I woke up just before eight am, I got out of bed and looked at the weather outside, it was bright and warm, I put shorts and a t-shirt on, brushed my teeth and had a wash.
Went downstairs where dad was sat at the table drink a coffee.
"Morning sunshine, did you sleep well?" he asked.
"Morning dad, yeah not bad, a few dreams that woke me up once or twice."
"Wet dreams knowing you son." He laughed.
My mind raced back over the images I had witnessed yesterday and last night in them videos, I felt my cock twitch in my shorts, I moved to the kitchen quickly before dad noticed.
I made myself a cup of tea and joined him at the table.
"Any plans for today Tim? Meant to be raining later." He said.
"If it rains I will do some more studying dad, if it doesn't I will go see a few friends I think."
"Mutual wanking over porn I bet," He chuckled looking at me, "bet you even wank each other off."
"Dad, we don't do that." But I know you do, I thought.
"No harm in it if you did Son, all sex is pleasurable, I've even dabbled with boys myself, especially when I was in the navy with uncle Tom." He said smiling.
Little did he know that I already know about his bisexual side, but I did not know it was from his navy days.
"What you doing today then dad?" I tried changing the subject.
"Your nan and grandad have a few chores that want seeing to." He said slugging his coffee.
I bet sex is involved, I smiled.
"What you smiling at?" he said.
I quickly replied with, "the thought of you doing chores for your mom and dad still."
He laughed, "Yeah I see where you are coming from."
I finished my tea and washed my cup up, then headed for my room, Jess was coming out of her room.
"Morning bro."
"Morning sis."
"Did you finish that story when I left?" she whispered.
"Nah, I went to sleep."
"Boring, I was hoping you would tell me what happened, oh well guess we can read it together again sometime." She winked and licked her lips.
"Yeah I guess."
"Well, I am off out now, meeting the girls for a shopping trip." She said and went downstairs.
I tidied up my room, put my laundry in the wash basket and went out.
None of my friends were home, so I walked around a bit, when I realised I was by my nans house, dads car was parked on the drive.
I sneaked around the house looking in windows, I must have looked like I was casing the place for a robbery, when I got to the dining room window I saw dad, nan, grandad sitting round the table chatting, I felt a little disappointed as I was hoping to find them up to no good, when I saw Jess Walk in wearing a school uniform complete with knee high white socks, black flat sandals, hair in pigtails, she was followed by uncle Tom in a doctors outfit.
"Everyone is ready." he said to the others.
Everyone followed uncle Tom out the room, I moved to the next window, when I saw them go down the stairs to the basement, I quickly went to the basement window, I could only just see inside from one corner.
I could see twelve elderly men, all naked and all wrinkly, they were stroking their cocks of various sizes, ages at a guess would range from eighty to mid-nineties, I did not think a cock would function at that age or would even have the urge but appears I was wrong.
My Family walked in the room, led by Uncle Tom, nan and grandad were holding cameras, nan a video camera and grandad a normal camera, dad was holding a box but I could not see what was inside it.
Jess sat herself on a sofa, lifted her skirt and began stroking herself over the top of her white panties, the men all cheered, my sister was quite the exhibitionist and she knew she was turning these guys on, and me for that matter, I was already rubbing my swelling prick.
Jess played with herself for a good five minutes with nan filming and grandad taking pictures, she had pulled her panties to one side showing her bald smooth pussy that was glistening along her slit.
Uncle Tom moved behind her, he was now wearing a mask over his eyes like before in the videos, he started playing with her pert breasts, undoing her blouse as he did so, showing off her pale pink bra to the guys.
The men were getting quite excited and most of them sporting hard-ons in their hands as they stroked themselves, dad started handing out mask's from the box to anyone that wanted one, not all of them did.
Jess stood up turned around and bent over, taking Uncle Tom's cock in her mouth, again the old boys cheered and clapped, uncle Tom leaned forward and raised the hem of her skirt up over her back, her round buttocks covered by the white panty material, showing a damp patch between her legs.
I had released my own cock now and holding the thickness in my hand, pre-cum leaking from the tip. One of the old men moved forward and was rubbing Jess's ass cheeks, his cock dribbling pre-cum over the floor, it was about seven inches long and thin.
Jess wiggled her bottom for him as he got more excited, he started to rub his cock up and down her panties when he suddenly sent a jet of spunk into the air landing on the back of her skirt, the rest over her pants leaving them wet and sticky, he backed away, granddad moved in and took close up pictures of the mess.
Another guy stood to the side of Jess and he too rubbed her butt cheeks, but he also stroked her ass crack, running his finger over the gooey mess, he even put some of it in his mouth sucking his finger, he was joined by another man standing to her other side, they both held a butt cheek each, kneading them and parting them.
They both jerked off over her panties, which now looked a real mess, they moved away and again grandad took close ups, the next guy stood behind Jess and lowered her pant to her knees, he knelt down and started licking her all over her ass and crack, Jess wiggled with each touch. The man stood up and jerked his small cock until he cum over her bum, it ran down her crack and Jess reached back and scooped some up, looking at all the men she took her fingers in her mouth sucking them clean, to a huge cheer. She then returned to sucking uncle.
The next guy also knelt behind my sister, placing his hands on either side of her bottom. He licked up what was left of the sperm deposited by the last man. He must have then been licking her pussy or bum hole because she wriggled even more.
He placed his cock along her crack and simulated fucking her, then he held his cock pointing at the top of her crack as his cum spluttered from his willy, this time before grandad could take pictures the next was already moving in and quickly to his knees he dropped and began licking up the cum that was running down Jess's crack and over her anus.
He pulled his face back and began to rub a finger over Jess's holes, he pushed one inside her pussy, took it out and sucked it, then did it again, several times infact, he then got up and re-joined the others, he did not cum and I thought that strange.
I felt a hand reach between my legs, I almost collapsed with shock, it was my mom holding my balls, she whispered, "Fancy finding you here? I knew they would be doing something today so came to see, did not expect to find you, and you are masturbating naughty boy, thought you went to your friends."
"No one was home," I stammered, "I just found myself here and looked to see what was going on."
"And what have you seen to get you so excited?" she asked.
I moved to the side so she could look past me, as she was looking she took my cock in her hand and pulled back my foreskin, then began pumping my dick.
"Ooh another group session, has anyone fucked our Jess yet? I see she is doing the school girl thing again." Mom chuckled.
"No-one yet, but they have been touching, licking and a few have cum over her bum." I replied, strangely feeling quite calm in the situation.
We both watched as four more men took turns touching Jess in different ways, the last one removed her panties all together and wanked off into them, then lay them on the small of her back.
The next one that approached Jess was my dad, he had a mask on now too, he put two fingers inside his daughters pussy while licking her ass crack up and down, then he picked up the panties and began sucking on them.
"You father loves the taste of semen; he reckons he used to suck off half the ships crew when he was in the navy." Mom laughed.
I could not believe how relaxed she was about it all. He put the pants around his cock and jerked off into them, putting them back where he got them from after he cum.
"Would you like to fuck mommy while we watch? You can take me from behind, another lesson for you." She chuckled and moved in-front of me, she pulled her skirt up around her waist and pulled her knickers down and they fell around her ankles, she slipped one foot out of them. She leaned forward and reached back guiding my cock to her already wet pussy, I pushed forward and the head of my penis slipped passed her hanging fanny lips, excitement got the better of me and I rammed in to her.
"Gentle son, enjoy the feeling as you move inside me, and then I can enjoy it as much as you baby, take it back out and try again, there is a time for more forceful heavy sex but this is not one of them, ok?"
"Sorry mom." I pulled my cock out and again guided the tip until it passed her fanny lips, then paused for a second, then pushed about the next inch of my eight-inch cock inside her, as I did this each time until I was all the way in, mom squeezed her pussy muscles around my shaft.
Once I was balls deep I just held there and looked back inside the window.
I could not see uncle anymore and guess he had cum, and old guy sat on the sofa by Jess and she straddled his lap, she placed his cock at the entrance to her pussy and lowered herself down, the man took her breast's in his hands and started playing with them, another man stood behind Jess and slowly pushed his cock inside my sisters ass hole.
"Wow, look what Jess can manage now, I've never seen her take two guys at once in this way before." Mom panted sounding proud of her daughter acting like a slut.
"I will let you try anal soon, you will love it, I love receiving it, especially from a big cock like yours Son, you are about the same size as your dad." She almost purred as she pushed back against me.
I started to make slow movements in and out, holding mom by the hips, her bum wobbled each time I went in, I looked down and could see her puckered bum hole and was quite looking forward to finding out how it felt.
Looking back at Jess, the guy in her ass pulled out and cum over her back, then the guy she was riding thrust up, squeezed her titties and shouted he was about to cum, it looked like he cum inside her.
Grandad and nan moved in with their cameras for close ups, Jess climbed off the man, who was replaced by another, this guy was hard, and his cock about average, he looked really hairy and his balls sagged low, Jess again straddled him and lowered herself on his cock, her ass was filled by another guy, he had quite a big willy, about the size of mine or maybe bigger, he was humping my sister like a machine, nothing slow and gentle about his thrusting.
"Look at him go son, that is how you pound an ass or pussy when it is right." Mom panted.
Her pussy was so wet, I was gliding in and out easily, and when I looked down my cock was shiny with her juices. Jess was making loud animal noises as she was being screwed, another man knelt on the sofa next to Jess, he reached back and spread his bum cheeks, I saw uncle step up behind him and push his cock inside the man's arse.
