Just a little knotty

A quick cross reference and you begin to dabble in a little biological augmentation.

• Men and futas have a secondary erectile state that triggers at the onset of orgasm. This secondary swelling causes the tissues of the head of the penis to swell 2 to 3 times its initial size and extend a "crown" of soft spones to lock the penis inside the vagina or annus. Durring the issuing orgasm the spines vibrate stimulating the surrounding tissues. This secondary erection can lsst from 1/2 to 2 hours and can be ended early through a concous decision.

  * Men and Futas testicles and seminal glands only begen producing fluids during sex. The longer sex lasts the more flueds are accumulated. Normal amounts can be up to 1/2 pint of fluid from both pre and during orgasm production.

* Women and futas have a "pouch" in there vagina just in front of the cervix that is created buy a sphincter of tissue that "catches" a penis head during its secondary erection and acts to lock the couple together. During orgasm this pouch swells and pulses. In the final days of pregnancy this pouch looses most to all of its sensitivity and the sphincter becomes loose and pliant allowing for an easy birth.

A quick glance to check the new rules and you set the new changes.
