“I tried to make it as comfortable as I could, but I wanted to make sure your balls had room to hang so the girls can get to them too if they want.”

My head started spinning as my daughter made this last remark. I suddenly realized I was harder that I had been in years and my throbbing cock was now poking straight out in my pants. Lindsay didn’t make any notice of it, so I tried to ignore my excited state and asked her about the straps on the chair.

“I’m not really into S&M stuff,” I said.

“The straps are to help make the girls feel safer. It helps them feel like they are in control and free to explore and experiment at their own speed. If things go like I hope and the girls get comfortable with everything, maybe we can take them off later.”

I was searching my head for some logical argument to make. My grip on morality was failing fast and my daughter could see I was struggling for any reason to resist further. My daughter had planned everything brilliantly, and left me little to work with. I kept asking myself if this was really happening. The details and reality of what she was suggesting were finally beginning to congeal in my head.

“So they won’t know it’s me, and I won’t know which of them is…um, touching me, right?” My resistance was almost gone now.

“Well…” she began. “…that’s where I modified the website’s idea a bit. I made you a special hood you can see out of almost perfectly, but they won’t be able to see you.”

I felt my cock throb against my pants when she said this. I would actually get to watch these young girls use my cock for their own curiosity and pleasure, without them knowing I was really their best friend’s dad. Then a thought occurred to me.

“What if they change their minds or get freaked out?” I asked.

“I told you. I already discussed this with them. They’re really excited, dad. Kristy told me she already masturbated twice this morning thinking about it, and Amy told me she was already soaking wet when she got here.”

That was it. My last barrier of hesitation and decency washed away as I finally nodded to my daughter.

“Ok,” I resigned. “I guess you got all the answers, and I did make you a promise.”

“Yay!” my daughter cheered as she clapped her hands, kissed me right on the lips, and gave me a big hug. I became all too aware of my massive erection pressing against her as she held me. She must have felt it to, because when she let go she looked directly down at my bulge and said “Let’s get that thing some of the attention he deserves.”

Quietly we stepped back inside the house behind the makeshift curtain.

“Time to get naked, daddy!” Lindsay said with enthusiasm. I was about to protest, but then realized at this point it would be kind of dumb. I stripped off my shirt and pants as my daughter stood there watching. I was about to pull my boxers off when one last detail occurred to me.

“Um, you’re not going to be…you know…um, participating,” I asked hesitantly. It was one thing to let her friends fondle me anonymously, but I didn’t think I was ready to let my own daughter touch me like that.

“No dad,” she answered quickly. “I already told the girls I wouldn’t be doing anything since I know who the guy is. I told them it would make things way too awkward.”

“Oh. That makes sense, I guess.”

“Besides, Kristy has already offered to throw a party at her house for me.”

“WHAT!?” I yelled in a whisper.

“I’m just kidding dad. I’m not “participating” here or at any of my friends’ houses.” she laughed.

“Right,” I said, confirming her statement to myself more than anything. And with that, I leaned over and slid my boxers off. Now I was standing completely naked in front of my daughter with a full erection.

“Wow, dad!” Lindsay exclaimed. “Mom’s an idiot for not taking advantage of that on a regular basis.” She was now staring openly at my aching cock. “Well let’s get you strapped in.”

As I sat on the chair, I realized that I had even less surface to actually sit on than I had originally thought. The cut away in the chair not only left room for my balls to hang freely, but also left most of my ass exposed too. My daughter knelt down in front of me and reached out for the Velcro straps. She managed to wrap the front straps around my legs without any problems. However, when she leaned over to get to the back straps, her arm brushed against my cock making it jump.

“Sorry” she said, but from the smile on her face I had my doubts. Then she leaned over for the last strap. She was making an exaggerated show of trying to avoid accidentally touching me with her arm again, but this exposed her chest to my crotch as she bent over for the last strap. As she wrapped the last strap around my arm, I felt her chest come into contact with my member. I might have thought it was an accident, except that she didn’t pull away. I could feel the flimsy material of her shirt against the shaft of my cock.

“Just…having…trouble…with this…last….strap…” Lindsay grunted. It seemed like she was having trouble on purpose, and I could feel the rough lace edging on her bra. If she moved any more I would be touching…

Then it happened. Lindsay got the last strap on with one final stretch, and when she did I felt the bare swell of her breast press roughly against the head of my naked penis. The soft heat of her skin against mine caused my body to react unconsciously, and I thrust up slightly against her soft flesh and groaned.

“Easy there big chief,” my daughter kidded as she stood up. “Why don’t you save that for the girls?”

“Sorry,” I said sheepishly. I didn’t know what else to say.

“No worries,” she replied with a smile. “Well, are you ready?”

“As ready as I can be.”

“You can say that again,” she said looking down at my crotch. “Well, here we go.” And with that, Lindsay placed the hood over my head.

She was correct. It was amazing how clearly I could see through its black material. It was no more restricting than wearing a pair of sunglasses. My chest was pounding as I realized this was really about to happen. There was no turning back now.

“Now remember,” Lindsay whispered. “You have to act like you can’t see who’s touching you. You can’t say any names. You can’t talk to the girls directly – unless it’s to moan or say they’re doing a good job or something. You don’t want them to figure out who you are.”

Then without warning, my daughter reached out, took my hard cock in her hand, gave it a quick squeeze, kissed me on the cheek, and said “I love you, dad. Have fun.” Then she disappeared behind the curtain to rejoin the other girls.

I could hear the other girl’s asking Lindsay if everything was ready. Lindsay assured them everything was going to plan. Their penis had arrived and her dad was gone for the night. She told them the movie had about fifteen minutes left, and then she would unveil their surprise.

The next fifteen minutes seem to take an hour. I could hear indistinct whispers and laughter coming from the other side of the curtain every now and then. The time to myself gave me a chance to really digest what was about to happen, and I began to fantasize about each of the girls.

Lindsay and Kristy were both the same age and had grown up together. At one point along the way though, Kristy was moved up a grade. Kristy had long, straight, light blonde hair that she almost always wore in a ponytail. She was 5’8″ and slightly taller than my daughter. She had the kind of body that Playboy looks for. She was petite in the waist, but had a gorgeously curved ass and large breasts that seemed too big for her thin frame. If they had still been printing the magazine, she would have been a lock for a centerfold. Her green eyes, pouty lips, and the permanent look of mischief on her face made her a constant focus of my fantasies.

Lindsay, my daughter, was about 5’6″ with an athletic body. Her medium length dark blonde hair contrasted her bright blue eyes beautifully. Being a man, I have noticed her tight muscular butt and legs. Her hips weren’t as curvy as Kristy’s, but her butt was hard and protruded nicely when she wore tight jeans and sweatpants. Her breasts were a small C, but looked perfect on her sporty body. I had to learn a very long time ago to get used to the way boys would look my daughter up and down when we were out.

Amy was the cutest thing I had ever seen in my life. Amy was a freshman, just over 5′, and very petite. Her father was white American and her mother was Japanese. Amy, it seemed, got the best of both worlds. Her short, shoulder length black hair and deep brown eyes always drove me nuts. Her petite body was elegant and graceful, even for her age. While she didn’t have the curves the other two girls had, she had just enough to tease something truly sexy under those clothes.

The last girl I knew at the party was Ann. Ann was a freshman too. She had met Amy in school, and through Amy she had met Lindsay and Kristy. Ann was about the same size and build as my daughter, with just a bit more curve. She was also very athletic, but with much larger breast – I guessed DD. She had just a little more curve in her hips, and her butt was also slightly bigger than Lindsay’s. Not that it was flabby by any means! She just always seemed to have a tiny bit more jiggle than Lindsay. Ann had those jet-black eyes that I have always loved, and a seductive innocence in her face that, while it drove me wild, never seemed quite real. Out of all the girls, I was most interested to see how Ann was going to react to my daughter’s experiment.

The only other girl at the party was Elizabeth, and I only knew her name because my daughter had said it to me earlier. The only thing I could say for sure about her was that she had the same black eyes as Ann, and she had a tiny, sexy little butt. I came to this conclusion after realizing Elizabeth must have been the girl I saw through the keyhole earlier. I would have recognized Ann if it had been her.

My mental review of the girls and their bodies was suddenly interrupted by loud hoots and hollering. It sounded like the movie was over and the girls were ready for Lindsay to make her big reveal. My erection went down a little bit with nervousness, realizing I was about to be exposed to these girls. The sounds of all the girls walking across the room told me I was out of time. I could hear the girls giggling as a hand that must have been Lindsay’s reached behind the curtain.
