Sleep was intermittent. My nerves kept me on edge all night after cumming in Marie. She is the youngest person in my girlfriend’s family and I may have got her pregnant. That would earn total respect and admiration from Janice and everyone else in the family. Visions of a shotgun wedding entered my mind and except for the fact that I really like Janice, I found that I was not disappointed by the idea of being stuck with Marie.

By the time I finished my shower, Janice had gone downstairs. I met Mary in the hall upstairs. Holding a finger to her lips, she shushed me without making the sound. Her outstretched hand pushed gently on my chest, guiding me back against the wall. Her other hand slipped under my waistband and found my cock. Mary had me erect in seconds. A quick glance around confirmed that the door to Marie’s room was closed. The stairs were just out of view and gave an audible warning if anyone started up.

Mary knelt and pulled my shorts out of the way. My dick was breakfast for her. She sucked me just long enough to make me desperately horny and then stood and went downstairs. Neither of us had even said, “Good morning,” yet.

Downstairs everything appeared to be a typical morning. Ken had gone to work, the girls were still in bed and Mary and Janice were drinking coffee and chatting with the tv on mainly for background noise. I read the news on my phone as I ate toast. A message appeared on my phone: “I’m not wearing any underwear.” It came from Janice. I looked up and got a dirty grin back.

It left me flabbergasted. That kind of behavior was not entirely out of character for Janice. What shocked me was that it was my girlfriend’s sexual attention caused more worry than arousal. There were only four other people in the house. They happen to all be attractive women and my dick has been in all of them. This was absolutely a family of sluts. The irony of that thought amused me. Perhaps the true slut is me. Some people take trips to New York and get a shirt that says ‘I (heart) New York’. Maybe I should get one that says ‘I (heart) sluts’ after this.

A while later, the three of us stood in the kitchen while Mary cleared a few things and Janice poured more coffee. Janice leaned against the counter looking out the window when I stepped up behind her. I had adjusted my cock to be upright even if mostly soft so I could press it into the crack of her butt. I received a smile over her shoulder and she clenched her butt in appreciation of my attention. She finished making drinks and left to use the bathroom.

“Did you just do something with Janice?” Mary inquired nosily.

I got Mary to turn around and I demonstrated what I had just done moments before with Janice. Only by now I was getting an erection. Mary enjoyed risk as much as Ally so I grabbed her hips and started rubbing myself up and down against her butt. Even through our clothes Mary felt great. She pushed into me as I bucked against her. If we had a little more time I could have cum in my pants, but Janice would not take long enough before she returned to the kitchen.

There was vague movement in my peripheral vision which made me snap my head to the left. Ally stood in the doorway staring wide eyed. As soon as I looked she ducked back out of view. I tried to be cool, and slow down casually before letting go of Mary. Softly, I said “I thought I heard someone.” Until I said that, Mary had been trying to keep my hands on her hips.

Back in the lounge Ally was nowhere to be seen. Several minutes passed before she returned and when she did she was dressed to go out. Her mother immediately asked, “What are you dressed like that for, Ally?”

The reason was obvious to me. Ally wanted my dick for herself. The answer she gave was, “I want a guy’s opinion on some of my outfits.” She walked around in front of us and did a turn. Then she asked me directly what I thought.

Ally wore a tight skirt with a multi-colored zigzag pattern going around it in red, orange and earthy tones. Her top was cream and shoes were a similar neutral color. She looked sexy and completely fuckable. The edited version came out, “I like it.” The non-committal response was not what she had hoped to hear. She told me to remember it for comparison and she ran back upstairs.

The next time Ally came down she had a short black dress with lace trim and black heels. I told her it looked classy and when only she was looking my direction I adjusted my cock and gave her a thumbs up. Ally hid most of her smile at my arousal. It was clear that she was pleased by the way she kept looking at my groin before leaving the room.

That was not the end of it. The third outfit was a shiny pink skirt, made of fake leather or PVC or something. It was snug around her hips but loose at the hem a few inches lower. This time a white top with spaghetti straps that showed good cleavage and pink patent heels, again making her legs look great. Her mom was not impressed. “For God’s sake, Ally! How many things are you going to put on?”

“It’s a great skirt, Ally.” I got up and walked to the kitchen. The odds of Ally following me were fairly high. My theory was proved correct. I stood to the side of the doorway to avoid being seen by anyone in the other room and asked Ally to walk across the kitchen. Her pink heels clicked on the floor with every step. She turned and I put a hand up for her to stay. She leaned back against the counter and I pushed my shorts down and jacked off a little while looking at her. For her part, Ally hopped onto the counter and nearly fell backwards into the sink. If the goal was to flash her pussy at me it was successful. Unfortunately, she squealed like a girl, which is okay since she is one, and Mary thought she had hurt herself and quickly came to check on her.

There was no suspicion towards me. I was on the other side of the room, heading back to the lounge. I claimed not to see whatever happened to Ally. I was just glad she recovered enough to get her feet back on the ground and pull her skirt down before her mother made her put on panties. Hurray for girls going commando!

Things settled down for a while after that. I sat on the smaller couch with Janice and Ally joined her mother on the other. Settled down was far from dull. From across the room, Ally made a point of moving in ways that drew my attention to her legs. She never changed out of the pink skirt. Pointing one foot out or simply running a hand down her leg easily caught my eye. On top of that she winked, gave me quirky one sided smiles and licked her lips while glancing at my groin.

About an hour later, Marie came down in a pair of the skimpiest yellow shorts ever made. I was relieved to see that she was not obsessing about potential pregnancy. What she did notice was how Ally was dressed and immediately interrogated her with a mix of sibling intrigue and competitive bitchiness. Ultimately, this resulted in Marie stating that she had something to try out too. Having come down barefoot, she skipped around the couch and gingerly climbed the stairs back up to her bedroom.

Not more than a minute later, the sound of much slower and more careful steps could be heard descending the carpeted stairs. As Marie came into view my first glimpse was from her knees down. She had a pair of translucent mule heels that just slip on and have incredibly tall heels. I could only stare as more of her body moved into view.

Sitting right next to Janice was not the ideal place to readjust my cock, so I let it strain against my shorts and create a slight visible lift. Janice said, “Wow!” and sounded impressed, not at my crotch, but Marie. It was not clear if she admired the shoes or the fact that Marie was walking down the stairs in them. Marie smiled at her aunt appreciatively and walked around the back of our couch before the others could see her fully.

Her mother spoke up first. “When did you get those?”

Before Marie could answer Ally interrupted, “Those are pornstar shoes! Why do you need those?”

“They aren’t pornstar shoes,” Marie insisted and thus the bitching began.

Mary mediated between her daughters. While she scolded Ally for her implications based on the shoes I got the feeling that Mary had a similar impression herself which took effort to conceal from the girls. Marie revealed that she did intend to go out in them but had not done so yet. Her reason for wearing them now was because she needed to practice walking in them. They were seven inches tall with a two inch platform. The top of her foot formed a nearly straight line with her shin which did make her legs look longer and sexy. She did struggle to keep her balance and I heard her ankles pop as she walked back and forth across the length of the room and into the kitchen.

When everyone’s attention was focused on Marie I quickly adjusted myself and was relieved that my dick was finally able to become fully erect without resistance. Avoiding looking at Marie was damn near impossible. It took a long time before I noticed anything above her legs. I enjoyed seeing a few inches of her smooth belly exposed by the half shirt and then I choked on my own saliva.

The skimpy shorts Marie wore were tight fitting. I had no idea if they were lycra, nylon or something else but the fabric was extremely thin and pulled up so tight that there was a visible crease where it was jammed in her pussy. There was only one way it could have happened: Marie spread her pussy and pulled her shorts into it.

Several times I have thought that Marie was a little too skinny. As a red-blooded male it was simply my duty to fuck her when the slut offered herself. However, seeing her like this gave me the strongest desire to fuck that I had felt in weeks. The instability of her balance increased her appeal even more. My cock was raging. I had to get up and go to the kitchen. It did not matter that there was nothing I needed in there.

I stood by the sink staring out the window and squeezing my cock with one hand down my shorts when I heard the click of heels enter the room. Looking over my shoulder, I saw Marie walking towards me. I pushed my shorts down with my free hand and turned to let her see me jack off as I stared at her.

A smile spread across her face. Marie tried to speed up and wobbled. The challenge of walking in her shoes prevented her from walking faster and served to increase my lust in an instant. As she neared me she reached out and I let her take hold of my cock. I pulled her close to whisper in her ear. “I really want to fuck you in those shoes.”

Another set of clicks began. Ally came to join us. This was most likely to prevent her sister getting sexual attention instead of her. Marie blocked any view of my cock but refused to let go so I could cover myself. She whispered back, “Me too,” before Ally was near enough to hear.

Marie turned her head and raised a finger to her lips with a quiet shush to Ally. Ally looked from Marie to me and then saw my cock in her sister’s hand and spoke a soft, “Oh,” as her eyes grew wide. It was the most cooperative moment I have witnessed between them as they each placed a hand on me to stroke my cock together. The addition of a mildly intoxicating scent drifted over me from Ally’s direction. My gaze grew even more lustful as I thought about fucking them both.

The girls stood close together and they would have to remain that way for me to have any chance of hiding my dick if Janice or Mary followed us into the kitchen. Two sexy sisters playing with my cock was a thrill, but I could not stop worrying about getting caught. Even though Mary knew things had happened she could have no idea how much and I had no basis to guess how Janice would react to catching me fucking her nieces.

The potential reactions of Janice were flipping through my mind when Ally squatted down. Ally let go of me and Marie fed my dick to her older sister. My pulse quickened more from panic than pleasure, although Ally did great things with her mouth. Marie stepped aside, giving Ally room to get directly in front of me. All I felt was my dick throbbing inside Ally’s mouth. The only other thing on my mind was watching for any kind of movement through the doorway to the lounge.

Marie would not be a simple bystander. She spread her legs and used her hands to peel her shorts out of her pussy. Covering herself was not the objective. The shorts were pulled to the side and then up tight again, this time out of the way of her pussy. Marie took my left hand and sucked the middle and index fingers. She got me wet and then placed my hand on her pussy.

There was no need to talk. I pushed my two wet fingers into her and was soon working her pussy. Ally shifted herself so she was kneeling instead of squatting which must have been more comfortable. I put my hand behind Marie’s neck and pulled her close for a kiss. I thrust my tongue in her mouth as deep as my fingers reached in her cunt. We wrestled tongues playfully until we were both wet all around our mouths.

Pleasure became more important than fear. I asked them to swap and the response was immediate. Marie chose to squat like Ally did at first, but spread her knees wide and started fingering herself before taking my dick in her mouth. She reached behind me and grabbed my butt too, which I soon learned was because she had trouble keeping her balance like that.

Ally hiked up her skirt and since she also had heels she was able to put one knee and foot up on the counter. I put two fingers of my right hand in her mouth and felt around her tongue to get them wet before stuffing them into her cunt like I did to her sister. Ally initiated a kiss but it was brief and then she guided me down to her breast.

I love feeling the soft flesh of a breast against my face as I suck on a nipple. My hope is to also please the woman and I interpreted erratic breathing from Ally to be some indication of her arousal. The efforts of my fingers in her pussy were clearly a more significant contribution.

My attention wavered when my cock was no longer being sucked. Instinctively, I tried to look. Ally held me firmly to her breast and told me, “Don’t stop.” Since I had no real complaint I did not persist with my attempt to extricate myself from her embrace.

Once more my cock felt a moist warmth. Marie had stood up and backed into me and I welcomed the snug grip of her pussy. I put my hand on her hip and immediately felt her grasp my wrist. She wanted me to reach further around her, but I could not do much while leaning to the side and blindly finger fucking her sister.

It was inconceivable that these two loudmouth sisters were doing all this so quietly that we were not heard in the next room. I did my best to support Marie by pulling against her hip while we slowly fucked to avoid the slapping sound I really wanted to make with her.

By the time Ally eased her grip I was desperate to fuck hard. I asked Ally, “Can we go outside and fuck properly?” A smile answered my question. Ally glanced towards the lounge door, as if it was any good to do that now, and headed to the back door without pulling her skirt down to cover her pussy. I helped Marie straighten up and pulled out of her, whispering our intentions and turning her to follow her sister.

Outside we could be a bit louder since the windows were closed. Their driveway goes along the side of the house to a garage set back behind. Just around the back corner there are no windows on the house. It gave us a reasonably safe spot to hide where the girls could go without taking off their heels. I told Marie that I thought I should fuck Ally next or she might get upset that Marie got more attention.

On the way I grabbed a cushion off one of the patio chairs. I dropped it on the ground and asked Ally, “Can I fuck you upside down?”

“Which hole?” she asked, already placing her hands on the ground.

“Whichever you want?” I answered. My main interest was to see her in that position I was happy to put my dick in either way.

Our desires must have been equally...
