Mark really did not much care for his daughter in law. He never understood why his son had married Abby as she was loud and obnoxious. But, what he really did not like about her was she wasn't very educated so it was hard to carry on an intelligent conversation with her.
He had come to the conclusion that the only reason Abby was in the family was her looks; she was damn hot. It seemed such a waste to put such a sexy body on this shit for brains woman. Abby had gorgeous long brown hair and blue eyes standing about five and a half feet tall weighing a modest 145 pounds. To some folks 145 pounds might be heavy for that height but the packaging was perfect as she had a slender waist but a large round plump ass and wonderful D cup titties.
To make matters worse his son, Matt, and Abby had to move back in with the family having fallen on rough times. Even with his own sexy wife, Sue, around Mark finds himself sneaking peeks at Abby. How could he help it seeing her in her swimsuit and nighties? Increasingly he found himself jacking off thinking about fucking her. It was driving him nuts to the point of plotting ways of getting into her pants or at least copping a feel of her boobs or ass.
Then, about three months after moving in Matt and Abby tell Mark and Sue that Abby is pregnant. Everyone is excited on one level but the soon to be grandparents know it means that Matt and Abby will be staying even longer. Mark resigns himself to this new reality. Mark was glad that he hadn't tried anything with Abby as it was obvious she wasn't using birth control and he might have gotten her pregnant himself.
It took a couple of days but he realized that since she was already pregnant he couldn't get her that way. Over the next few days his lustful thoughts over Abby increased to a fever pitch; he had to have her whether she wanted him or not. It didn't help that the best sex of his marriage had been when his wife was pregnant as he found pregnant woman twice as sexy during and right after their pregnancy.
Now as Abby walked around the house she had gained just enough weight that her clothes were fitting tighter showing off all of her sexiest parts even more than before. Her jeans divided the twin globes of her ass while holding them up tight and firmly and her boobs were nearly spilling out of most of her blouses.
Then one night both Sue and Matt were at work leaving Mark alone with his pregnant daughter in law. Joining her in the living room he sat on the couch and let her finish watching some silly show. When it was over he grabbed the remote and turned off the TV and said, "Abby, I think it is time we got to know each other better."
"Dad, I think we know each other real good; we live in the same house," she said innocently. Mark felt the bulge in his shorts grow to full erection. He knew this would be his best chance; it was now or never.
"What I mean Abby is that you are the sexiest girl I know. You have absolutely massive tits and sexy long legs. And as for your ass any guy would love to bury his head between those two pillows of yours." He watched as she shifted uneasily in her chair.
"Dad, I don't think you should talk to me like that."
"Why not, it is all true. Abby you have a body that doesn't stop. There isn't a man I know who wouldn't love to fuck you."
She was now squirming in her chair trying to figure him out. Panicking she responding, "You are my father in law; you're not supposed to tell me things like that I am sexy."
"You mean I can't tell a sexy bitch like you that she makes me get a hard on every time I see her and that I fantasize about fucking her?"
Abby's face was now blushing as she replied, "No, 'cause I married your son. You really think about me that way, that is weird."
Mark was tired of talking so fired his big shot, "Not any weirder than telling you to get over here and kiss me and let me take off all of your clothes."
"Hell no, dad. I can't do that!"
"The hell you can't!" He walked the three steps to her chair and yanked her up by the wrist dragging the startled girl to the couch. He shoved her down on the cushion and quickly sat down beside her. He had several things on his side not the least of which is that he knew she was really into sex as she and his son had been fucking probably eight or nine times a week just from what he had over heard.
It seemed like there was always sexual teasing between them. But, since Matt had found out she was pregnant he had barely touched her. He was afraid he might hurt the baby. Mark knew that either Matt would realize how stupid he was being or lust would get the best of him. Mark needed to get in her panties while she was likely sexually frustrated at Matt's inattention.
He also knew she was rather gullible and probably believe that he would black mail her. So, Mark roughly grabbed her face and tried to kiss the girl. She flung her head away crying out, "No, dad."
"Abby, I know Matt hasn't fucked you in a couple of weeks and you really need a good hard fucking. Besides, if you don't fuck me right here and right now I will tell Matt that you seduced your own father in law." Of course, he would never hurt his son that way but hoped it would accomplish his mission.
"You fucking son of a bitch, how could you do that. Fuck, I don't know what to do." A couple of tears formed at the edges of her eyes. Her father in law was right she was hornier than she could ever remember and Mark wasn't bad looking. She knew Matt would kill her if he thought Matt was doing it with her.
"What you can do fuck me you god damn slut." He could her body slump in surrender as her looked back at him saying nothing. He grabbed her face once again and kissed her. She barely kissed him back.
"Ok dad, I'll let you do it but just this one time." She felt his powerful hand come to rest on her boob causing a tingle in her pussy.
"Abby you will not decide that. I will fuck you whenever the mood strikes me, understand." She shook her head in the affirmative as she felt her body giving to him. He kissed her again and this time her tongue seemed to have a mind of it's own as it danced merrily with his. His fingers feverishly unbuttoned her blouse revealing her black lace bra. He slung her blouse across the room.
Then standing up in front of her he threw off his own shirt before unfastening his belt and pushing down his trousers to his knees. Abby couldn't help but admire his seven inch weapon but still wasn't ready to cheat on her husband even though she absolutely loved sucking cock. She knew what he wanted but just sat there staring at his erection.
"Suck it now take it into that big mouth of yours," he ordered then grabbing a hunk of her hair he forced her face to his crotch. When his dick hit her cheeks she kept resisting but she knew he wouldn't let her go until she did what he wanted. Reluctantly but excited she gave in and turned and licked the head of his hardness. With his free hand Mark reached down and cupped one of her massive jug; squeezing it firmly.
IF she had to endure sucking his cock she might as well try and enjoy it so, she twirled her tongue all around the head. Then she popped its soft spongy head into her mouth thoroughly bathing it before slowly sucking the entire length into her mouth. Mark began moaning softly as Abby's mouth began to move up and down his pecker. Soon, he knew she was into it as her hands were now cupping his ass so he let go of her hair and reached behind her back and unclasped her bra letting it fall from her shoulders.
Her bobbing head was in the way so he couldn't really get a good look at her tits. But, now that the material was out of the way he could appreciate just how big her boobs were. It appeared to him that they had grown since she had become pregnant. Eagerly she was mouth fucking him while his zeal increased with her breasts.
Mark was in heaven and couldn't understand why his son didn't at least let Abby suck his cock as her technique was masterful. She created a wonderful vacuum as her cheeks collapsed inward while she worked her tongue all over his shaft. He had one hand on her shoulder holding himself upright while the other moved from tit to tit exploring them.
Tension was building in his loins and suddenly he let loose a gusher into her throat. Feverishly Abby swallowed all of his seed down as Mark pulled out not wanting to be sucked limp. Licking her lips and making no effort to cover her nude breasts Abby sat back on the couch asking, "So dad, does that satisfy you?"
Staring at her chest Mark was drooling as he had never seen a more perfect pair of tits in person. Even though she was leaning back her firm orbs were still standing straight out from her ribs with her tiny little nipples pointing right at his eyes. Pulling up his undies and pants, giving Abby a glimmer of hope that this would be all he demanded, he smiled lustfully and responded, "Fuck no, now get your big ass in my bed. I ain't gonna fuck you here on the sofa like trash; we have only just begun."
There was no point in fighting her father in law as he was bigger and stronger than her and besides he might tell her husband. There was the simple fact that her pussy was absolutely aching for cock meat, any cock meat. Slowly she stood up and walked past him whispering, "I don't fucking believe you are doing this to me."
