The physical, psychological, and spiritual saturation point of any male or female in the acceptance of male genetalia (or any suitable substitutes) in or on any part of the body. This threshold varies depending on the person and the extenuating circumstances of his or her engagement.

The critical cock capacity (c-cubed) is a constant that when multiplied with mass, equals energy. The proposed model for this interaction is E=MC^3.

Researchers have made conflicting claims on the range of C^3. Some believe the bottom limit is as low as 5 or 6 while others have proposed upward bounds of 17. As one Harvard researcher proclaimed: Back at Hahvard, the sky was the limit.
Egads! That girl has reached her critical cock capacity! Please refrain from administrating more cocks, as it might result in permanent damage.

My fiance has a higher critical cock capcity than yours.
