"Don't you want to, baby? Isn't it supposed to be every man's dream to have sex with two girls at the same time? Just look at that gorgeous little body of her, and then tell me you aren't interested?"
I didn't have to look. In fact, I was trying hard not to… Damn, she had a fine ass.
"That's it baby, take a good look… Can you believe she hasn't been fucked in a whole month?"
With Gemma's head firmly clamped between Eileen's legs, a seductive wiggle of her hips was the only way she could convey her desire. Still, the message was clear; after a month of celibacy, my baby girl was in dire need of cock, and was eagerly offering me her fabulous body for a bit of casual sex. It was such an exciting thought that it was outright terrifying. I had to do something to steer this conversation in another direction, before things would run seriously out of control.
"But you are the only girl I want, Eileen." I said. "Just you and me, like it used to be."
"I know what you mean, baby. I've been thinking a lot about us lately. You see, there are so many things I have never experienced, and I'd hate to think I never will… I mean, what I'm trying to say is that I want you, but I need a lover who's willing to try something a little more daring."
There. She said it, as plainly as possible given the situation: I 'only' had to fuck Gemma, and then we'd be back together. The fulfillment of my deepest wish was almost within reach, just one insurmountable obstacle away. As I was mulling over her words, I spotted a loophole. I didn't have to go all the way, I only had to show Eileen I wasn't a prude. There had to be plenty of ways to do that, other than having sex with my daughter. If that was true, this was an opportunity I simply could not ignore.
"I'm not a prude" I replied.
"I know you're not," she assured me, "And this is your chance to prove it."
My lust for the voluptuous nymphomaniac was almost unbearable; the promise of emptying my balls in her tight snatch was too tempting. Although my brain was screaming at me not to do it, I stepped into the room and pulled the door closed behind me.
The air inside the room was heavy with the scent of aroused female flesh. I didn't think it was possible, but I'm sure my cock grew even bigger and harder as I inhaled the pheromone-laden air.
"I knew you'd do it, baby," Eileen smiled, "I could see it. In fact, I've never seen you this excited before. Tell me, is it because of me… or Gemma?"
"You, of course" I croaked, my throat dry as desert sand.
"You're a liar, but I love you."
I was already beginning to regret my earlier moment of weakness. No matter what I did, Eileen always seemed to be three steps ahead of me. I had only seconds to come up with a plan that would ensure the revival of my affair with the sexy nympho, and preferably one that involved as little incest as possible. On top of that, I now also had to devise an exit strategy that would not only be satisfactory for Eileen, but kept my identity a secret as well. However, my mind was a total blank. With all the blood in my body filling my erection, there was too little left to nourish my brain.
As I was standing there with my thumb up my ass, it became increasingly obvious I had to do something. I was still without a plan, and when panic struck, I did the least offensive thing I could think of: placing a single hand on Gemma's compact rear and gently caress the soft skin. I knew it wasn't the smartest move ever, but I had little choice.
I gingerly fondled my daughter's delightfully firm behind for a moment and furtively explored its lovely feminine curves. It was simply impossible not to enjoy the smooth, warm skin underneath my hand, and as I was feeling her up, my paternal feelings were slowly giving way to less wholesome desires. I hated myself, but I couldn't do anything to stop it. It was a good thing that Eileen couldn't see my throbbing cock drool profusely, ready as it was to make that plunge into taboo territory.
While I was doing my best to ignore the effect my daughter's body had on me, oblivious Gemma had no need for such inhibitions. She was moaning lustfully as she twisted and tilted her hips, trying to steer my caresses nearer towards her neglected pleasure center. As much as she wanted me to touch her there, I was determined to keep myself from doing just that. However, it wasn't long before I wrongly anticipated her next move and my hand landed exactly where it shouldn't: right on the edge of her pussy.
As soon as she felt my fingers on her dewy lips, Gemma instinctively pushed back, and before I knew it, the fleshy hood covering her clitoris slipped between my fingers and the soft labia wetly kissed the palm of my hand. My initial response was to yank my hand away from that forbidden place, but I managed to keep it there, fearing that such a reaction would compromise my plans with Eileen. Whether I wanted to or not, I was now fingering my daughter's pussy.
"Yess… just like that," Eileen groaned approvingly, "Feel that hot little cunt, I bet it's dripping wet, isn't it?"
Watching me violate my own daughter was exciting Eileen almost to the point of orgasm, and maybe that was exactly what I needed to do to satisfy her. Figuring I had already crossed this border, I gave myself permission to keep playing with Gemma's juicy pussy until Eileen had come, and then I would quickly have to make my getaway, before this situation escalated any further.
My fingers traced the dainty inner lips of Gemma's seething hot sex and then made their way to the little cowl protecting her sensitive pleasure button. I felt the little bead of her clitoris firm up under the tip of my finger as I circled around the tiny bundle of nerves. An approving moan sounded from between Eileen's thighs, telling me how much she enjoyed what I was doing.
A little higher up, I explored the mouth of her vagina and tentatively dipped a finger into the tight hole. I only penetrated my daughter's pussy up to the second knuckle, but the sensations of her velvety tissues hugging my extended digit were incredible. I had fond memories of how hot and tight Eileen's young pussy was, yet this was a million times better still. If Gemma felt this good around my finger, I could only imagine how phenomenal she would be around my cock.
There was a moral battle raging between my brain and penis, a battle which my brain had little chance of winning. As much as I was trying to ignore the taboo desire I felt for this girl, it was simply impossible. By now I was horny enough to stick my cock anywhere, and Gemma's moist pink pussy was beginning to look alarmingly tempting. Instead of focusing on that much-needed exit strategy, I found myself contemplating whether it might actually be worth violating my little princess in order to renew my affair with her best friend. It was a dangerous thought, and honestly, if I had managed to come up with a way to do it without messing Gemma up for life, I wouldn't have hesitated another second.
Eileen had no sympathy for moral dilemmas. She just wanted to see me perform this unspeakable act of incest with my daughter. She was biting her lip and clenched her fists, fighting to keep off her orgasm as she watched me break down.
"Just do it, baby" Eileen groaned. "Grab your cock and fuck that tight little cunt… you know you want it!"
She was right, I wanted it. Badly. But I couldn't do it; my love for my daughter was still stronger than my lust for her friend. I had crossed as many borders as I was going to. I shook my head one last time and withdrew my hand. It was a pity I had to relinquish this outstanding piece of ass, but I had to do it now, before my lust-weakened resolve had eroded completely and I'd do something I'd surely regret later.
"I thought you said you weren't a prude," Eileen sighed in disappointment. It was obvious she wasn't going to settle for anything less than full penetration. As much as my penis would have loved to comply, I would not allow it.
"I… I think I ought to leave" I said, taking a step back.
"No baby, don't leave now, we've only just got started." Eileen replied, visibly annoyed by my refusal.
"Yeah… well, I'd better go anyway."
Like before, my rejection was not at all to Eileen's liking, and again, she had an ace up her sleeve. In reaction to my relapse into disobedience, she quietly parted her legs a little and relaxed her grasp on my daughter's head. This calculated move allowed Gemma just enough freedom of movement to turn around almost far enough to see me.
"Please Mark, stop fooling around." she urged me, "Who knows when her father shows up again. You don't want to have to explain what you are doing here in Gemmy's bedroom, do you?"
It wasn't hard to extract Eileen's hidden message; she had me by the balls. If I didn't cooperate, the secret of my identity would not last another second.
"No." I sighed and got back on my knees behind my daughter.
"That's better, baby. Don't leave the poor girl hanging."
With mixed feelings I plunged my thumb back inside my baby's waiting pussy and used my finger to tickle her clit. As soon as Gemma started moaning again, Eileen tightened her grip on her head once more and secured it firmly between her thighs.
"I'm sorry baby," she apologized, "I didn't mean to upset you. It's just that… it's obvious we all want the exact same thing, and that's for you to fuck Gemma… I'm trying to help you as much as I can, but it's up to you to make your dreams cum true."
Like before, it was clear that Eileen had chosen these words very carefully. I needed a moment to let them sink in. She was helping MY dream come true? Was she doing this for me, not just to satisfy her own kicks? Thinking back to everything she had done so far, she might be telling the truth.
"But what about… you know… her father?" I asked, still not fully convinced.
"Don't worry, I assure you that nobody will ever know you were here. Whatever happens in this room today will remain a secret between you and me. I was a fool to doubt you, and I hope this proves I will do anything to please you... Do you see what I'm trying to tell you?"
Finally, I was seeing it clearly. Not only had I passed Eileen's test, she had also created a once-in-a-lifetime opportunity for me to have sex with this gorgeous young woman. I must be the luckiest man on earth. Hearing Eileen promise that everything would remain a secret was the final straw. I got into position behind my daughter and resolutely aimed my cock at that delightfully forbidden place.
My heart was pounding in my throat as I watched the blunt head part the hairless lips of Gemma's succulent pussy. The delicate petals of her inner labia cradled and caressed the swollen tip as it moved through her slit. I hadn't even made an attempt to enter her yet, and the sensations were already beyond belief. I swiped it up and down her vulva a couple of times more and teasingly tapped her clit before I let my cock come to a halt over the entrance to her vagina. The pink opening was slightly distended and oozing creamy juices, assuring me that penetration would be effortless, smooth, and highly pleasurable.
I was just about to put that theory to the test and plunge my cock into my daughter's inviting pussy when Eileen stopped me.
