Sister in Law wanted to give me a glory hole blow job

Note : This story is completely fictional!

My Sister In Law recently told me she wanted to try something she had seen on the internet. I asked her what it was called and she said that it was glory holing. Now if you have never heard of this it’s when a guy stands on one side of a wall with his cock through a hole to the other side and the girl does whatever she can on the other. Needless to say I was all for it. Instead of ruining a wall and then trying to hide it later I suggested I get a refrigerator box and cut a door into it on one side and a hole on the other. This way I could stand inside and stick my cock through and not be able to see outside. She agreed that it was a great idea and said she would let me know when she had one and we’d set up a time to visit. I got a call two weeks later and she said she was all set and that her husband was going to be gone for a week for some training for work and that I should come and “visit”. I got there as soon as I could and she took me into their room and she had the box all set up. She told me to go ahead and get undressed and get in the box and holler to let her know when I was ready. She left the room and I hurriedly removed my clothes and climbed into the box. I yelled out that I was ready and heard her come into the room.

A couple of minutes later her hand came through the hole and she said to put my cock into it. I laid my semi hard wang into her hand and she gently pulled it and my nuts gently through the hole. She started to stroke my cock from the base and slowly pulled up to the head and it wasn’t very long before my cock was standing at full attention. She worked my cock like this for several minutes and then stopped for about twenty seconds. I wondered what was going on and she said she was getting undressed. Cool so now I started to picture her naked outside my box and that made it even better. She once again took my cock into her hand and started to rub it on her chest and nipples. I started to groan and thrust and I’m pretty sure I was at this point starting to leak fluids. I felt a tongue slide up the slit of my cock and then she took just the head into her mouth and started to lick and suck it passionately. Man it felt good and since I couldn't see anything all my senses were directed at what she was doing with my cock. I heard a click and then a buzzing sound and she really started to moan and suck my cock more earnestly. I realized she had put a vibrator into her pussy and was fucking herself with it and I groaned more and started thrusting my cock gently into her mouth.

Her tongue and hands were all over my cock and balls and it felt so good. I heard her start to cum and she briefly let my cock slip out of her mouth as she wailed in her orgasm. I grunted that I was just about to cum myself and I started to thrust and jerk. She took my cock back into her mouth and started to jerk my cock and squeeze my balls more rapidly. That was it I shouted that I was cumming and I started to pump my sperm into her mouth. I shot three globs of jizz into her mouth and then she started to choke and I felt my cock slip out of her mouth I fired off a couple more rounds of baby seed into the air and then she once again swallowed my cock whole and I dumped the rest of my load into her mouth. She slowly licked and sucked the remaining drops of my sperm out of my nuts and off of my shaft and then she let go of my cock and I pulled it back inside the box and exited the rear and came around to examine the damage. What I saw shocked the shit out of me. There sitting next to my SIL was my niece and both her and my SIL’s faces were splattered with gobs of my sperm and they were both licking their lips. Holy shit I had just gotten a blow job from my niece. They both grinned up at me and I looked down at my neice’s pussy and saw a thin crop of blonde fuzz and the vibrator sticking out of her soaked pussy and her Mom’s hand was working it in and out of her pussy.

My SIL’s hand was also soaked and while I watched she helped my niece to cum to another mind blowing orgasm and when she came down my SIL pulled the slick plastic wang out of her daughter’s pussy and slid it into her own. My niece gently took her mom’s hand away from the plastic dick and started to work it in and out of her pussy for her. She also started to rub her mom’s clit which was poking out of her hairy pussy lips and it only took about two minutes for my SIL to start to cum. She let out a wail and her pussy muscles pushed the vibrator out and it was followed by a spray of gooey liquid as she came all over her daughter’s hands. I stood there and watched it all and then suggested we move to the shower to get this mess cleaned up. We all three got into the shower and we got my niece and her mom all cleaned up. While we were doing that I couldn’t take my eyes off of the soft nubile body of my young niece. She had little apple sized titties with bright pink nipples and her tight young pussy was covered with a fine sheen of golden fuzz. Her ass was small enough I could fit both cheeks into my palms and almost cover them up completely. My SIL was watching me admire her daughter’s body and when my cock once again started to grow she asked if I would like to get to know me niece a little better. I said something like better than getting to cum in her mouth? That got us all laughing and my SIL explained that me niece had admitted to giving a few boys hand jobs and had even sucked a few cocks but none to completion and in fact my cum had been the first wad she had ever experienced. They had been talking and had decided that she wanted to loose her virginity to her favorite uncle, me.

sweet, what could I say but let’s get dried off and then get wet again right? We toweled each other off and my SIL took my niece’s hand and led her to the bed. I stood there and watched the contrast between my SIL’s large ass and my niece’s tight little tush and that just made me harder if that was even possible. They both climbed up on the bed and laid back and spread their legs to expose to me their pussies. Now my SIL’s pussy is very dark and hairy and her fat puffy lips bulged out through her bush but her daughter’s pussy was just a thin slit with soft blonde fuzz all over it. I walked over to the bed and looked down at the feast spread out in front of me and decided that I wanted dessert first and the meal after. I took my niece’s little ass into my hands and dove in between her legs and started to gobble at her virgin pussy. Her soft fur ticked my face as I slid my tongue inside of her. Her tight little ass wiggled in my hands as I ate her yummy little pussy. It didn’t take hardly any time at all and she gasped and moaned and her sweet nectar flowed out onto my face.

I pulled my face out of her pussy and looked over at my SIL who was rubbing her clit furiously with her finger so I just dove into her pussy with my whole face and in seconds her quim erupted in a geyser which almost drowned me. My SIL then said she wanted to watch me take her daughter’s cherry so I wiped my face off on the sheet and climbed up to get on top of my niece and she spread her legs our before me. It looked like a little pink flower peeking out of a dewy golden fuzz. My SIL took a hold of my rigid cock and pulled me towards her daughter’s little pussy. She told me to go slow sp as not to hurt her to much. My niece looked a little scared but I assured her that it would be fine. I told her mom to lube me up by taking me into her mouth and I’d use her saliva to help slick up this little tight pussy. I then pulled my dripping with saliva cock out of my SIL’s mouth and pressed the head in between the lips of my young niece’s pussy. My cock head slid in easily and I started to push slowly and I slid in all the way rather easier than I expected, then I remembered the vibrator and figured it had popped her cherry or she had busted it before by herself. I looked into the eyes of my niece and they were wide open as I slid all the way in and my balls rested on her ass cheeks.

I pulled my cock back out until only the head was inside of her and then once again I plunged in to full length and she groaned and her eyes rolled up in her head. Her mom was concerned I was hurting her and she started to protest and then my niece groaned that whatever I did I was not to stop. I grinned and started to pump her pussy like it was her mother’s. After about four minutes of me fucking the hell out of her she once again started to cum and her tight little twat spit my cock out with her orgasm. I picked her up and spun her around into the doggy position and I looked down at her tight little ass with it’s little brown eye winking back at me I stuffed my cock back into her pussy. I was fucking her like a mad man and I started to grunt and groan and her mom warned me that she was not on the pill and that I had to pull out of her before cuming. She had to be joking. There was no way I was going to be able to pull out at the last minute and be any good for me. I told my SIL to get her pussy ready for me as I was going to make her daughter cum one more time and then I was going to pump my seed into her worn out old pussy instead. I pumped my little niece’s pussy for all I was worth and once again she started to wail out in her orgasm. I pulled my cum soaked cock out of her and climbed in between my SIL’s spread legs and I pushed her legs up so they were over her head and I just started to pour the coals to it and in no time I felt the cum boiling up in my nuts.

I grunted that I was about to cum and my SIL screamed, not yet and I held out for as long as I could and when she started to wail I just slammed my cock deep inside of her and yelled to my niece that I was putting her load of sperm into her mom. She had been vigorously rubbing her soaking pussy and when I said I was about to cum she clenched her face up and exploded which sent me over the top and I pumped a gallon of sperm into my SIL’s gaping cunt. I grunted and pumped and groaned and jerked and when I finished cumming my cock slid out and quite a bit of my spunk leaked back out of her pussy. My niece took her fingers and tried to scoop some back into her mom but there just wasn’t any room left and with her manipulating her mom’s pussy that just sent my SIL into another violent orgasm which sprayed a geyser of her spunk and my gisim out onto my niece’s naked body. We all three laid there spent and then my niece looked at me and said that this was the best 18 year old birthday present she could have ever gotten. Holy shit I had forgotten it was her birthday.

We laughed and once again took a shower to get cleaned up. By the time we got out of the shower it was way after 10:00 p.m. so we decided to just spend the night in the same bed and later around 2:00 a.m. I was awakened by my SIL and my niece both sucking my cock and licking my balls. They told me to just lay back and enjoy and after about ten minutes I started to cum again. This time I ejaculated about 6 times but only got semen out in the first two pumps. I had just ran dry but it was one of the most intense orgasms I had ever had and it felt like I was trying to pump my nuts inside out. My SIL who had my cock in her mouth at the time let it slide out and watched it twitch and jerk and the only thing that happened was for a little bit of clear fluid to leak out and run down my shaft. My niece licked that up and I passed out and slept all the way through breakfast. I woke up later but hell that’s a whole nother story all by itself.
