A missing father and a sticky surprise

About a week after the horny pool incident, I had an odd realization: my father was... Absent.

I don't just mean that he was spending a lot of time out of the house. That had always been the norm, given his job responsibilities and workaholic personality. This time, though, he was completely gone. I hadn't seen him in days--Not since the morning after Mom drank my potion.

As soon as I had that realization, I checked the garage--And found his car. That's when "mild curiosity" started to morph into "quiet dread." If he wasn't at work, where the hell was he? And why hadn't anyone said anything?

After taking a quick toke to calm my nerves, I decided to ask my mom. I'm freaking out over nothing, I thought as I made my way downstairs. He's probably just on a business trip, and nobody bothered to tell me. It's happened before... Probably. Maybe. I think.

I found Mom in the kitchen, making herself a snack. She turned and gave me a friendly look when I came in, leaning against the counter and cocking her wide hips. She was looking ravishing, in a tiny crop top that showed off her big, round tits while leaving her navel exposed... Quite unlike her usual style, but I was too busy appreciating the view to question it. The only damper on her skimpy outfit was the baggy sweatpants she was wearing. Ugly, thick, grey... Probably some of Dad's old workout clothes. They even had a big, dark stain on the thigh!

"Morning, sweetie," Mom replied, smirking. Did she catch me checking her out?

"Uh, hey--You haven't seen Dad, have you? Where's he been, lately?

"Your father's never around," she chuckled. "I can't seem to make him spend time with me--Normally, anyway."

"Um, sure, but his car--"

"Why don't you ask your sister?" Mom was still giggling, laughing at some private joke while she gestured towards the living room. "I'm sure she knows where he ended up."

With a nod and a shrug, I went off to find Ella. Entering the living room, it took me a moment to spot one of her dainty feet dangling limply over the top of the couch.

Walking around for a better view, I saw that she was sprawled across the seat, one slim, bare leg in the air. She was wearing booty shorts and a T-shirt, which was... Stretched...

It took me a moment to process what I was seeing: my sister's belly was distended, as though she was pregnant or a competitive eater or something. The second option seemed more likely, given the slimy, off-white sheen covering half of her body: she looked like she'd had a bucket of yogurt poured into her mouth, and only managed to swallow half of it. Her mouth was hanging open and drooling a thick trail of goo, which soaked through her shirt to outline her small, perky tits. The mess extended from her bulging belly button to her forehead, with plenty of collateral damage dripping onto the couch.

"Wha--What the fu--"

My swear was cut off as I felt a strong hand clap me on the shoulder. I spun around to see Mom, staring down at Ella with a huge grin on her face.

"Better not wake her," she whispered, her voice quiet but firm as her eyes stayed fixed on her daughter's body. "Ella's had quite a morning... She needs time to digest."

Stifling another giggle, she took her hand off my shoulder--Only to give my ass a meaty slap. She left it there after the spank, and started guiding me back to the kitchen.

"Maybe you can help me with something, dear," she continued softly. "Your father left me with all this special cream, and I don't know what to do with it all! Your sister ate as much as she could for breakfast, but--"

Before she could finish her nonsensical little speech, the doorbell rang.

"Oh? I'd better get that before Ella wakes up," Mom giggled, without missing a beat. Then she pinched me on the cheek, licking her lips as she eyed me up and down. "Go relax, sweetie. I don't need you right now."

With that she practically skipped into the front hall, the swell of her voluptuous ass visible even through the sweatpants. Swallowing hard, I decided to retreat to my bedroom.

As I climbed the steps, I heard Mom talking excitedly, then a younger woman's voice... Claire?
