Heather looked at her and mouthed, “What the hell?” to the older girl.
In response, Abby just blew her a kiss, and took another bite of vegetables.
As Abby’s foot made no sign of retreating, Heather looked at Jeff and said, “You know what, Jeff, this was really great, but I think I think I’d like some dessert now. Can we go get ice cream?”
“Or you could stay here and have something just as sweet,” Abby offered suggestively as her foot climbed higher and higher.
“Would you like to stay here and have something sweet with us, Heather?” Jeff asked with a charming smile.
Heather scooted back from the table, letting Abby’s foot fall to the floor. She looked at her boyfriend questioningly. “Okay guys? What is going on? First that kiss. Now your sister is making a pass at me under the table? You guys are fucking with me, right?”
“Oh, we’d like to fuck with you alright,” Abby cooed.
“If that’s something you’d be into,” Jeff added.
“But…but, you’re brother and sister!” Heather argued.
“Not today,” Jeff smiled. “Today is sort of a cheat day. Tomorrow might be too, who knows?”
“I don’t understand what that means,” Heather said.
“It means,” Abby said, “That I’m fine with you fucking my hus- sorry, ‘your’ boyfriend today, as long as I can be there to help.”
Heather was temporarily at a loss for words at the offer. She’d never been invited to a three way before. That’s what this was, right? Yeah, it would be. She’d be fucking Jeff, and Abby would be there, and she’d be ‘helping,’ which meant she’d be participating. So yeah, that’d be a three way. She thought she’d have to wait until college for one of those. She looked at Jeff to see his thoughts on the matter.
“My sister and I have talked it over,” Jeff explained. “As you know, she’s recovering from a failed marriage, and she’s looking to get back in the saddle again. I think this will help her out.”
“Having sex with her brother?”
“No, no!” Jeff said with feigned shock. “With both of us! And as I said, this is a cheat day.”
“What does that mean though!”
“It means I’m your boyfriend, so it’s not cheating. And Vickie- I mean, Abby, is my sister, so…”
“That doesn’t make any sense!”
Abby pulled her white shirt over her head. It had been obvious that she wasn’t wearing a bra before. And now it was really obvious. “So, you want me just to fuck Jeff without you?” she challenged.
“What!” Heather balked.
But before she could protest further, Abby stood up and put her tits in Jeff’s face. Jeff didn’t shrink back, but began kissing and fondling his sister’s boobs.
“In or out?” Abby asked.
Heather narrowed her eyes at Abby. She didn’t know what these two perverts were playing at, but whatever it was, she wasn’t going to lose. In a quick, fluid movement, she pulled her dress up over her head. In another second, her bra was falling off. She moved to the other side of her boyfriend, her slightly smaller tits on display for him. He turned to her, and put his mouth on them. Heather arched a brow in Abby’s direction as if to say, ‘you’ll have to do better than that, cause he likes mine better.’
