Once the flower's proboscis is inserted, the stem retracts and pulls the prey down with it closer to the ground, making it more difficult for the prey to maneuver and escape. The proboscis then begins slowly pumping its contents into the prey's vagina. This substance, a sexual desiccant sap with the approximate consistency of semen, greatly intensifies and extends the prey's orgasm; a necessity since the deeper joining process hasn't yet started and the prey would otherwise be able to escape at this stage.

The sap absorbs into the prey's bloodstream via the uterine lining slowly overtime. The prey's body begins slowly building resistance to the initial orgasm-enhancing effects of the sap, slowly reducing the strength of their constant orgasm over time, but not the orgasm-lengthening effects. From this point forward, so long as the flower continues supplying sap, the prey's orgasm is constant. The sap also contains a mix of hormones - which the flower adjusts as needed to suit its captured prey species - that begin re-optimizing the prey's body. The prey's muscles - especially in the vaginal region - uterus, and other systems are slowly re-optimized to exist in a state of constant orgasm, while also greatly increasing the rate at which vaginal secretions are produced. These alterations begin immediately, but their effects are not immediately apparent.
