Madi Collins and Aria Carson, bored and ignored by their stepdad, find solace in each other's company and some heavy lifting in the garage gym. Madi, a fit teen with a penchant for tight spandex, can't help but notice Aria's growing bulge in her workout shorts. Aria, a muscular, tattooed stepbrother, catches Madi's eye and decides to tease her a bit, flexing and showing off. The tension builds as they work out together, their bodies glistening with sweat. Madi, unable to resist, drops to her knees and takes Aria's throbbing cock into her mouth, giving it a deep, eager blowjob. Aria, loving the attention, puts Madi in doggystyle and fucks her hard, using her tight pussy for his own pleasure. Afterward, they collapse together, spent and satisfied, their secret taboo tryst complete.
