I doubt her boyfriend had her husband’s view of their coupling in mind when he entered her this way, but nonetheless, it’s a great position to physically share a wife between boyfriend and cuckold.

She may only be able to hold onto his hand while her boyfriend is really working that cock into her, but when he slows down or rests inside her, she may have a moment to look into her cuckold’s eyes and taunt him lovingly by telling him how her boyfriend’s swollen state feels inside her.
