The brothers' secret sessions escalate as they delve deeper into their forbidden desires. One evening, they decide to take it a step further, the younger brother pushing his older sibling onto the bed, spreading his legs wide. He lubes up the dildo, then his own throbbing cock, before pressing the toy into his brother's ass. As he fucks him with the dildo, he strokes his own cock, the sight of his brother's pleasure pushing him closer to the edge. They switch places, the older brother returning the favor, his brother's moans echoing in the room as they both chase their climax, their bodies slick with sweat and desire.
