My Mom's Out Of This World!

Arietta Adams, a teen, returns home and is upset. Maggie Green, her stepmom, tries to figure out what's wrong. Arietta starts telling a story involving a school bathroom, saying that her human disguise was so itchy that she just HAD to temporarily remove it. Wait... Arietta isn't human?! Yes, it's revealed that Arietta is an alien, and that she may have accidentally revealed her true form to a human in the bathroom! Luckily, Arietta was able to convince the human that she was just seeing things, due to stress. But it was a close call.

It's further revealed that Maggie is ALSO an alien, and that they are lovers on their home planet. They've been sent to study humans, and are stepmom and stepdaughter as part of their cover story. Great cover story, huh? Arietta and Maggie get frisky, admitting that even though their disguises are itchy, having human sex is fun. They then playfully insist that it's crucial to their mission to discover the appeal of stepmom and stepdaughter sex.

They try out sex in their human bodies, removing their clothes and exploring each other with their hands and tongues. What fun! In fact, they decide that playing into this relationship seems to be a great way to keep humans distracted from discovering that they're aliens. Sounds like a brilliant plan!
