Sam's dad had a bigger package

Looking on, the girls thought they might use Sam's dad, Orion, to add to the fun by making him watch, only to see his cock come out of his shorts because of how big and girthy it was. They looked at each other for a moment, but then they turned to Orion, crawling over to him as they took his pants off, admiring and worshipping how fucking BIG it was. Their pussies were wet like never before, and even Perdita's couldn't help it as she tried to bounce off Sam's dick to compete, making him cum 7 times in a minute so he'd pass out and she could join her daughters.

That disgust Orion thought he felt was immediately gone, replaced with a minuscule amount of shame and a feeling of dominance over his son as he lost control of his reasoning while fucking these women over Sam, using his body as a sex tool and mattress.

Despite the weirdness of the situation, Orion couldn't get out of this trance, enjoying his sense of superiority over Sam by playing various games:

• Orion and Sam compared dicks, which the women judged as they gave Orion overwhelming applause, and mocked Sam, making him cum from a simple touch and a blow of air. They then repeated these comparisons in a myriad of ways, like by sticking their dicks in the same pussy after the other. The first time, Orion went first, making the women fail to feel Sam at all, questioning if he was really even in. During the second match, Sam went first, allowing the women to feel him, but not by much, leaving Sam defeated as they screamed in pleasure when Orion went in.
• In another game, Orion and Sam had the women taste their cum while blindfolded, causing them to spit out Sam's cum, saying how it was salty and nasty, only for them to eat Orion's cum, acting as if it were the best thing they'd ever had.

By the end, Orion was so drunk with power that he asked the girls if they were willing to kick Sam in the balls to get his cum all over their chest, fill up their pussies, and leave a hot look as they showed off the cum in their mouths before swallowing the massive load in one gulp. They were so full of lust and admiration for his manliness that they each kicked his balls and said one thing or another about how pathetic he was as a male, or they just spat on him. As a reward, they got exactly what they were promised, causing them to lick their mother/daughter/sisters' pussies, tits, or mouths, engaging in all forms of yuri as they pushed his cum deeper.

To finish off the night, Orion came on their food as they ate it, hearing their cheers and praise, with each of them giving him a thank-you blowjob.
