Their shared space ignites a spark, and they engage in a heated argument that quickly turns into something more. Tati's eyes wander to her brother's crotch, noticing his growing erection. She tentatively reaches out, stroking him, feeling him harden. He responds, his hands exploring her body, cupping her breasts, and sliding down to her wet, throbbing pussy.
