In a quiet, secluded house, a gay math nerd finds solace in his stepbrother's company, and soon, his cock. The two, bound by taboo, spend hours lost in each other's embrace, the nerd hungrily devouring his brother's massive, uncut cock, slurping and gagging, leaving it glistening and wet. The brother, hard and eager, fucks his stepbrother's face, raw and unprotected, leaving him gasping for air.
