Go for Sara's nice ass.

I think Sara's ass looks way too inviting to leave out.

As she's slowly coming down from her ecstasy I pull out of her cunt and start pressing my cock against the hole above.

”What the fuck are you doing!?!” Sara shouts angrily, pulling away from me.

”I just wanted to fuck your cute little ass...” I said with a guilty voice.

”Nobody gets to do that” Sara said, now a bit calmer. ”My ass is exit only!”

”You see,” Tara explained, ”in our family we've come to a sexual agreement based on our personal preferences. Since we're usually attracted by the same men, and they seem attracted to all of us, we've found sharing to be the only viable way.”

”As you've noticed by now,” Sara continued the story, ”Tara is the family's oral resource, always willing to suck a hard dick and have her pussy eaten. She loves the taste of sperm and get quite cranky if she doesn't get a drink each day. That's one reason you're wearing a condom right now; to collect the sperm for her to drink. Right sis?”

”Correct. My mouth is the only place where I let cocks in. My pantyhose help in guarding against unwanted intrusions. Sara, on the other hand, provides a hot pussy able to satisfy even the most craving dicks. We make sure it gets its fair share of exercise.”

”Yup!” Sara filled in. ”I don't do blow jobs, but might use my hands to get a cock going if my attire doesn't do the trick on its own. Then I try to avoid fucking when I have my period, other than that I usually get at least a quickie every day.”

”Mum, on the other hand, is all tits and ass,” Tara went on. ”That's where you'll get to fuck a tight ass if you want to. Just don't forget to wear a condom for me.”

”So how do we finish you off?” Sara asked. ”I'd love to feel your hard dick inside my pussy some more, and milk you dry when you come.”

”I wouldn't mind a sixty-nine” Tara said. ”Then I can have all that yummy sperm directly from the source. I expect to get more by tomorrow anyway...”

”Or mum could get the last of you for now, should we seek her out.” Sara continued. ”But I think she'll be happier if you're more alert the first time you get to do her.”
