Years of regular exercising had rewarded Gemma with an athletic, yet highly feminine figure. She was by no means skinny, but there wasn't a single ounce of fat out of place anywhere on her body. Covered in creamy smooth skin, her heart-shaped little ass was a true work of art. While not as big and full as her friend's, the delightfully firm twin cheeks were exquisitely curved, with a cute pair of dimples near the base of her spine. Separating those tight globes was a deep cleft that harbored a tiny puckered-up hole. Looking at my daughter's behind was a real treat, and I could only dream of what it'd be like to be the lucky bastard who got to fondle those tight round globes, or to grab them firmly while he pounded her hard from behind.
An inch or so below that tight hole was another one of my daughter's hidden gems; her beautiful pussy. Though the lower half of her sex was largely obscured by her fingers rapidly strumming her clit, her arousal was unmistakable. The delicate skin surrounding her slit was slightly flushed, giving it a reddish glow, and the plump outer labia were swollen and lavishly glazed with her rich female nectar. The chubby lips were pressed tightly together, but sometimes her stroking fingers briefly pulled them apart, and when they did, I was offered a glance of the ravishing pink interior of her vulva. It was almost like Gemma's pussy was winking at me, letting me know she didn't mind if I secretly stole a peek.
I don't know how long I was standing there, ogling my naked daughter and her friend. It was a view no father should ever have of his darling little girl, and it was stirring all sorts of new and disturbing feelings inside me. The hypnotizing sight of her swaying hips and dancing fingers had me fully captivated, and I'm sure I could have kept watching her play with herself like that for hours more without ever getting bored.
With much difficulty I managed to tear my eyes away from my daughter's fabulous rear end, so I could swiftly examine the rest of her body. Though it would be challenging to top that delicious ass, I wasn't disappointed. She reminded me strongly of her mother when we started dating, and also of my sisters when they were around her age. Gemma had clearly inherited the best traits of both our families and managed to combine it into something that was simply beyond beautiful.
Though Gemma's kneeling position offered me a fabulous view of her gorgeous ass and pussy, it also hid much of the rest of her body from my sight. Most regrettable was that I could only see barely half of just one mouth-watering little breast. The petite beauty appeared to be just about the right size to perfectly fill my hand, was slightly cone-shaped, and delightfully firm and perky. The sexy mound was topped with a puffy pink nipple that protruded about a quarter of an inch from the creamy white skin, begging to be pinched or sucked.
As I was still imagining what it'd be like to caress that alabaster skin, squeeze those lovely little breasts or suck on their pink tips, my eyes were irresistibly drawn back to her flushed pussy and her busy fingers. The glossy digits were still moving smoothly and nimbly, obviously well-versed in what they were doing. This notion was soon confirmed, when Gemma uttered a deep groan and then arched her back in a series of jerking motions. With a shock I realized that my little girl was cumming right before my eyes. At the peak of her climax, she was plunging two fingers into her gushing vagina and frantically fucked herself with every jerk of her body. Then, as the first series of bucking motions died away, she resumed fingering her clit in a flurry, and almost immediately a second orgasm took hold of her. She started bucking again, her pussy once more pouring its hot juices over her fingers.
Gemma was having one orgasm after another, each just as intense as the first, in an impressive series that endured for over a minute. When she finally came back down to earth, she withdrew her hand from her sex, giving her hypersensitive pleasure button a little rest while she dedicated all her attention to giving her friend an equally earth-shattering climax. With my view no longer obscured by her fingers, I was now directly looking at my daughter's mouth-watering pussy. I was surprised and pleased to see that both her mound and lips were completely void of hair. No fur shrouding the intimate tissues of her sex, nor was there even a trace of unsightly stubble blemishing the smooth skin that surrounded it.
As I had noted earlier, her plump little pussy was tightly closed, but now I saw that tucked between the chubby lips were a tiny clitoral hood and a pair of the smallest inner labia I had ever encountered on a woman. The thin wrinkly folds only barely protruded from the protective outer lips, just enough to show off their bright pink hue to my spying eyes. Had this not been my own teenaged daughter's pussy, I would not have rested until I had my way with that succulent morsel of female flesh.
For a moment I couldn't help feeling that I was being played by fate, forever knowing that the sexiest, most desirable woman on earth was living right here under my roof, and also knowing that I would never get to lay my hands on her. It was a somewhat depressing realization, but I could still content myself with the next best thing: drooling over her from a distance and memorizing every detail of her tight young body so I could secretly fantasize about fucking her brains out while I was having sex with my wife.
When I finally gazed up from my daughter's delectable body, I was presented with the shock of a lifetime: I was looking straight into Eileen's eyes. I froze in panic, half expecting her to scream. I was already having visions of being brutally murdered by a pair of gorgeous naked girls, my body torn limb from limb and never to be found again. But, as it turned out, my fears were completely unfounded. Eileen gave me a wink and a sultry smile, and then lay her finger on her lips, indicating I was given permission to look, as long as I kept quiet. I accepted her invitation and, knowing I was busted anyhow, pushed the door wider open to better watch the erotic show inside.
While my oblivious daughter avidly continued to slurp on her friend's juicy pussy, Eileen never took her eyes off me. More precisely, she was staring hard at my crotch, where my erection was making an unmistakable tent in the robe. I hadn't forgotten her taste for big cocks and slowly moved my hand over the bulge, emphasizing the size of my member as I was trying to entice her. Judging from the look in my former mistress's eyes, she was definitely interested.
"Show me," Eileen mouthed silently, proving my hunch was right.
I untied my robe and lowered my underwear to offer the girl a good look at my swollen cock. My heart was pounding in my chest. Seeing my throbbing, fully erect penis was bound to bring back some memories for Eileen, memories I wouldn't mind re-enacting at another moment. I decided to up the ante a little and slowly started to slide my fist up and down the shaft. As I squeezed my cock, a small gush of pre-cum oozed from the tiny hole at its tip, coating the head and my fingers in the slick stuff.
I could see that my seductive stroking was having the desired effect on Eileen. She was watching me masturbate intently, lustfully licking her lips as if she was imagining sucking me off and gorging herself on the steady stream of precum.
"Take it all off" she mouthed, her eyes burning with lust. There was a fire raging deep inside her and I knew that the only thing that could quench this inferno was a big load of potent male juices, expertly injected deep inside her hankering pussy. It was something she wouldn't be able to obtain from my daughter, but I made sure she knew damn well where she could get as much as she needed.
My heart was pounding in my throat; it seemed that, if I played my cards right, sex with Eileen was all but inevitable. The idea of fucking the pussy my daughter had just been licking was an enormous turn-on, and I only wished the girls had been doing a sixty-nine, so I'd be able to sample Gemma's juices when I kissed Eileen's lips. Ensuring my conquest, I dropped my robe and stepped out of my underwear, proudly and openly stroking my swollen cock in the doorway.
Eileen moistened her lips with her tongue and looked at me with lust burning in her eyes as she beckoned me closer. I shook my head. Although there was nothing I wanted more than to get reacquainted with my former mistress's greasy pussy, there was no way I was going to step into my daughter's bedroom butt naked, not to mention the obscene hardon I was sporting. Eileen would have to wait until we were alone, and then I'd fuck her so hard that she wouldn't be able to walk straight for days.
My refusal wasn't to Eileen's liking, and I should have known that she wouldn't admit defeat that easily. In response to my silent rejection, she made her next move. It was a strange and unexpected one, and I didn't realize her true intentions until it was much too late.
"Hey Mark!" Eileen suddenly called out, while at the same time grabbing a handful of Gemma's hair and pressing her mouth firmly against her sex. "I was hoping you'd receive my message!"
A muffled sound of surprise arose from between Eileen's thighs as my daughter learned that they had company, and then again as she discovered that she was no longer able to freely move her head. Startled, I spun around to see if Eileen's boyfriend was standing behind me, only to discover the hallway was completely deserted. Turning back towards Eileen, I pointed at myself and asked her with my eyes.
She nodded. She was indeed addressing me while she appeared to be talking to her boyfriend. Why on earth would she be doing that?
"I'm glad you could make it here so quickly." Eileen rejoiced, "Although, I bet you didn't expect to see anything like this, did you?"
"Well, no… of course not" I stammered, trying to sound like an uptight boy less than half my age. I could only hope Eileen's meaty thighs muffled and distorted my voice enough to be unrecognizable.
"You're not mad at me, are you? I know you don't want me to fool around with other men, but you never said anything about women. That's why I invited you to come over. You see, Gemmy and I were talking about a little… ménage a trois, and it got me so horny, I simply could not wait for you."
Wait, what? Why was my little girl talking about having threesomes?
"In fact, I was hoping I might be able to convince you to join us" she added.
I nearly choked, was Eileen inviting me to have sex with her, and my own daughter?
"Err… But… I…" I grunted, too baffled to come up with a more articulate response.
Eileen gave me another sultry smile, "It's okay baby, I won't be jealous. In fact, I can think of nothing that would turn me on more than to see you take her from behind while she's eating my pussy."
I know I said that I missed Eileen's lack of inhibitions when it came to sex, but this was definitely going too far.
"You can't mean… me… fucking Gemma?" I gasped.
