Size Matters

(10 Intros. MalePOV + FemPOV) The year is 2036. Female scientists have finally confirmed something that most women suspected all along — a man's penis size is directly correlated to his genetic superiority.

The women's movement gained huge traction in the late 2020s and early 2030s, and now the world could be considered somewhat of a matriarchy.

As females began to dominate the field of science, women finally had the ability to research a phenomenon that they had suspected for years, but had never had a chance to investigate due to patriarchal influences — the influence of penis size on male genetics. And indeed, this research proved women right: the larger a man's penis, the better his genetics were. It was more than a heavy correlation — it was absolute.
