A lonely man attends his first marriage party after a breakup and feels outclassed by the older, more accomplished guests until cute Minami Kojima and busty Saki Okuda approach him. Drinks at a bar loosen his tongue, and he admits that a previous girlfriend left because his sex drive was too strong. The women take him to a hotel, but their expert handjobs, blowjobs, and titjobs make him cum before intercourse even begins. They keep draining him in a reverse threesome, secretly take turns riding him, then start all over again at dawn before teasingly asking which one he wants to marry.
