SW-1057 Ayase Maina, Mei Mizuki

All the wives have huge breasts! Three couples swap partners and have swapping sex in front of their husbands and wives! A young couple invited by a slutty couple is immediately subjected to sexual harassment, with the slutty wife sucking the husband's dick right in front of them. They separate into different rooms and begin swapping sex! The pleasure of peeking and being peeked at is doubled. Their big breasts shake as they are vigorously pounded by dicks other than their husbands'.
