This is my first story, please tell me what you think or what you would like to see for the next story.
My sister in law is real and I would love to be dominated by her, her husband really is a is a dick, but the story is fantasy.
I've always had a thing for my wife's younger sister, Mallory. She's gorgeous --she's a smaller girl, 5'4, perky tits, and an ass I would give anything to have sit on my face! I've fantasized about her for years but never acted on it. Until one fateful day when I got caught with her panties.
It was a stupid mistake. I'd snuck into her room while she was out and helped myself to a pair of her black thongs. I was jerking off with them when Mallory walked in on me. I knew I was fucked, but instead of getting angry, she just laughed. "I always knew you had a thing for me." she said. "But this is pretty fucked up, I'm just going to pretend this never happened, it would kill Samantha if she found out."
Little did I know that she definitely didn't forget and her reminding me would come sooner than I thought.
A few years later, Samantha told me Mallory was getting divorced from her dickhead of a husband, James. Samantha invited her and her new boyfriend over for dinner, but Tom was running late and would be there shortly. I found myself tongue-tied and nervous being around Mallory, like a teenager with his first crush.
After dinner, Samantha went to bed with a bad headache, leaving me alone with Mallory in the kitchen. She looked at me with a sly smile. "So, remember how you were stroking your dick with my panties, Ted?" she said, glaring over at me.
My heart stopped. "I thought we agreed that never happened?" I stammered.
She laughed. "Please. You were stroking your dick with my dirty panties thinking about me, you think I could forget that?"
I gulped. "What do you want, Mallory?"
She leaned in close, her breath hot on my ear. "I want you to be my little slave. You will do whatever I say, whenever I say it. And if you don't." She trailed off, leaving the threat hanging in the air.
I knew I was in deep shit. But I also knew I couldn't say no to her. "Okay," I whispered. "I'll do whatever you want."
Mallory grinned. "Good boy. Now, let me tell you more about my new boyfriend, Tom."
Tom was a monster of a man -- 6'5″ with arms like tree trunks and a large imposing chest. He was also insatiable, with a sex drive that left Mallory exhausted, she couldn't keep up with his needs. That's where she planned to put me to use.
"You're going to help me out with Tom." Mallory said, "His dick is too big for me to suck, and I can't stand the taste of cum, and he can cum ALOT! If he doesn't get off frequently, he starts to become an asshole, he is usually a really great guy and I like him, so you're going to suck his dick for me instead."
I looked at her "What do you mean it's too big and he cums ALOT?"
She cocked her head, "Well, it's the size of my forearm." as she held her arm up.
I know I said she is a smaller girl, but the size of her forearm?
Mallory continued, "And when he cums, he can cover my whole chest and stomach and it's so thick, it is hard to clean up."
I balked at the idea, I was going to say no, there is no way I can suck his dick or deal with his cum. But one look from Mallory reminded me of what was at stake. "Fine." I said, "When do we start?"
Mallory grinned. "Right now. He's waiting for us. I talked to him to make sure he would be ok with a guy, specifically you, sucking his dick since I can't, I told him you loved sucking big dicks, but Samantha doesn't know, and you always hid it from her. I found out because one of my coworkers saw your ad looking for a nice big cock to suck on frequently. I didn't want him to know about you jacking off with my dirty panties, so I used you being a secret cock sucker as the reason. He said he didn't care as long as he was getting his cock sucked, and since you are such a faggot for cock, he is going to treat you like one. But don't worry, I will even help you the first time."
Tom was in the bedroom already by the bed when we arrived, his huge cock already hard and throbbing, it was fucking huge, they never said its actual size but I guessed it had to be over 14" and so thick, it really was like Mallory's arm sticking out from between his legs, there is no way anybody has a dick that big, let alone could suck that thing, and he had two massive balls hanging down.
"About time you got here," he said, beckoning me over. "Get on your knees, cocksucker, I've been looking forward to feeding you my cock since I got here."
I hesitated, but Mallory gave me a sharp look "It's ok Ted, he already knows you love sucking big dicks, don't be shy."
I walked over in front of Tom waiting for them to tell me this was a prank or something. My heart was pounding in my chest.
"I said, Get on your knees cock sucker". Tom said sternly.
Tom stared into my eyes as I got down on my knees. His cock pointing right at me.
"Oh I can't wait to see him fuck your throat Ted, oh did I mention he only cums while being deep throated!" Mallory said, "He can also be a little rough, hope you are ready!"
"Open your mouth faggot," Tom growled. I did as I was told, and he shoved his massive cock into my mouth hard in a forceful motion, hitting the back of my throat making me gag. He didn't pull back any, just kept pushing forward, choking and stretching my throat out painfully "Mallory said you love deep throating big cocks, so you better get my cock all the way down your throat you fucking cock slut" Tom said.
Mallory came closer and whispered in my ear "You better swallow all of his cock, he can be mean if he doesn't get his way."
