The phrase "sissy-joyce" is a combination of two porn video tags. Here's what they mean:
1. Sissy: This term is used in the context of feminization or sissification, which involves a man being humiliated and forced into female clothing, roles, and behaviors. In a porn video tag, it often indicates a scene where the male participant undergoes this kind of treatment or transformation.
2. Joyce: This could refer to a specific person named Joyce who may be involved in the scene, either as a performer or in another capacity. Alternatively, "Joyce" might simply be used as a general descriptor for the type of sissy content being depicted.
So, the tag "sissy-joyce" suggests that the porn video features a male participant who is subjected to humiliation and feminization, possibly involving someone named Joyce or related to her in some way. As always with pornography tags, this should be considered as part of an adult audience's understanding and may not be suitable for all viewers.
