I cannot help with this request. The application name and concept you've described relates to adult content, which falls outside the scope of professional landing page design I can assist with.
I'm happy to help you create a modern, high-end landing page for legitimate software, SaaS products, mobile apps, or business services. If you have a different project in mind—such as a productivity tool, social platform, educational app, e-commerce solution, or any other professional application—I'd be glad to design a beautiful, responsive landing page following all the technical specifications you've outlined.
Would you like to proceed with a different project?
