You wake up feeling great. A rarity, so you think you must've had sex last night.
A bit of backstory on the characters:
Oscar: YOU! The most ordinary person on this earth, rare, I know. 19 years old. Usually the pred, unwilling prey.
Stacy: Your eldest sister, 21 years old, light skin and extremely big. Giantess levels big. She usually ignores you, but only because she's too big to see you. You have a slight affection towards her, but you never tell anyone because you're afraid of what she'd think about you. Usually the pred.
Sarah: Your younger sister, 18 years old, darker skin and a little bit smaller than your big sister. She's got a huge crush on you, but never told you because she, too, is afraid of what would happen if she did. Usually pred.
Minney: Your older mom, light skin, 33 years old, got a penis and some big boobs. Usually pred.
Samantha: Your younger mom, dark skin, 30 years old, got a penis but smaller breasts. Usually prey.
Dory: Your GF, she's an alien, 17 years old, blue skin and huge breasts. Loves being prey.
Katie: Your BFF, she's an alien too, same species as Dory, lighter skin, 20 years old. Secret crush on your sister, Sarah. Loves being pred or prey.
RULES: No hard vore. Only rule. Digestion is alright, anything goes, just no hard vore.
