When you make someone cum over and over for over 1/2 hour this becomes the face of ecstasy

Rain is on the floor, gone. Whatever's in her now doesn't answer in English. It just moans and spits sounds nobody gets. Isis keeps her locked in place, wrists and ankles lashed tight, a fat ball gag jammed between her teeth. Rain’s body jerks, hips pumping air like it can still fuck something that isn’t there. Every time the vibrator slams back on her clit she screams into the gag, eyes rolling, spit sliding down her chin. Isis fists her hard, knuckles disappearing, wrist slick, and Rain gushes across the mat in sharp, uncontrollable spurts. She thrashes, teeth sinking into rubber, blonde hair plastered to her face. The vibrator never leaves her. Another climax rips through, legs shaking, another wet explosion, another animal howl. Isis doesn’t slow. She just shifts angle, drives deeper, makes her do it again. Rain’s throat is raw, voice cracking. She bucks and sprays and drools, gone, and the machine keeps humming.
