In the dim light of their shared room, siblings Michelle and James find themselves alone and horny. Michelle, wearing only a thin pair of knickers, begins to touch herself, her breath quickening as she imagines James's hands on her body. James, noticing her arousal, joins in, stroking his hard cock through his boxers. They exchange furtive glances, their bodies aching for each other. Michelle's knickers grow damp as she watches her brother's hand move up and down his length. They're both close, their bodies tensing as they hurtle towards climax, when suddenly, their mother's voice echoes from downstairs, forcing them to quickly composed themselves and hide their secret pleasure.
