The old couple that lets me eat her pussy

I was 15 when it started. They were an old couple that I knew for years. They said they'd let me into their bed with them when they had sex, but there were rules.
1. I had to eat her pussy even lick her asshole anytime she wanted it.
2. I sometimes would have to jack his cock off and aim it at her pussy (he couldn't always get hard enough to penetrate her but could cum)
3. I could only jack off watching them, suck her tits only. NO FUCKING HER.
I could jack it between her tits, even rub off between her massive buttcheeks. NO FUCKING.

I agreed, they were both fat, she had huge jugs, big thick thighs, and a hairy brown/gray mix of pussy hair. He was fat, had a small, probably 5 inch long, thin cock with hair all over it. She was 51 he was 58.

Naked on the bed with them, I was eating her big, hairy pussy while she was getting wet enough for him to fuck her. She didn't cum from getting fucked by him, but would cum twice while I ate her and got her wet enough. He' would sneak his hand to my butt without her knowing, even massage my balls while he was jacking on his cock ready to fuck her. I'd move and she'd lift her massive legs, giving him free entrance to her pussy. I watched it go in and he jerked wildly, never slowing, just rapid fucking for about 3 minutes then push in and cum inside her. While he fucked her I'd be pleasuring her massive EEE cup titties with my mouth. Then she'd push me down "Do it again, now!" she demanded and I went down on her just fucked pussy. I had never tasted my own cum, and I didn't like his, but her pussy mixed with it wasn't awful. I licked her clean, she came again and it was my turn. For my first time she put lotion between her big tits and I got my 7 incher off, shooting it on her chest and face. She scooped it up and put it in her mouth, giving the last fingerful to me. I didn't want it but she pushed it into my mouth anyway. His hand was on my ass the whole time I was pumping into his wifes tits.

The next time she was alone, called me over to eat her and I did. Then she lubed up her butt crack and rolled onto her stomach. She had a big butt and the cheeks on each side made a nice fuck. I shot all over her back. "Lick it all up baby, don't leave anything, I want you to eat it all". I did it and she kissed me with her tongue in my mouth. "that's my sweet baby " she said. We had more sex with both of them, and I would sometimes get behind him as he was kneeling between her big legs, my cock getting hard against his ass. I'd reach around and jack him and he'd start panting and talking to me "That's it, that's it, keep going, make me shoot all over her fat whore pussy, shoot my cum all over my whore wifes hairy cunt" and with that he's shoot, I'd push into him to get his cockhead at her entrance. Then I would eat her to cumming again, his hand now quite outwardly on my cock, my ass, my nipples. That one time we did all just like that, and she rolled over, he squirted the lotion on her ass and rubbed it all over my cock. He stopped so I wouldn't cum, then instead of rubbing it in her buttcrack, he made her spread her ass and put the tip into her ass. "only the tip, don't fuck her" he insisted. I wanted to move, I wanted to press it into her further, the tip and about an inch after the head was inside her hot, tight asshole, it felt incredible. He was jacking it for me. I felt his cock in the crack of my butt and as I shot off, shallowly inside his wifes ass, I felt heat on my back and butt, he'd cum again, using my butt to get off.

It has continued like that, I'm now 16 it's been a year and a half of this. Sometimes she has this secret she keeps from him, when we're alone and she cums with my mouth, and rolls over for me to fuck her buttcrack instead of between her tits, she reaches back and sticks my cock at her hole. I buttfuck her old hairy woman and cum deep, deep inside her big fat ass. It's heaven. She's gone shopping or out with friends for a few hours, and he has fucked me in the ass. They both say the other doesn't know. I've sucked his cock, he's sucked mine and we've bothed fucked each others ass.

I know it's sick, but I really want to fuck her hairy cunt too. I think I'm gonna change the rules on them. I want the old, fat lady's pussy to fuck. My first pussy.
