Forbidden Family Therapy: Bookworm Step Sister Succumbs to Brother's Big Cock POV

The air in the "therapy room" felt thick, charged with unspoken desires. Dani, my step sister, fidgeted in her chair, adjusting her glasses. Her braces glinted under the soft light. She looked so young, so innocent. Too innocent.

"Are you... comfortable, Dani?" I asked, my voice a low rumble. She was wearing a simple top and a short skirt – typical for her, but tonight, under these circumstances, it felt like a blatant invitation. I could see her small tits outlined perfectly. She was always the quiet one, the bookworm, but lately I'd caught her looking at me differently. Maybe she was ready for this.

She nodded, but her eyes darted nervously around the room, avoiding mine. The silence stretched, punctuated only by our ragged breaths. I reached out, my hand gently brushing hers. Her skin was soft, incredibly soft. A faint blush crept up her neck. Latin skin, warm and inviting. I leaned in closer, whispering, "What if I told you there was a different kind of therapy, Dani? A therapy that uses touch, sensation...pleasure?"

Her eyes widened, a mixture of fear and excitement flickering within them. "What... what do you mean?" she whispered back, her voice barely audible.

I moved my hand to her waist, pulling her closer until our bodies were almost touching. I could feel the heat radiating from her, the tremor that ran through her frame. "I mean," I said, my voice husky, "that maybe what you really need is to feel…to experience something real, something intense." I looked her deep into her eyes before grabbing her head with one hand and guiding her mouth towards my big cock. She was hesitant at first, being a virgin and all, but my encouragement soon set her on her way, her mouth and throat getting used to the taste and size of my member. Minutes felt like seconds as she lapped and slurped away.

She moaned softly as I slipped a finger beneath her skirt, gently teasing her tiny entrance. She gasped, her eyes fluttering closed. "Alex..." she breathed, her voice filled with a mixture of pleasure and apprehension.

I knew this was wrong. This was taboo. This was forbidden. But the desire that coursed through me was too strong to resist. I wanted her. All of her. And judging by the look in her eyes, she wanted me too. It was going to be a long night of family therapy – the kind of therapy that would change us both forever. I knew Dani Diaz would love every minute of it.
