Talk to the sisters.

You decide to confront the sisters now rather than later before things could get more awkward.

"Hey," you greet the girls on the front porch. Loretta stands meekly behind you, looking around your shoulder. "Val and Amie are bringing the beer downstairs."

"That's good," Connie replies, unable to look you in the eyes.

"Yeah, the four of us need to talk," suggests Ellie. You notice that she is no longer the playful minx you met at the bar but rather the older sister.

"I guess you know about us," you reply, glancing at Connie.

"Not until I saw Connie a couple minutes ago. I knew that something special happened to her last night because she was smiling all morning. It wasn't like her usual mornings after her trysts with Loretta." Ellie smirks at Loretta.

"You know?" Loretta gasps, turning red in embarrassment.

"Don't worry my parents don't know," Connie assures her.

"From the way she smiled I knew she got laid," Ellie said, smiling at her younger but bustier sister. "I'm glad you're no longer a virgin, sis. You shouldn't please Daddy's old fashion morality by saving yourself for marriage. You should please yourself first."

"You're not a virgin either?" Connie asks.

"You're more naive than I thought," Ellie says, taking her sister's hand lovingly. "I lost my virginity when I was sixteen! I just tell Daddy I never had sex just to keep him from shooting my boyfriends!"

"So you're not upset at me for taking your sister's virginity?" you ask, feeling relieved at the relevations.

"Of course not, especially if you made her cum like you did with me at the bar," Ellie replies. Connie and Loretta stares at Ellie with mouths agape. "What? I love cock!"

"So do I," Val interrupts, opening the screen door. Everyone looks over at the brunette with Amie behind her.
