Vacation with non-family members

On a recent holiday, our protagonist found himself in the company of his stepsister and her boyfriend. The atmosphere was charged with the excitement of new adventures, and they decided to make the most of their time together. As the night fell, the atmosphere became more intimate, and the stepsister's boyfriend revealed his true intentions. He had been harboring a deep desire for his step-sister, and now, on this holiday, he had the perfect opportunity to explore their relationship. With the consent of his step-sister, he proceeded to seduce her, his hands exploring every inch of her body. The intensity of their encounter was only heightened by the fact that they were sharing a room with their step-brother, who was blissfully unaware of their tryst. The sight of his step-sister being pleasured by another man only served to arouse him further, and he found himself joining in the act, adding his own touch to their passionate encounter.
