The air thick with tension, they struggle to resist their urges, but the heat between them is undeniable. The sister, her heart pounding, tentatively reaches out, her fingers brushing against her brother's thigh, feeling the muscle tense beneath her touch. He responds, his hand finding her waist, pulling her closer, their bodies pressing together as one.
