Sadiville entrusts a specially made Big Bang Vibrator to a middle-aged couple and sends them off to a hot spring resort. Stimulated by the power of the Big Bang Vibrator, they do whatever they want in the inn. They openly perform a blowjob in front of the waitress, squirt in orgasm in the hot spring due to its power, and mercilessly suck the man who begs them not to cum, showing off a performance that would put any slut to shame.
