A sexless newlywed couple is invited to a matchmaker's house and is invited to swap spouses. The slutty young wife is confused at first, but gets excited when she sees her husband and the other wife having sex, and before she knows it, she is holding the other husband's hard cock and receiving a baptism of throat fucking in the depths of her mouth. After seeing the other wife and her husband embracing and washing each other in the bathroom, the other husband touches her crotch and she involuntarily wets herself. She is hit with a vibrator on the futon and wets a lot. When she starts having sex with the other husband, the other wife and her husband join in, doubling her excitement. While sucking on her husband's hard cock, she is pounded by another man's cock and cums over and over again.
