The siblings' shared secret grows heavier with each stolen moment. Michelle, her pussy dripping with desire, takes her brother's cock into her mouth, tasting the pre-cum that's been leaking since they started this dance of temptation. He groans, his hands tangling in her hair, guiding her head as she sucks him off. Meanwhile, she grinds her hips, rubbing her clit against his thigh, seeking friction. They're lost in their own world, the rest of the house forgotten, until a floorboard creaks under their parents' bedroom door. They freeze, hearts pounding, as reality crashes back in.
