One possible plot could be about a sissy character who befriends a transgender girl (tgirl) and they go on adventures together. The 'large cock' could be metaphorical, like representing the big - heartedness or strong will of the tgirl. For example, they might face challenges in a community that doesn't understand them, but they support each other and grow stronger in the face of adversity.
In a more comical take, the 'large cock' could refer to a large - sized pet cockatoo that the tgirl has. The sissy, who is perhaps a bit of a scaredy - cat, has to overcome their fear of the bird as they become friends with the tgirl. They could have all sorts of misadventures trying to take care of the cockatoo together.
Perhaps it could be a story where the sissy is initially intimidated by the tgirl's confident presence which is symbolized by the 'large cock' in a non - sexual way. As they interact more, they learn from each other. The sissy might learn to be more assertive from the tgirl, and the tgirl might learn some of the sissy's more delicate or sensitive ways of seeing the world.
Set the story in a magical world. The sissy could be a fairy and the tgirl could be a wizard. The 'large cock' could be a magical staff that the wizard has which is large and powerful. They go on a quest together to save their magical land from an evil force. This way, it becomes a story of heroism, friendship and magic that is suitable for the whole family.
If we consider this in a non - adult context, 'big cock' could potentially refer to a large rooster. Maybe it's a story about a large rooster that did something wrong and faced a punishment related to its behavior, like being confined to a small area for pecking at other chickens.
Also, in some nautical terms, 'cock' has been used in the past for certain parts of a ship's equipment. So in that sense, 'large cock' could potentially refer to a relatively large part of that equipment, though these terms are not so commonly used in modern nautical language.
It could potentially refer to a very young and eager bird (cock as in rooster) that is always hungry. But this is just a very speculative interpretation given the odd combination of words.
If we consider 'cock' to mean a rooster in a non - vulgar sense, it could potentially be a story about an ex - girlfriend who has an affinity for roosters, perhaps she likes taking care of them or finds them interesting.
In a more complex fanfiction, the '15 - inch cock' could be a symbol of something. It might represent a character's inner strength or a mysterious force that the characters need to understand and control in order to save their world. The story could revolve around the characters' journey to figure out the true nature and purpose of this object.
A sissy - like character could be in a school play. They are often teased for their gentle and less - than - tough demeanor. But during the rehearsals, they discover a special talent for acting, especially in playing more emotional and nuanced roles. Their classmates who once teased them start to respect them for their acting skills.
If 'tranny' is short for transmission and 'cock' is an old - fashioned term for a tap or valve, it could mean that in a mechanical system, the valve in the transmission is too large for its proper functioning.
Well, it could be about a straight guy who is new to a particular social experiment or game that has the name 'gloryhole' but is in a completely innocent and non - sexual way. Maybe it's a charity event where people put items through a hole in a wall to donate and he's experiencing it for the first time.
A sissy - themed theater could be a theater that focuses on stories of the underdog or the more sensitive characters. The plot could be about a young actor in this theater who is constantly underestimated because of his more delicate nature. But he works hard and manages to land the lead role in a big production. He overcomes the doubts of the other actors and the director through his dedication and unique interpretation of the character, and in the end, he gives a spectacular performance that earns him the respect of everyone in the theater.
