"Yeah, Daddy, who's better, Dulcie or me?"
As I woke up, I recalled that was the last thing my older daughter, Carolyn had said before I had drifted off to sleep, with her sprawled around me in my bed, and her eighteen year old sister Dulcie standing in the doorway.
The two girls were both competitive cheerleaders, but it was rare to see them treat each other as rivals. Perhaps it was Caro's shock at walking in on me bouncing on Dulcie's bed, entertaining not just my younger daughter, but Carolyn's friend and former classmate Jeanie, combined with Dulcie's only slightly lesser surprise later to find Carolyn getting even by using me to deflower herself.
So I had to wonder, in the waking instant before I opened my eyes, whose warm mouth was enveloping my hard cock right down to the root. Whoever it was, her fingers were rolling my balls and caressing the base of my shaft whenever her mouth rose to hold just my helmet within her lips, tongue bathing me, teeth nibbling gently around the ridge of my head. I decided not to open my eyes just yet. Instead I reached down and stroked some smooth hair. Still not a clue which girl was blowing me.
"Relax, enjoy it, and don't over-think it."
These wise words might have been just in my mind, or they might have belonged to Carolyn, in which case, since velvety tongue was rolling around my balls, would mean that it was her younger sister performing the oral sex. But then a head lay on my shoulder, and something about the size and shape made me think it was Dulcie who proceeded to kiss my neck and nibble down to my nipple.
Whichever daughter was giving me the wake up hummer had once again opted for good old fashioned deep throating. I could feel just a hint of lips and teeth, picturing a wide open mouth surrounding my cock as she sank her nose into my nest of hair, only to rise quickly, kiss my pre cum coated tip, and then repeat the motion. I assumed that the fingers which started massaging my scrotum must belong to the same young woman sucking on my nipple.
I began to stroke each girl's back, my hands flowing along their lithe flesh, but still this gave me no clue who was performing which role. Their similar hairstyles -- straight, just below the shoulders, suited for a perky cheer babe pony tail, added to my sweet confusion.
"How can I judge who's better if I don't know who is doing what?" I muttered out loud.
The mouth lifted off my cock, and both girls shifted on the bed, giggling, in unison, they spoke the same words, more like twins that an eighteen and nineteen year old.
"No one told you that you had to keep your eyes shut, Daddy. You decided that yourself."
Finally, I peeked through my eyelids, the sun filtering into my bedroom. Carolyn was perched on the edge of my bed to my left, one leg dangling behind her towards the floor, as if she was not sure whether she was coming or going. Her beaming grin suggested though that she had enjoyed coming earlier when I had deflowered her. Her erect nipples hinted that she was ready for more. I felt my cock bobbing up and down in anticipation.
That meant Dulcie was on my right. Shifting my gaze in her direction, I saw that she was more aggressive, as usual, straddling my thigh, her eyes focused directly on my cock. Her slight rocking motion made her tits wobble, begging to be kissed, fondled, nipples nibbled. She began running her fingers through my belly hair.
My two daughters swivelled their heads toward each other, and again spoke in unison.
"Monkeys bounce on the bed!" they giggled as they shouted, just like when they were kids.
If Caro had any reluctance, she shed it in that moment, pushing off the foot on the floor to jump on my mattress with gusto, while her sister, more restrained for once, humped my leg. I could feel that her pussy was still damp, or perhaps, wet again from her own expectation of more sexual exploration. I just lay still for the moment, watching how my beautiful girls jiggled just a bit, their nipples seeming to extend with each bounce.
Carolyn bounced a bit awkwardly, her knee striking my thigh roughly, and almost fell. Her hand shot out instinctively, grabbing her sister's shoulder for stability. There was no sexual intent, but the result was electric. Dulcie leaned forward in response, and without a word their lips met, their mouths opened, their tongues intertwined. I had never suspected that this would happen, yet when it unfolded, it seemed totally natural.
My cock throbbed even harder, and I cupped it in my palm, lightly stroking it to try to calm myself. I could not remember ever being this turned on. My balls drew up tight against my groin, and I knew that I needed to be careful not to explode while watching, because my daughters still needed me to judge the contest as to which of them was a better fuck. Even in perversity, they had such a competitive spirit.
At that instant, though, they were too busy exploring each other to fight. Carolyn raised her free hand and stroked her sister's hair. Dulcie in turn grasped Caro's hair in both hands, holding their faces together in that fierce kiss. Then Dulcie's left hand dropped down, caressing her sibling's back. I could hear Caro moaning into Dulcie's mouth. They shifted closer, their nipples brushing against each other, and then their young firm tits mashed together, so that from my reclining vantage point, it was hard to tell where one daughter ended and the other began.
I was struck by how similar their beauty was. Carolyn's slightly greater ripeness was offset by Dulcie's freshness. If they remembered to insist on me picking one as "better", looks would be even. They had not, of course, been talking about looks. They wanted me to pick which was a better incestuous fuck bunny, which was better at bouncing on the bed. That meant points for cock sucking, and fucking, but also for the playfulness, the teasing, the seduction, the hand-job, the rubbing, the kissing.
My balls loved those thoughts, taking my enumeration of the judging list as promising fresh performances. My brain was shocked that I was even considering either possibility. The conflict was resolved quickly, as I decided that I should just blame Jeanie. I had been doing fine at resisting further fucking of Dulcie until that slut had intervened, and Carolyn would not have wanted to get even if she had not witnessed my threesome with those two. Without Jeanie, my initial slip with Dulcie could have been laughed off as an accident, and forgotten. In fact, it was Jeanie's summers of flirting which had got me attracted to young women to start with.
Who was I trying to kid -- the fucking with Dulcie had been incredible. No man could have forgotten that. And now that I had done a second round with Dulcie, I really ought to be thanking Jeanie. That, however, would have to wait for another day. Today, I knew, would be filled by my delightful darling daughters. Sometimes it seemed that, like her mother, Carolyn could read my thoughts. Just as I dreamed of Jeanie, Caro came up for air, breaking off kissing her sister long enough to glance down at my filly stiff cock, and smile beatifically at me.
"I really do need to thank Jeanie for more than just seducing you, Daddy," she panted. "If I hadn't seen her kissing Dulcie, I would never have had the guts to try it."
She turned her face to look at her sister.
