huge cock penetrating you from behind, sliding deep into your wet cunt, and his lips onto yours, suppressing all your doubts about Lucy.
