The doorbell rings and you rush to open the door. You're not wearing much; velvet panties and a white oversized shirt covering most of your bare hips. A classic home-alone-with-a-fuck-ghost-outfit. You smirk. You hope convincing Alice won't be too hard...

She just came back from her Dua Lipa concert and asked you if she could have a sleepover at your place, because she was broke and her appartement is currently under maintenance - there were huge marks on the walls from the king-size bed slamming against the wall every night... It's not hard to imagine how that happened...

Either way, she's here, and you'll have to somehow explain the presence of the ghost - no way you're going a night without his addictive pleasure. But you don't know how she will react. You've known her for 11 years now, and so far, she's never been scared to explore the borders of sexual stuff, but this... maybe she freaks out. Maybe she leaves and never speaks to you again. But you are confident, and open the door.

"Heyyy" she says, and hugs you. You hold her for a few seconds and then look at her. She's wearing a tight green jumpsuit, and slight makeup, making her shine. A feeling of jealousy - what if he likes her more - sneaks up in your head, but you press it down and smile at her.

"That's been a while! You look amazing! Quick, come inside." You two walk to the kitchen and you make her a cup of coffee. The little bit of makeup she put on doesn't hide the bags under her eyes. She clearly hasn't slept a whole lot. You two talk and laugh for a solid 30 minutes before you guide her to your room.

"I'm sorry I don't have any other place. I only have a small appartement, and..." She waves your apology away and smiles. "This will be so much fun! A good old girls night, just like when we were kids!" she puts her suitcase down and starts pumping up the air mattress on the floor next to your bed. You help her with the mattress and it's ready in no time. You look at the clock; it's already 6 o'clock! You go downstairs with her and sit down in the kitchen after you order pizza.

"So... I have to tell you something weird" you confess. She frowns and looks serious. "It'll be hard to believe, but please believe me. I can prove it to you, so let me do my story." She nodds and you continue. "So a few days ago, I met this... ghost. I was waiting for a bus late at night and... we met. He made me feel like nobody has ever done before. Then, a few days later, we met again in my appartement. Since then, we have been living together."

Her jaw is basically hanging to the floor and a big frown crosses her forehead. "But... ghosts don't exist, do they" she asks with an sceptic tone. You shrug, and say: "that's what I thought. But I now know they do. Do you want me to call him and tell him to touch you? Not... like he touches me, of course" you blush.

She nodds and looks around paranoid. You yell "David" - that's how you named him. Suddenly, she screams and jumps up. "I- I felt something! I thought you were joking! What the fuck!"

You smile. "Don't be scared, he's a normal guy, only invisible. He won't hurt you." She sits down again and a careful smile appears on her face. "So... this... ghost, or whatever, lives her with you? Is he your... boyfriend, or something?" she asks. She looks mischievous. You knew it! Always interested in her friends love life, silly Alice.

Should you tell her already? You quickly make the decision, and say: "yes. He is my partner." You bring your head closer to hers and whisper: "he fucks like a god! You can't imagine how good it feel! I've never had sex like this before, and I've had quite some boys." Referring to the many one-night stands you had a few years ago when you just got 18.

Alice's jaw drops even deeper. "No way... you had sex with a... ghost?" she whispers in disbelief. "I want to know how it feels" she then says decisively.

Now it's your turn to be astonished. "You... what?! No! He is my boyfriend!" you yell angrily. "You can't just-..." you can't finish your sentence and gasp. He is under the kitchen table. And his tongue is inside you. You try to concentrate and finish your sentence, but all the rational thoughts vanish in a moment - the fog of extreme pleasure covers everything.

Alice frowns confused, but then her face lights up; she knows. "He's... fucking you right now, isn't he?"

You can't help it; his tongue is too wet, too warm, it hits the the exact right spots. You orgasm, squirting your juices on his face and on the kitchen floor. Alice laughs and takes a sip of her coffee.

"Wow, he really got you good" she says. You see something in her eyes that you don't recognise. Lust? Jealousy?

You don't pay too much attention to it as you quickly put your panties back on. You reach under the table and pull them back under your shirt. "As I was saying... you can't have sex with him. He's mine"

      --- Ghost POV ---

Jeez, Harper, come on. Be a bit open-minded. You tried to make it clear that you would love to have sex with Alice - try to make her as depraved as Harper, so that you have enough energy to become even stronger.

But clearly, she didn't get the hint. You love eating her out, but it's never without a reason; obtaining more energy, or in this case, convincing her to have a threesome. Bummer. She's cute and all, but a bit naive.

Alice looks wonderful. Tired, but she is so different from Harper. Harper has medium sized breasts, Alice is rather petite. Her face is much more feminine, with her full lips and big eyes. Luckily, they both regularly run - making their tight asses an absolute pleasure to look at (and not only to look at).

You watch how they open the door when the pizzas arrive. Human food. You smile. So cute. Two cute girls enjoying that simple thing, while you float here, feeding on - for now - Harpers pleasure every evening. They finish their food and go upstairs, to Harpers room. Your heart starts beating a little bit faster. You saw how Alice looked at Harper when she came. She wants you. Absolutely.

         --- Alice POV --- 

Harper goes through the Netfux catalogue and picks out a movie you both haven't seen yet called 'Ghostbusters'. You smile and look at Harper. She smiled back. An appropriate movie, given the situation they were in.

A few hours later, you both go to bed, you on the air mattress next to Harpers bed. You will wait. You are patient - however you are very excited. For how it will feel...

Her breathing is stable and rithmic. This is the moment. You stand up and whisper "Harper". She doesn't wake up. You smile, and then in one quick motion, pull down your pyjamas pants. You shake your ass in Harpers direction. You can only hope and pray he is still awake and gives you what you want.

A minute passes. Two. Five. Ten. Twenty... Then suddenly, you feel something. A big, fat, throbbing cock rubs against your pussy, and Harper moans softly...
