“Damn, Rob! Swapping girlfriends for the night was a great idea,” Mike said.

“I know, right? The same pussy all the time can get a little boring.”

“I thought they’d balk a bit more at making out with each other while we fuck them though. I mean, they are sisters.”

“Yeah, but I’m sure they’ve had to screw each other plenty of times since the Sexual Service Act went into effect last year.”

“Mmm. Yeah, Rob is right. We’ve been stopped in stores, on campus, in the street, and even in an elevator before once someone figured out we were sisters, they just ‘had to’ see us eat each other out, right there in public,” Rob’s girlfriend said.
