Hidden away in the confines of their shared room, the siblings succumb to their carnal curiosity. Michelle's breath hitches as she watches her brother's cock grow hard, tenting his pajama pants. She tentatively reaches out, her small hand wrapping around his thick shaft, feeling it pulse with life. He groans, his head falling back as she strokes him, her inexperience making her touch tentative yet all the more enticing. As she grows bolder, her hand speeds up, her thumb rubbing the pre-cum from his slit, their shared lust growing with each passing moment.
