Send the guy back home

Putting on a patient and demanding look on her face, Emma headed to the bathroom to stand leaning against the door post with her arms crossed below her chest as the door opened and Jeff stepped out.

"Oh, fuck?!" He grunted in surprise as he found his girlfriend's sister staring into his face. She was almost as tall as himself, as he was slightly below average in height for a man, and her tussled long red hair made her appear even taller. "W-what the fuck, Emma...? What are you doing here?"

"I think that's my line, lover boy!" She scowled back at him, both of them keeping their voices low, while she pointed her thumb back towards her sister's bedroom. "And what the heck do you two think you're up to?"

"Well, just a little experimenting...?" Jeff mumbled, looking embarrassed but also rather excited. "It's, you know, our first try with something like this... And I think she's really into it!"

"Nuh-huh...?" Emma nodded her head, but didn't look in the slightest impressed. "And I think it would be a lot harder to explain this to me and my sister's parents, than just to me."

"Aww, come on!" He tried to object, realizing where this was headed to. Perhaps he'd had some slight hopes for some kind of bondage-threesome with both his girlfriend and her sister, but Emma made sure they idea was quickly taken right out of him.

"Just leave now, and I won't let anyone hear about this." She told him coldly, pointing to the stairs, and then followed him as he reluctantly started heading down to the front door. "You're lucky I didn't catch you in the middle of the act. I'd probably put my foot to your balls, before you'd even had the chance to explain it was just a 'game'."

"Ouch..." Jeff agreed, with a slight wince, but then turned and tried to plead with her once again just as they reached the door. "Come on, Emma... You know I'm not a bad guy! Don't ruin this for me, and for Hannah!"

"I think you ruined it yourself." She cut him off without remorse. "By the same time you tied my sister to her bed, without even checking if there was someone else at home..."

"Oh, come on...!" He tried again, but didn't resist as she shoved him through the door. He did call her 'bitch' under his breath though, which rewarded him with a slap across the back of his head before the door was closed and locked behind his back.

Emma would've slammed the door much harder, if it wasn't for the plans already forming in her mind for her pretty little sister. She waited a few moments, allowing herself to calm down again, before checking that Jeff was off for sure, and then headed quietly up the stairs.

She found Hannah just like the last time she saw her, still tied spread eagle to her bed and completely naked apart from the blindfold covering her eyes. Again she could feel her cock twicthing at the sight, and she knew she'd have to sate it's hunger for female flesh, one way or the other...
