knees behind her.
When Steve grabbed her hips and rammed his cock into her tight cunt, it shoved her forward and down on Mark's and she felt it lodge deeply in her throat.
Forgotten was Chris and his mother, Mary still crying out for Chris to fuck her for all he was worth, and gone was her father and Susan. She had promised herself that today would be the last time she fucked the two brothers, and she wanted to make it a good one.
Over and over Steve fucked his cock into her pussy from behind while Mark, who had now gotten to his knees in front of her, held her head still while he fucked his cock in and out of her hot and willing mouth.
'Fuck!' she heard Steve yell as he rammed his cock all the way into her, grinding his hips against her ass as his cock began to unload its torrent of cum into her cunt, triggering her own climax.
She began to grind her hips back against him, begging him silently to fuck her more as his cum filled her pussy to overflowing. She could feel it seeping out to run down the insides of her thighs. Seconds later, Mark grabbed her head and urged his cock as far down her throat as it would go and let his own cum blast out.
Keri tried to moan as her body was wracked with one climax after another, but the mouthful of cock prevented her from doing so. She used the muscles of her cunt to clamp down on the shaft of Steve's cock, trapping him inside her while she sucked on Mark's cock, trying to drain the last drop of cum from his balls.
But Steve finally pulled his cock from her, as did Mark, leaving her collapsed on the floor with her shapely ass sticking up in the air.
'Yesss!' she heard Mary groan and looked over to see Chris braced up on his hands, his cock buried in his mother's cunt as the two of them came.
Mary was bucking her hips, her fingers leaving long red marks down her son's back as she opened her mouth and screamed out her climax, finally trailing off to a whimper as the feelings gradually subsided.
Chris collapsed and rolled off of her, his semi-flaccid cock flopping over against his stomach. Keri took one look at the fluid-smeared cock and crawled towards it. She began to lick it clean, loving the taste of Mary's fuck juices and Chris' cum which coated it. When she had it completely clean, she held it by the base and began to suck it slowly into her mouth. She wanted to make him hard again, as there was one more thing she had in mind for him and his mother. Her actions didn't take long and before she knew it, his cock was rock-hard once again.
She released it from her mouth and turned to Mary, who was busy sucking Steve's cock. She was on her hands and knees, her shapely ass sticking up in the air, her asshole seeming to wink at Keri. She directed Chris' attention to it, gently pulling his cock to guide him to it.
Chris got the idea quickly and knelt behind his mother, easing his cock down along her cunt to coat it with the juices flowing copiously from it. He then raised it up and lined it up with his mother's ass, spreading the cheeks with his thumbs and placing the head of his cock against the opening. At that point, Mary's head jerked up off of Steve's cock and she turned her head to look over her shoulder at her son.
'Chris, what are you doing?' she gasped as he started to ease his cock into her ass.
'I'm gonna fuck your ass, Mother,' he panted, holding her firmly by her hips.
His mother's ass was so hot and tight that it felt to Chris like he was entering a silk-lined tunnel. He gritted his teeth, pulled his cock back a couple of inches and then rammed it forward with all his might.
Mary's joy cry was abruptly cut off by Steven, who had grabbed her head and placed his cock into her mouth and down her throat just as her son fucked his cock all the way home in her ass, the two of them setting up a slow steady stroke at opposite ends of her body.
Keri could hear Mary's moans, but as she listened she heard a definite change in them. No longer were they the moans of apprehension, but of a woman who has gone past the emotional barriers and was enjoying what was happening to her.
With a sudden idea, Keri rolled over on her back and slid beneath Mary's body to where her head was directly under Mary's dark-haired cunt. She raised her head and began to lick around Mary's pussy for a moment before finally forcing her tongue between the swollen lips of her cunt. She sucked out the juices there, letting them coat her tongue, lips and face. When she found Mary's clit and ran her tongue across it she saw and felt Mary's body jerk and twitch in climax.
She was so engrossed in sucking Mary's cunt that it took her a moment to realize that someone was now busy sucking hers. She let her head drop down for just a second to see Mark's head buried between her legs and feel his tongue work its way up inside of her. The feeling was fantastic and she smiled as she went back to work on Mary's cunt.
But Mark was an excellent cunt-licker and before long Keri had to release her hold on Mary to handle what Mark was doing to her. She let him pull her out from beneath Mary where he could throw her legs over his shoulders and really suck her pussy. It didn't take long before she was in the throes of her own climax, bucking her hips up against Mark's mouth and tongue as her hands grabbed his hair to hold his face in place.
But when it was over she realized that Mark's cock was hard as a rock, and as much as she wanted to feel that cock inside of her, she had a better idea. She turned over and got on her hands and knees just as Steve shot his load into Mary's throat. As Steve finally fell back exhausted, Keri put her hands on Chris' shoulders and eased him over to his side, his cock still firmly buried in his mother's ass.
Once the two of them were on their sides, she looked at Mark and grinned. 'Go ahead,' she told him, grabbing his cock and pulling him towards Mary.
Mark quickly lay on his side in front of Mary and lifted her right leg and guided his cock to her cunt, easing it in a little at a time. Mary's eyes flew open wide and she reached for Mark, pulling him towards her and kissing him passionately, her tongue sparring with his as his cock slid easily into her cunt. Once Keri was satisfied that Mary was getting thoroughly ass-fucked by Chris and Mark in her cunt, she turned her attention to her own pleasure-and her father.
She looked around and saw her dad busily sucking Susan's cunt as she lay sprawled on the floor with a cushion from the couch beneath her ass to raise it up. Keri crawled over to them and quickly straddled Susan's face, feeling Susan's hands come up to wrap themselves around her waist as her tongue shot out to lick Keri's cunt from end to end, rubbing across her hard clit and causing her to have an orgasm.
She rode Susan's face, letting the older woman suck her cunt and loving it, but she was waiting for Susan to cum so she could get what she really wanted, and that was her dad and his monster cock all to herself. She didn't have long to wait, as moments later Susan moaned into her pussy as Keri's dad brought her to a shuddering climax with his tongue. As soon as it was over, Keri raised herself from Susan's face, turning around and bending over to kiss the other woman for a moment before finally looking up at her father and the cock that was jutting out from between his legs.
She crawled towards him, her eyes glued to his massive cock, reaching up to grab hold of it with both hands. She rubbed her left cheek along one side of it and then her right cheek along the other side. She lifted it up and bent her head to lick the sensitive underside of it, letting her tongue travel the entire length of the massive shaft slowly.
When she reached the end of it, she stuck out her tongue and began to lick all around the huge head, moaning deeply in her throat, knowing that soon the organ would be buried inside of her.
She opened her mouth, stretching her jaws as wide as she could, and eased the head of his massive cock into her mouth, loving the way the spongy mass filled her mouth so completely. She forced herself to relax as much as she could and sucked on the head, using her tongue to coat it with her saliva.
With a moan of desire she slowly moved her head forward, taking his cock in slowly, inch by gradual inch. She stopped when she was about halfway down his cock, letting the muscles of her throat relax and taking a deep breath. She held it for a moment, letting it out slowly as she began to force her head further and further down.
Just this act, the taking of his entire cock, caused Keri to experience a small orgasm and she could feel the lips of her cunt opening and closing, as if searching for a cock to fill them. With a low moan she began to work her way back towards the head of his cock, using her tongue to lash the shaft of it as she did, hearing her father's words of praise.
His comment filled her with pride, because she knew she could do something for him that not even Susan could do, and that pleased her to no end. She began to move her head faster and faster up and down the length of his cock, fucking her face with it as she raised one hand to cup his huge sac of nuts. She gently squeezed them, feeling for the sign that he was about to cum. When she finally did feel his nuts starting to draw up, signalling the onset of his climax, she reluctantly pulled her head back and let his cock slip from her mouth. She then threw
