[Iris art (Toda Hisaya)] Pair Exchange [Full Color]

A married couple agrees to a timed partner exchange with another pair, sending a shy brown-haired wife into the grip of a muscular stranger who spends days wringing screaming, ahegao-faced climaxes out of her while pinning her in a relentless leg lock. Meanwhile her husband takes his turn with the self-assured Yuna, who teases him about how soaking wet and dishonest his wife's protests sound between rounds. When the swap nears its end, he spots fresh bite marks on his wife's nape and realizes with sinking dread that everything she once did with him has been overwritten by a better man.
