Stepbrothers wager against their stepsisters for a steamy threesome

Two stepbrothers, both harboring feelings for their respective stepsisters, decided to make a wager. Whoever could get the other stepsister to put out first would win a trip to the mall. The stakes were high, but the reward was worth it. The girls, both 18-year-old cuties with small tits and a naively youthful charm, were eager to please their stepbrothers. They took turns, first giving a sloppy blowjob to one stepbrother, then riding him hard and deep. But the real fun began when they allowed their stepbrothers to take them from behind, their tight asses bouncing with each powerful thrust. The girls moaned and writhed in pleasure, their bodies wracked with ecstasy. The stepbrothers took turns fucking them in various positions, from doggy style to cowgirl, until they were both spent and satisfied. This was a taboo 4 some that pushed the boundaries of their relationship, but it was a risk they were willing to take for the thrill of it all.
