A couple visiting for a private AV shoot. The wife, who wasn't initially keen, starts giving her husband a blowjob for his sake. However, the real purpose of this shoot was for the husband to see his wife being embraced by another man... The husband, unable to get aroused, is offered a stand-in, and the wife agrees under conditions like no kissing or insertion. Will the wife, who keeps being rubbed with the stand-in's foreign penis, allow the insertion that is forbidden...?
