One At A Time

"Okay girls, are you sure you want to do this?" I asked, "Harem or no, Dutch ancestry or no, you are my sisters. I never want to hurt either of you. If you want to do this, it would be my pleasure. But if you have any doubts, any at..."

"I WANT THIS!" Gwen shouted, jumping off the couch to grab my arm.

"No doubts!" Beth echoed, grabbing my other arm.

"Okay. That leaves one final question. Who goes first?"

"Me!" both girls exclaimed, then after a pause, "Her!"

The more things change, I think, grabbing a coin off of the coffee table. "Heads, Gwen, tails, Beth."

I flipped the coin, and...

"Yes!" Beth cheered, seeing the coin's result.

Gwen's disappointment was palpable. But, being the good brother I am, I'm wasn't about to let her stew. I held on to her hand, tugging her along as I lead Beth to the couch. "Come on Gwennie. Mom and Farah are a little... preoccupied." Nodding at my mom under my girlfriend's dress. "I think I'm going to need your help with Beth. You want the right one? I'll take the left." Before I give either twin a chance to realize what I'm proposing, I ran my tongue across Beth's large, pink nipple, causing her to knees to buckle.

"OOooh FUCK. John, what the fuck was that?" My shocked sister practically screamed.

"Not only did your Indian blood give you these massive melon sized melons, your tits are now hyper sensitive. If one lick was able to set you off like that, what do you think two mouths will do to you?" A quick wink at my other sister snapped Gwen out of her surprise, and as one, we both fell to our knees and began our **** on Beth's gigantic tits.

The effect on Beth was almost instantaneous. The two of us had trouble keeping our mouths attached to her nipples as she bucked and jumped as orgasm after orgasm raced through her veins. "AIIIEEEE! YES! SUCK YOUR BIG SISTER'S BIG TITTIES! THIS FEELS SO GOOD!"

An indignant Gwen couldn't help but comment at that, "Big sister? I'm older than you."

"And I've got three years on both of you."

"DON'T CARE! Get those hands and mouths back on my tits. NOW!" With that, she reached out and grabbed Gwen's head, forcefully pulling her into her heaving chest. The entire family was caught by surprise as the sensation of having someone else's fingers running through her hair set Gwen off on her orgasm.

"Oh Gwen, that's right. Now you like having your hair played with, don't you. I might have to remem... why are you looking at me like that?"

Gwen and Beth had always had a bit of a competitive nature. Mostly in good spirit, but neither ever liked having the other get the upper hand. Based off the look in Gwen's eyes, she wasn't happy about her sister throwing down the gauntlet. Using her newly obtained strength, she easily pulled herself out of Beth's grasp. "John, I'll take care of Juggs McGee's tits. You get those pants off and put that dick to use." With that, she easily moved Beth around on the couch, lifting her as if she weighed nothing. Settling in behind her sister, Gwen whispered in Beth's ear. "You didn't think I'd let you win that easily, did you?" With that, Gwen draped her long, soft hair over her sister's chest, covering the massive orbs in silky smooth strands, setting them both off again.

Almost tripping as I stepped out of my pants, I muttered, "You girls...you're on birth control right?"

"Well, the Dutch ancestry means inbreeding isn't really an issue, but yes, they're protected," came the voice from under Farah's dress.

"Okay then. Gwen, Beth, you guys ready?" I asked.

Both girls were beyond words. I got a slight nod from Gwen, but Beth was miles away. The frantic please I saw in her eyes was pretty telling though. "Stacy, I think you're going to want to see this."

With no further preliminaries, I aimed my dick at Beth's dripping slit, and slowly, steadily sank all the way until my pubes were mashed up against hers.

Holy shit... I was fucking my sister. This trip home had gone so completely astray from my original plans.

"HUHHGGHH! YESSSS!" Beth screamed, "Fuck me harder John! Fuck your sweet little sister! Oh shit, Gwen, your hair, it feels so good on my tits! ARGGHHH! Another? Holy shit. I can't stop cummin...urg?"

I had been so focused on the bouncing orbs in front of me I hadn't been paying attention to Gwen, who had apparently had enough of Beth's screaming, and had used some of her hair to create an impromptu gag. Beth's moaning through the gag had Gwen shivering in lust. "She's close John, I can tell. Give it to her. She wants it hard. Fuck her into the couch." To accent her point, Gwen reached around her sister and firmly grasped Beth's tits, harshly pinching both nipples. The scream that came through the gag was audible, but definitely not intelligible.

I was relieved to hear Gwen's cheers. I was approaching my limit as well. I didn't know if this was Beth's first time, but I was going to do everything I could to cum with her. Stroking fully in and out of her pussy with each pump of my hips, I sped up as much as I could. "Beth. Your brother is fucking you. I'm fucking your. Tight. Little. Pussy. Does my cock feel good in you? Do you like how your big brother feels, so deep in your pussy? You know I'm about to cum, right? I'm about to cum deep inside my little sister. Do you want that? Do you want your brother to fill you up with his cum?"

Even through the gag, the muffled "YESSSS!" was clear to all in the room. With that, I felt her constrict even tighter around me, in the middle of a massive orgasm. I was at the cliff of my own, so I thrust as hard and as deep as I could crushing my chest against hers and emptying my balls deep into her tight sheath.

"Oh fuck, John, that was so hot." Looking behind me, both my mom and Farah had shed their clothes and were staring at us with their mouths wide open. Farah was furiously pumping her fingers in and out of her pussy, while my mom had been filming the whole thing. I couldn't help but laugh at the whole scene. The family photo album was going to be going in a different direction, it seemed.

"So...when is it my turn?" came Gwen's voice from behind her panting sister.
