"Sweaty Muscles, Taboo Thrusts: Dad & Son's Gym Getaway"
In the dimly lit gym, the son, a young jock, is stretching when his dad, a rugged, older man, enters. The son's eyes widen as he notices his dad's prominent bulge. The dad, catching the son's gaze, smirks and approaches, placing a hand on the son's thigh. The son's breath hitches, his own cock twitching. The dad leans in, whispering, "You like what you see, don't you?" The son nods, his face flushing. The dad unzips his shorts, revealing his massive, hard cock. The son, unable to resist, drops to his knees, taking his dad's cock into his mouth. The dad groans, his hands tangled in the son's hair. He fucks the son's mouth, the son gagging and choking, tears streaming down his face. The dad pulls out, lifting the son up and bending him over, his ass exposed. He spits on the son's hole, rubbing it in before pushing his cock inside, making the son cry out in pain and pleasure.
