Logan easily gathers up his limp headless body with his dad Seth's strapping arms and carries it to his bed and lays it down on the bead, then pulls off the T-shirt over up and over its skinny arms and vacant neck. From the view on his dad's broad shoulders, Logan sees his teenaged body from a different perspective. He runs his dad's thick, rough fingers against the smooth and supple skin of his chest and caresses the developing muscles of his body's arms, shoulders and abdomen. He then notices his body's reactions, the nipples hardening into erect nipples as well as a growing bulge between its thighs.
Logan leans over and takes his own nipple between his lips and lightly tickles it with his tongue and traces circles around the areola, and his body's chest and shoulders shudder in reflexive pleasure. While he continues to suckle his tit, he puts his dad's hand on the other, softly rolling it between thumb and forefinger, while the other starts stroking the outline of his now-twitching erection and soon feels a growing wet spot at the tip.
Logan's lips then start trailing down his body's chest as his dad's hand deftly pulls down the shorts and underwear to the knees, his teenaged cock pulled along with them until it is released and springs against the crotch in its youthful erection. He sniffs his crotch out of curiosity, half-expecting to be repulsed but is instead further aroused from the aphrodisiacal young man musk.
Logan then fulfills a long-held desire and swallows his teenaged cock into his mouth, slicking the hard shaft with saliva with each plunge and massaging the cockhead against his tongue's taste buds, tasting of the pre-cum oozing from its slit. He then takes a long, slow pull, sucking hard to wrap the teenaged cock in the soft grip of his tongue and cheeks, causing it to spasm and twitch from excitement.
Meanwhile Logan can feel his dad's body's growing arousal, too, its cock feeling huge as it pressed against the fabric of the boxers, then finally springing out between the crotch flaps, swinging heavily with motions of him suck off his own body and drops of its own pre-cum dripping.
In a testosterone-driven frenzy, Logan dives balls-deep down on his pulsing wood, the plunge finally triggering waves of cum from it, flooding his mouth. Spit and cum ooze from his mouth as he winds down with a slowing cadence of shorter and shorter pumps, finally ending when his teenaged cock pops from between his lips, spent. Logan hears deeps breaths coming from his headless body as it recovers and settles down in post-orgasm relaxation.
Logan then stands up his dad's body next to the bed, takes his hand and slathers its palm with cum and spit, then wraps its fingers around Seth's cock. The older cock wasn't as stiff and erect as his, but its girth took up the entire circumference of Logan's hand's grip, which he squeezed for a tighter hand fucking. Logan rocked his dad's hips and butt, thrusting his dad's cock's cockhead and shaft completely in and out of his body's fist until his dad's cock unloaded into it, shooting what felt like an unending stream of dad sperm that landed on and dripped down Logan's body's wrist and arm.
As the waves of his dad's body's orgasm subsided, Logan's head cleared up a little bit as he took in the sight of what he'd done. He gently put down his headless body's arm back next to it, and then headed to the bathroom for some wash cloths and towels to clean up the aftermath.
