You would definitely fuck Liz raw

"Of course I would fuck Liz raw," you say to Sara. You wonder if you should up the stakes, but before you can make a decision you are speaking anyway. "I would fuck any of the three of you raw."

"Good," Sara says, apparently satisfied. "Because Liz asked if I would...mind...if you were the father of her child."

You almost spit out your sip of beer.

"Well," you say to Sara when you recover, "what did you tell Liz?"

Sara gives you a naughty look. "I told Liz," she says, "that you'd be a wonderful lover and that I think you have sexy...genes. And that you'd be a great father, if she wanted you to be. And she should go for it."

"And do I have your permission," you ask, giving Sara a mischievous glance of your own, "to find your big sister at your wedding, flirt with her, let her seduce me, find her just before the wedding and bend her over in the dressing room? To finally push my hard cock into her tight body again and again until my cum explodes deep into her fertile, willing, dripping pussy?"

Sara's whole body shivers with what can only be lust.

"You, sir," Sara says, "Have more than my permission to fuck my sister at the wedding. I want you to enjoy her body. Give her what she wants."

You both sip from your beers. "In fact," Sara says, "I have to admit it's kind of hot."

"Which part?" you ask.

"Making a baby. Having siblings," she says. "God that's hot. I would have loved to have fucked you and your sister."

Your eyes get wide. You had always suspected that Sara was attracted to both men and women, but you never had confirmation until now. "Well, my sister is my plus-one," you say. "But since you won't have much opportunity to bed her before your wedding, I guess you'll just have to live through me."

"Mmmm," Sara says. "Cheers to that."

Your drinks clink together.
