The two Slitheen waited for their brother to arrive. Both of them got used to the strange rituals that humans obey. Brushing their skin's teeth on a night, cooking human food (even though they hated it) and doing the washing up. The other students who occupied the house, Faye and Andrea, didn't even notice much of a difference. Daniela and Lola would even continue watching Netflix show's that their victims had started. It was quite and education for them. To relieve themselves of the gas build up and to breathe the fresh(ish) air they would occasionally unzip when everyone was asleep. They would even take it in turns trying on each other's skin.

One evening the two were watching a programme when Lola's phone started ringing. The two slitheen looked shocked, it was her boyfriend Ethan.

Megra Slitheen (Lola): "I have a boyfriend?"

Magra Slitheen (Daniela): "She HAD a boyfriend."

Megra Slitheen slitheen answered.

Megra Slitheen (Lola): "Hello?"

Ethan: "Where have you been, you've not answered my texts or calls are you okay?

Megra Slitheen (Lola): "Yeah I'm fine, I just haven't been feeling myself recently, I don't know what's got in me.

Ethan: "Well can I come over to see you at some point, it feels like you've been avoiding me and everyone recently."

Megra Slitheen (Lola): "Yes of course, I would like nothing more, maybe Friday?"

Lola hung up the phone and smiled at Daniela, the smile then turned into laughter, evil laughter.

Megra Slitheen (Lola): "I think we can have some fun with this one sister."

Five days had passed. Mugra Slitheen piloted his ship into orbit and activated his communicator.

Mugra Fel Fotch Slitheen: "Ladies I am in orbit above the planet, have you got me a disguise?"

Magra Slitheen (Daniela): "Evening brother, yes we've got one on the way, we'll keep him warm for you."

Megra Slitheen was busy in the bedroom applying makeup to Lola's face.

Megra Slitheen (Lola): "Even with makeup on humans are still ugly."

Magra Slitheen (Daniela): "Humans would class you as pretty."

Just then there was a knock at the door.

Lola had one final check of herself in the mirror, straightening up her skin. As she left her room, she let out several farts, trying to get them all out before she answered the door. The smell of bad breath filled her room. She walked down stairs and answered the door.

Lola: "Oh hi, come in"

Ethan entered he had some flowers in his hand, he entered, Lola closed the door behind him but didn't lock it.

Lola: "I've been super busy lately and then I came down with a stomach bug but I'm better now."

Ethan: "That's good, I have been really worried for you, you've basically been off the grid for two weeks.

"You haven't even been uploading to Instagram, which is not like you."

Lola looked at him confused, she nodded not having a clue what Instagram was. She felt her stomach rumble, she was hungry for humans.

Ethan: "So do you want to go out and get food or have a few drinks."

Lola didn't want to drag things out more than they needed to be.

Lola: "No, how about we skip the chit-chat and get straight to the bedroom?

"We're the only ones in, Daniela is out picking up her brother, and the others are out so its just us.

Ethan immediately got excited and followed her up to the bedroom, upon entering her could smell bad breath. He was almost knocked off his feet by it.

Ethan: "Wow are you sure you're over that stomach bug of yours."

Before he could ask anymore questions Lola began to strip. She took her top off and pulled down her trousers. Ethan noticed that her boobs and bum looked bigger, but he assumed that it was just new underwear. She pulled down her pants and bending down as she did so, letting out a massive fart. Ethan also began to strip.

Pharrzzzeee! Blpt

Lola: "Oh guess I'm not over the stomach bug do excuse me."

Ethan: "You look amazing."

Lola: "Do you think? I'm not so sure."

Ethan was not put off by this and the two of the got intimate on the bed. Just then there was a knock on the door.

Lola: "Come in darling"

It was Daniela, she entered the room, Ethan was stunned and stood up. He didn't know what to do, someone had just walked in on them having sex.

Lola: "Oh no, I thought because I've been a terrible girlfriend, I thought I'd make it up to you with a threesome?"

At that moment Daniela took her top off, undid her bra, pulled down her trousers, and then finally her pants. The two of them stood naked in front of Ethan, who couldn't believe what was happening.

Daniela: "Shall we."

Ethan: "Of course."

They got back to being intimate, the two slitheen could feel a build-up of gas as they chafed. Ethan was kissing Lola; little did he know he was kissing dead lips. As the moment reached its climax Ethan saw a zip in Daniela's forehead, but thought nothing of it, he was distracted by the moment. Suddenly he unleashed his load over Lola's face. This time he knew he wasn't making it up. He saw Daniela's forehead, again with a zip in it. He turned to Lola who had got up to wipe her face, Ethan was about to speak up and tell Lola but then she turned round, she too had zip in her forehead.

Lola: "What's wrong Ethan?

He was speechless he didn't know what was going on.

Lola: "I see you've noticed my latest feature; do you like it?"

There was an awkward silence, just then Daniela farted, it was a loud one her large naked arse erupting.

Pharrzzzeee! Blpt

Daniela: "You were right sister; this was rather fun but it hasn't helped with the gas exchange.

Ethan looked even more confused? How could they be sisters they look nothing like, they have different eye and hair colour, they not even from the same country.

Lola: "I can see you are quite confused Ethan, don't worry we can, oh hold on"

pppppppppfffffffaaaarrrrrtttttt

Lola: "Oh there I go, shaking my arse."

Daniela laughed a farted again, before she grabbed Ethan and held him in place so that he couldn't escape.

Lola: "Where was I? You see Ethan, I have this zip in my forehead for the same reason you have zips on your human clothes.

"I have been wearing Lola, and my sister Magra has been wearing Daniela. These are our disguises and what fun they have been."

Just then there was a knock on the door.

Lola: "Come in"

The door opened slowly, Ethan could see a green claw before a giant alien creature, all green and slimy came through the door. It has about 8 feet tall and had a compressor round its neck.

Lola: "Ah brother, I hope you had a good trip, sorry for keeping you waiting so long."

"Ethan this is my brother Mugra Fel Fotch Slitheen, he is going to take care of you, in fact he is going to be you.

Ethan struggled as he tried to shake off Daniela's grip but it was too strong, she held firm holding him in place.

Mugra Slitheen moved closer and closer, he raise his claw up in the air.

Lola: "Wait! I feel like since Lola was his girlfriend it's only right to show what happened to her.

"And as much I love being naked as a human these flesh suits are do chafe.

"So if you would allow me."

She pushed her hair back, she began to pull the zip in her forehead bathing the room in blue light. Mugra Slitheen and Magra Slitheen (Daniela) laughed as their sister pulled Lola down and she fell to the floor.

Megra Slitheen (Lola): "Now I am truly naked, but I don't think you will find me attractive anymore."

Megra swung her claw at Ethan and that was that.
