She braced her hand on either side of Chris' shoulders and began to move her hips up and down faster, gritting her teeth at the exquisite pleasure she was receiving from the dual fucking, gradually picking up more and more speed.
Chris' hands came up to grab her tits as his own hips began to fuck upwards, driving his cock into her pussy faster and harder. He raised his head as he pushed her tits together and sucked on both her nipples at the same time.
Behind her, her father was gripping her tightly by her tiny waist now starting to fuck into her ass with long hard strokes. She could feel the breath being knocked out of her by his long cock and she was panting as she ground her ass down and around on Chris' cock, and then up and back on her father's. She screamed at the top of her lungs as her body began to go into spasms of orgasmic delight from the two cocks.
She began to jerk her hips up and down, feeling as if she couldn't get enough of their two cocks. Chris was slamming his cock up into her as hard as he could, and with a final groan he arched his hips, driving it all the way in. She felt the head of it expand and then her cunt was flooded with his hot cum.
Her father shoved forward so hard that she fell flat on top of Chris, with his cock still spurting inside of her. It forced the cheeks of her ass even closer together, but even that and the weight of her father on her back, his gigantic cock slamming into her ass, could not stop the explosive climax that suddenly gripped her body. Her head seemed to spin and a thousand rockets went off in her cunt and ass as her dad fucked her rear.
As his cockhead expanded and his cock began to jerk and twitch, Keri thought her insides were going to melt. And when his boiling load of cum shot out of his cock she screamed until her throat was raw, her body jerking spasmodically between the two of them.
Over and over her hips jerked up and down. The muscles of her cunt and her ass clamped down on the two cocks, holding them as they continued to fire load after hot load of cum into her pussy and ass.
She didn't know how long it lasted, but then her head began to clear and she could feel her father slowly pulling his cock out of her ass. She whimpered and tried to hold him in, but to no avail. Once he was out, Chris rolled over gently, leaving his cock inside of her as he rested his own weight on his elbows as he looked down at her and smiled.
"After today, just you and me," she told him, her voice a mere whisper, smiling up at him lovingly.
"Well," he said softly, "how about you, me, my mom and your dad?"
"You know something, almost husband of mine," she told him as she wrapped her arms around him and held him close, "I think I love you very much."
