In the darkened living room, Uncle Jack's eyes were fixated on his two young nieces who were giggling and undressing each other. He listened intently as they whispered about wanting to feel something new. His heart raced with anticipation as they crawled onto his lap, their soft skin pressing against his hardened cock. With a delicate hand, he unzipped their mini dresses and slid them off their bodies, revealing their tiny panties. He couldn't believe his luck; they were both barely 18 years old and willingly offering themselves to him. As they straddled him, he guided their small hands to his rock-hard shaft, moaning in approval at their touch. He leaned in and kissed them both passionately, tasting their innocence. With a swift move, he pushed them both onto the couch, spreading their legs wide.
