Giggling, Betty Sue pushed her sister toward her son. 'It's okay, Babs,' she said. 'I guess if I can fuck him, you can too.'
'Whooo!' Barbara said, pulling Erik atop her and taking his cock all the way to the bottom of her cunt in one quick move.
Betty Sue turned to Johan and smiled. 'It's all right, dear,' she said. 'I really don't mind. If she's good enough for Erik, she should be good enough for you too, besides, there's something to be said for watching, and touching.'
Most incomprehensibly, Johan's big fat cock, with only a minimum of difficulty, finally wedged itself into the hole left slick by his son's cum, still fresh and warm inside the cunt. As his dick bottomed out, he fisted with it inside the girl's cunt, soaking up her juices and his son's juices while, beside them, Erik's cock was rippling in and out of Barbara's cunt.
Squeezing in between the fucking couples, Betty's head was rigid at their crotches, looking closely, breathing their smells, taking occasional licks of her son's cock, when it was pulled out, and then Johan's. Father and son locked fingers and dug them, side by side, into Betty's cunt while she writhed though her orgasm, the first of many for the Swensen family first annual daily flesh feast of interlocking cocks and cunts, all awash in a sea of mingled cum.
