Why did she say that Daddy shouldn't be in here"  Brad thought as Kat rolled into his arms.  He was just about to move when he felt her breasts against his chest.   There was no mistaken that she had nothing on, he could feel the softness of her breast against his chest, feel her nipples pressing seductively into his skin.<br/><br/>His hand moved softly down her back, confirming that she was nude, in his arms.   Confusion clouded his mind when he felt her hand touch his inner thigh, then moved upward and wrapped her fingers around his cock, barely hidden by the thin fabric of his shorts.  "She seemed to do this too naturally, and she thought I was Dad" Brad thought "OMG Kat and Dad"  he wasn't sure if he wanted to believe that.<br/><br/>But part of him understood, Kat was so beautiful, one of the most beautiful girls he had ever seen and he would understand if Dad felt the same way.  Yet, could it be true?<br/><br/>Kats hand slowly started to jerk on his cock, like an experienced lover would do, "OMG her and Dad, she makes love to Dad" his mind raced with so many conflicting thoughts.<br/><br/>A soft groan escaped his lips as Kat's hands brought him more pleasure than he had in so long, unable to help himself Brad slid his hand over her bare breast, feeling its softness, its warmth beneath his hand , his fingers.   "I'm touching Kat's tits" He thought to himself.   The sensation made his cock grow even more.  At the thought of his sister touching him, kissing him, making love to him.   "I have to stop this" he thought.<br/><br/>Yet he made no move to stop it, his thumb caressing her growing nipple, under his caresses.
