Write the following story: After a struggling couple decides to experiment with their sex life, the boyfriend uses a mysterious ray gun on his girlfriend. In an incredibly rapid and life-changing transformation, she is turned into a blow-up doll. Her body grows into comically exaggerated proportions - her breasts only slightly but her ass grows to a size where each cheek is equivalent to the size of her torso. Not only is she sensitive to pleasure, but her mind and body become severely constrained, making it hard for her to think about anything other than sex. Although she retains consciousness and the ability to speak, her communication is limited, while her boyfriend becomes increasingly fixated on her transformed body and takes complete control over her sexual pleasure.

Emphasize the woman’s emotional journey, detailing her horror, and pleasure. Use both internal and external perspectives to detail her sensations. The story should be highly detailed, leaving nothing to the imagination, and should explore every aspect of the transformation in all its horrifying detail.

Focus on the woman’s experience. Use specific words such as tits and ass and vulgar slang. Write as long as possible. Aim to reach the token limit with highly detailed and graphic language.
