Silence

Sierra smiled. "Ok. I got it. Silence is a 'yes'"

Abby didn't respond. She didn't know if that was true. It might be.

The next day, she looked for any evidence at all, that Sierra had actually been with her parents, but everything seemed normal. Breakfast seemed normal. Then they did some Christmas shopping, came home and made gingerbread houses. It was almost comically wholesome. She'd never seen Sierra do anything quite so wholesome. Although if there was an undercurrent of perversion, that would be more Sierra's style.

Then again Sierra had made up stories before, like the time she said she got extra credit by showing up at their Calculus professor's office wearing a schoolgirl outfit and telling him he could slap her around. That surely wasn't true.

The longer the day went on, the more Abby felt certain that the whole thing was just Sierra having a little fun with her.

Until it was time for bed. They climbed in together and Sierra looked her seriously in the eyes. "Well..." she said. "Do I need to wait for you to go to sleep? Or can I go now? They're waiting for me."

Abby didn't entertain it. "Sure you can go, and hide for a few minutes and pretend like you're fucking my parents and then come back and tell me tales."

Sierra smiled wickedly. "You want to hear a tale? Last night when I sucked your dad's big hairy cock, I called him 'daddy' and when I spread my legs for your mom's eager tongue, I called her 'mommy.' Tonight I'm going to convince them to call me 'Abby.'"

Abby squirmed. "This isn't funny anymore. It wasn't funny to begin with."

"It was never meant to be funny. I'm just trying to get some play." Sierra said plainly.

Then, feeling determined, Abby pounced on her girlfriend in the bed and slipped her hand between her thighs. Sierra moaned. "What, am I not enough for you?" Abby asked, her wet fingers quickly finding Sierra's swollen clit.

"Of course not." Sierra hissed. "You know one person will never be enough for me." Then turned the tables, thrusting upward in one motion until Abby fell off her, then jumping on top and straddling her, pinching and rubbing her clit.

Abby's mouth dropped and she let out a silent scream. Her hands slapped at the mattress below her. This was not unusual. Abby could make Sierra feel good in bed, but Sierra made Abby absolutely wild.

Sierra leaned into her girlfriend rubbing hard and fast "Now... I'm going to go fuck your parents. And you know what you're going to do?"

Abby's eyes flitted back in her head. When it came down to it, she knew Sierra called the shots. "Wh..what?"
