In their cozy living room, Tommy is engrossed in a book when he feels his sister's warm breath against his thigh. He looks up to see her licking her lips, eyes filled with desire. They share a longing glance before he pulls her onto his lap, their bodies entwined. His heart races as she starts to tease him, kissing down his abs while playing with his cock through his shorts. He moans softly, unable to resist her. She finally frees him from his underwear, taking his huge erection in her mouth as he leans back into the couch, lost in the intense pleasure. She bobs her head up and down, sucking and licking every inch of his shaft. Their gasps and moans fill the room, their passion growing stronger with each stroke. As they reach climax, Tommy's sister looks up at him with adoration and whispers his name, her body shaking with pleasure and a sense of boldness they've never experienced before.
