The twins are home!

It didn’t take long for Dave to cum again, only this time, his mom wasn’t too keen on being in the firing line. She continued to pump away at it with one hand while the other fondled his balls, she just pointed it in the direction away from her. It wasn’t as big as his first load, but it was still enough to make her slender fingers slick and slimy.

Once Dave finished, he released her breast and melted into the couch once again, both of them breathing heavily.

He could tell by the look in her eyes that she was still fascinated by his cock, even as it began to go limp in her grasp.

Before he realized it, his mom was standing up from the couch and making her way to the kitchen.

“I’m going to go wash my hands.” She said as she reluctantly let go of his cock. “If you don’t mind, clean the couch while I’m gone.”

Light-headed and dazed, Dave turned to the side to see where his load had spurted onto the arm of the couch, and he rolled his eyes as he watched his mom’s big bouncy butt walk out of view.

He felt spent, and his cock went completely soft after a moment.

Even as he tried to stroke its sensitive length back to attention, it didn't have the strength to get back up.

That should be easy to fix, but he would have to risk letting his mom hold the wishbone for it to work. Which, in theory, shouldn't be a big deal. Dave could use the wishbone's power to have her take it from him just to make a specific wish or two before immediately handing it back to him.

Or...

Maybe there was simpler solution.

However, as soon as an idea came to mind, the front door opened, and Dave's heart skipped a beat from the unexpected noise.

"We're home!" Dave's sisters called out, as they usually did.

When they entered the living room, they took a look at their brother on the couch and stopped dead in their tracks.

Alyssa looked confused, and Amy looked disgusted.

They were pretty natural responses to seeing their naked brother home from work so soon with his big limp dick resting on his thigh for anyone around to see.

While Dave and his mom were about the same height at 5'9, Amy and Ally were a bit shorter at 5'3. They had just turned 20 a few months ago and were in their Junior year of college, which they were arriving home from. Aside from their identical faces and slender figures, it would be hard to mistake the two for one another.

Alyssa's hair was dyed jet-black and styled in a pixie-cut, while Amy's hair was a long natural blonde color and cascaded down her back just past her shoulders as a navy-blue headband held it all back.

Alyssa's make-up was nonexistent aside from a bit of black blush and eyeliner, while Amy's face was expertly painted with a few different shaders that brought out her cute facial features.

Alyssa's attire consisted of a long-sleeved black shirt, dark jeans held by a thick leather belt with metal rings in it, as well as a pair of black Converse with white laces, while Amy was wearing a lime-green tank-top, faded skinny-jeans, and a pair of navy-colored flats that matched her headband.

"Everything is normal." Dave said, glancing between them with a nervous look on his face. "Don't freak out."

The bone pulsed, then pulsed again.

They stood there for a minute simply staring at him in silence for a long moment before glancing at each other.

"Why would we freak out?" Alyssa asked her sister in confusion. "Am I missing something?"

"Well, our brother is naked on the couch in the middle of the day, so I wouldn't exactly call that normal." Amy responded, crossing her arms in suspicion. "But yeah, I don't see a reason to make a big deal about it, as weird as it is."

"What do you mean?" Alyssa asked. "What's weird about it?"

"... What do you mean?" Amy asked. "What's not weird about this?"

"I don't know, seems pretty normal to me."

"When does Dave ever sit around the house without any clothes on?"

"I don't know, all the time?"

"No, he doesn't?"

With a furrowed brow, Dave's eyes danced between them as they discussed the situation. It took him a moment, but he quickly figured out what might be going on. If the wishbone had certain limitations about changing oneself, then it probably had other limits too, like only being able to affect one person at a time.

He was lucky that his eyes weren't focused on just one of them when he used the bone's power, Dave realized.

Then again, it's not like he wouldn't have been able to fix the situation immediately afterwards.

Just then, their mom stepped back out into the living room

"Oh, hi girls." She said, wiping her damp hands on her immense bare breasts. "How was school?"

"Good." Alyssa said with a shrug. "Same old, same old."

"Uh..." Was all Amy managed to say, her expression riddled with even more confusion as her eyes locked onto her mom's gigantic bust. "M-Mom?"

"What's up, sweetie?"

"You look... different." Amy said before turning to her brother. "What's going on, Dave?"

"Like I said, everything is normal." Dave shrugged, and the bone pulsed.

"Yeah." Alyssa agreed, placing her hands on her hips. "You're the one that's acting weird."

"I-..." Amy still looked confused, but the expression lightened a bit after a moment. "You're right. I'm not sure what I was thinking just now."

"Mom." Dave said, turning towards the kitchen's entryway. "Now that everyone's home, you should go get dinner started."

The bone pulsed.

"Good idea." Their mom said, her gaze clinging onto Dave's cock from afar as she idly rubbed her big volleyball tits. "What are you kids hungry for?"

"Spaghetti sounds good." Amy beamed.

"Ooh, yes please." Alyssa agreed.

"Sounds good to me too." Dave shrugged.

"Alright, it should be ready before you know it." Their mom said, reluctantly turning away from her son's big cock and wandering back into the kitchen. Dave couldn't help but stare at her big jiggly rump as she walked away once again.

"Sweet." Alyssa said, then began to turn towards the hallway. "I think I'm going to take a quick shower and change."

"Don't use up all the hot water, I want one when you're done." Amy said, following after her. "Unlike you, I actually do sports, and I feel ripe."

“Hold up one second.” Dave said as he stood up from the couch. “Why don’t we all take one together?”

The twins stopped and looked at each other, exchanging disapproving glances before turning back to Dave.

“Now that would be weird.” Amy scoffed.

“Yeah…” Alyssa uncomfortably agreed.

“No it wouldn’t.” Dave said to Amy, and the bone pulsed. “In fact, it’s a great idea.” Dave said to Alyssa, and the bone pulsed again. “What do you say?”

The twins looked at each other again and shrugged.

“Well, now that you mention it…” Alyssa said, smirking.

“It would help save on hot water.” Amy said, turning back to Dave as he approached them, her eyes watching his big half-erect dick as it bobbed around with every step he took.

“Come on, then.” They both said, and the three left for the home’s main bathroom together.
