In a cramped, dimly lit room, a young, slim teen lies on his back, legs spread wide, as an experienced, muscular top kneels between them. The teen's hole, pink and puckered, awaits its first fisting. The top drizzles lube onto his fingers, then onto the teen's eager ass. He teases the rim, feeling it clench and relax, before pushing two, then three fingers inside. The teen winces, but pushes back, hungry for more. The top responds, adding more fingers, scissoring and stretching until his entire hand disappears into the teen's ass. The teen, now impaled, cries out, his cock leaking pre-cum as the top begins to fist him, pulling out and pushing back in, knuckles deep, fucking the teen's ass with his whole hand. The teen's cries turn to moans, then to screams, as he's filled completely, his ass gaping around the fist fucking him.
