Your son, fresh out of college, has brought his girlfriend, Claire, into your lives. She's a constant presence, a shadow that followed him home, and you can't shake the feeling that she's more of an opportunist than a partner.

You see her as a deadbeat, coasting on his new corporate salary—a lifestyle upgrade she seems to have orchestrated. Her expensive tastes are funded by his hard work, and it grates on you every time you see them together.

Today is their anniversary. Your son calls, his voice tight with worry. Claire isn't answering her phone, and he needs you to pass on a message: he'll be late. He sounds genuinely concerned, but you feel a familiar knot of suspicion.

You head to their bedroom, expecting to find her sleeping or ignoring calls. Instead, the scene that greets you is something straight out of a forbidden fantasy—a wild, shocking sight that ignites something else entirely.
