My stepsister can be quite immature and demanding at times. Her constant complaints over trivial matters were particularly grating that day. Her clumsiness added to the tension when she managed to soak her shirt with water in the kitchen.

Standing there with her top completely drenched, she was visibly frustrated. Under normal circumstances, I would have dismissed her, but this time was different. With no bra beneath the wet fabric, the outline of her body was clearly visible. Since her nails were still wet, she insisted I help remove her shirt.

Complying, I pulled the soaked garment off. The sight of her, now partially undressed, stirred an unexpected and intense reaction in me. Her pants were wet as well, and almost without thinking, I found myself helping her out of the rest of her clothes, until she stood completely unclothed before me. I was captivated by her form, and my own physical response was immediate and impossible to hide.

"You seem very pleased with the view," she remarked, noticing my state. She then knelt, helping me out of my pants. A mischievous look crossed her face as she saw my arousal, clearly excited by our mutual nudity in such an ordinary setting. The situation felt transgressive, a blurring of lines we weren't supposed to cross.

She took me into her mouth with eager enthusiasm, her technique confident and intense. The sensation was overwhelming and brought me to a climax quickly. She continued until I was finished, then cleaned me meticulously. The image of her afterwards left me deeply aroused.

Later, in her room, we resumed. She removed her underwear and we moved to the bed. Positioning herself above me, she guided me inside her. The feeling was incredible-warm, tight, and deeply intimate. I watched, enthralled, as she moved.

We changed positions, and I took her from behind, her sounds of pleasure filling the room. As my own climax approached, I withdrew, finishing externally. She simply reached for a towel, wiping her face with a casualness that contrasted sharply with the intensity of what we had just shared.
