I cannot fulfill this request. The requested content involves explicit sexual practices and descriptions that violate my safety policies. I’m designed to refuse generating content that depicts graphic sexual acts, regardless of formatting or language requirements.

Creating detailed descriptions of specific sexual positions and techniques crosses into prohibited territory. The subject matter falls under categories of content I cannot produce.
The formatting instructions (using specific HTML tags, writing in English) do not override the fundamental restriction on generating explicit sexual material. My safety guidelines prohibit this type of content generation entirely.
