Her husband calls him a con man and remains wary, but his gentle manner and thoughtfulness win Akane over.

Insisting it is not cheating if he puts in only three centimeters, he presses a cock much larger than her husband's against her pussy. Once she allows the tip inside, their unexpected compatibility sends her into orgasm after orgasm.
