“You were both pregnant at the same time,” she says, more a statement than a question. Both women nod and after a moment’s pause, Kristina adds, “What about Angela?” Kristina is referring to her 16-year-old sister.
“Well…” her mom clears her throat. “It worked so well the first time, and we didn’t want you to be an only child, so we did it again a couple of years later.”
“Swapping partners, again?” Lauren asks.
“Yes,” mom says.
“What about now, when the four of you go to the cabin?” Lauren asks and I bet mom wishes she had never promised that she would always tell us the truth no matter what we ask.
“Not that it is any of your business,” mom starts meekly. “But sometimes a marriage needs something to keep it from getting stale,” mom looks at Mrs. Andrews instead of us as she speaks. “We’ve found a way to spice up our marriages without any hurt feelings or repercussions.” We all sit quietly, no one quite sure what to say.
“Now do you two believe us that you shouldn’t be seeing each other?” mom asks.
“We need to think about this,” I answer, looking at Kristina who nods solemnly.
“What’s to think about?” Mrs. Andrews asks. “It’s incest! That’s wrong!”
“I need to think about who my father is!” Kristina answers. “All these years, I thought dad…”
“Your dad is still your dad!” Mrs. Andrews admonishes. “It isn’t sperm that makes a dad, it’s who raises you!” Mom is giving me an imploring look, hoping I’ll make some sort of declaration.
“I don’t think this is so easy,” I say. “You’re telling us that incest is wrong, but wife swapping isn’t?” I ask sarcastically. “I think it’s a little late to take the moral high ground, don’t you? That train has already left the station.”
When no one says anything for a few minutes, I stand up and grab Kristina’s hand. “We’re going to go out for a while and talk about all of this, okay?” I ask. Mom and Mrs. Andrews both look worried so for their benefit I add, “Don’t worry, Lauren will be with us.” Lauren is almost able to hide her smile.
“Love you, Mom,” I say, moving around the table to kiss her on the cheek. “Goodbye, Mrs. Andrews.” The girls say their goodbyes and we head to my car.
“I almost burst out laughing,” Kristina says when we get into the car. “OHMYGOD! You’ve been fucking your sister!” she mimics Lauren and then bursts into laughter.
“That was classic, Sis,” I tell her. “How do you feel about all of this?” I ask, looking over at Kristina.
“I don’t see where it changes anything,” she responds instantly, placing her hand on my thigh. “Maybe that’s why you were attracted to me,” she adds with a twinkle in her eye. “You do seem to have a thing for incest.” We are all laughing again.
“Seriously,” Lauren says. “I think this does change things. We were hiding the incest behind your relationship but now that is incestuous too. What are we going to do?”
“Call Alex?” I tease. Both girls hit me at the same time.
“Not funny, Brandon!” Lauren says, but she smiles anyway. “What were the odds that the one person we picked to include would be our half sister?” She adds as I turn the car into my driveway.
“Whatever we decide,” Kristina says as I unlock the door, “I need some incest right now.” She’s pulling her top over her head as soon as we walk in the door.
“I know, all that talk about fucking got me horny,” Lauren adds, shedding her clothes as well.
“Everything gets you horny,” Kristina teases, smacking Lauren’s bare bottom as I unsnap my jeans.
“Hey!” Lauren protests, trying to return the slap but Kristina turns to the side and she barely connects with her hip.
“Eating cereal makes you horny!” Kristina says, hopping back out of the way. “Answering the phone makes you horny!” The naked girls are hopping around the room, laughing while Kristina teases my sister… uh, our sister, I mean. My cock responds to these two naked beauties playfully prancing around trying to smack each other’s bottoms. And very sexy bottoms they are.
“Breathing makes you horny!” Kristina laughs, plopping down on the sofa so Lauren can’t reach her butt. Lauren straddles her legs, kneeling on the couch while she tries to pry her up off the cushion. They have no clue how sexy they look wrestling naked on the couch.
“Get these things out of my face before I bite them,” Kristina laughs, swatting at Laurens tits, which are dangling dangerously close to Kristina’s face.
“You’d probably like to, wouldn’t you,” Lauren teases, shaking her beautiful tits back and forth in front of our half-sister.
“It would just make you horny!” Kristina laughs, sticking her tongue out and trying to catch one of Lauren’s nipples as it swings across in front of her. Lauren slows her movements, letting Kristina’s tongue barely connect with her left nipple.
My cock hardens in anticipation of Kristina sucking Lauren’s tits. For a second it looks like it’s going to happen. Lauren is staring at her friend, almost like she’s willing her to do it. Her tits have stopped swinging from side to side and just hover near Kristina’s open mouth.
“I wish I had tits like this!” Kristina laughs, pushing Lauren away. “Look at Brandon drooling over them!” Fuck! The spell is broken and she has no clue that I was really drooling over the idea of a girl on girl show.
“I was just enjoying the show!” I respond, trying lamely to recapture the moment. Lauren glances at me like she understands but Kristina is up off the couch and grabbing my hand.
“Come on, Brandon!” she says, pulling me down the hall towards my bedroom. “Time to fuck your sisters.” I’m not going to argue with that. Lauren joins us and I spend the next couple of hours alternating between my two gorgeous siblings.
I devour, tease and fuck them both, eating them to an orgasm each before fucking Kristina from behind and Lauren face to face. These have proven to be their favorite positions. Lauren really likes to kiss while we fuck and Kristina likes how deeply I pound into her from behind.
When I think I’m spent, they give me a joint blowjob that gets me going all over again. They’ve gotten quite adept at trading my cock between their talented mouths. As I watch how close their lips get to each other, I can’t help but think of their earlier actions. Lauren really looked like she wanted to take this farther. I remember how surprised I was when she played with Kristina’s nipple while Kristina rode my cock during the sleepover. When I shoot my load into Lauren’s mouth, she’s not looking at me; her eyes are locked on Kristina’s.
As I take the girls home, we talk a little about our dilemma but don’t come up with any answers. After dropping off Kristina in front of her house, I pull into my parents’ driveway and Lauren and I sit in the car for a few minutes.
“That was very sexy when you and Kristina were wrestling on the couch,” I say, trying to open the conversation without being too overt about it.
“Yeah, that was fun,” she says, looking at me like she wants to add more. “You got really hard watching us, didn’t you?”
“Of course. It was very erotic.” I hesitate for a minute and then figure what the heck. “You enjoyed it too, didn’t you?”
“I always enjoy making you hard,” she says without answering my question. We say our goodnights, our kiss lingering a little longer than usual, neither one of us wanting the evening to end.
