You Can't Have Her Without Me

Isiah Maxwell, known as Jordan, and his girlfriend Madi Collins, who goes by Stacy, arrive at the front of a residence. The purpose of their visit is for Jordan to be introduced, for the first time, to Stacy's stepmother, Lauren Phillips, who is called Nancy. Jordan is somewhat apprehensive - he is keen to leave a positive impression.
Stacy, too, is feeling a sense of anxiety, albeit for a completely different reason. She alludes to the existence of a unique 'exam' that her stepmother administers to her potential boyfriends. She hopes Jordan will succeed where her previous suitor failed.
Later during the night, Jordan and Stacy are dining with Nancy. Much to Jordan's astonishment, he finds Nancy subtly caressing his foot with hers beneath the table. Jordan attempts to prevent the situation from escalating, but to no avail - Nancy is relentless and apparently indifferent to Stacy's presence.
Left with no other option, Jordan excuses himself to the restroom, leaving the two ladies by themselves. The unique relationship between Stacy and Nancy is then divulged: they have a pact to share EVERYTHING, including their male companions. Should Stacy not want to violate this pact, she'll need to share Jordan too.
Despite her fondness for Jordan and her fear that this might harm their growing bond, she consents to her stepmother's scheme. Together, Stacy and Jordan successfully persuade Jordan into a ménage à trois, which he accepts after some persuasion. It appears he has passed the 'exam'.
or has he?.
