Anna hang there dripping eggs and cum out of her pussy for the next half an hour. When no more insects came to lay inside her, the same vine from before pushed its way back inside her pussy. Any errant eggs were collected by the flared tip and were forced inside her womb where the vine sealed it from the outside this time since there wasn't enough room left inside her for it to seal the normal way. A small protuberance from the vine inserted into her womb and began secreting fluid inside her. This fluid was used to dissolve the eggs inside her womb and break them down into nutrients. Although it couldn't do it on it's own. Anna had been tortured on the brink of an orgasm for the better part of a day at this point. Her ass, pussy, nipples, and even urethra were all in various states of plugged, bullied, tugged, or stroked. Anna was losing her mind with pleasure and all of her holes were begging to be abused if it just came with the promise of one measly orgasm. She just wanted release from the torture of being used like a fuck toy by a goddamn plant and insects. With a womb and bladder full of insect eggs, and a womb being pumped full of enzyme; now was the moment that the plant decided she was allowed to cum.
All at once all the pleasure she had built over the past day exploded. Anna's body contracted painfully and all of her holes squeezed hard on their vines. A few eggs that didn't quite make it out of her urethra and ass squirting out from the pressure. Despite the knot and the seal on her womb, liquid gushed out of her ass and pussy from the pressure of her orgasm and the vine sealing her womb had to work overtime to keep the eggs and cum from spilling out of her womb and rushing out of her. Mana and essence flowed out of her into her bladder to help strengthen and feed the brooding eggs planted inside her from the vinereaver wasp. The nutrient solution injected into her bladder by the vine supplemented the eggs and acted as a carrier for her energy.
At the same time, excess energy leaked out of her into the enzyme being pumped into her womb activating it and beginning the process of breaking down the eggs the other species laid inside her. The vine inside her urethra dissolved it's knot and retracted nearly completely--each bulge scraping the inside of her urethra clean to ensure no other species managed to lay inside it's territory--before it began slowly stroking her hole to keep up the pleasure while the vines around her nipples pinched and tugged them. Anna's orgasm wasn't ending any time soon. The plant could keep her in a state of orgasm for more than half an hour at a time to extract the most energy from her as possible. Any more than that wasn't worth it and the plant could in fact extract more if it tormented Anna for a while preventing her from cumming until it released it all at once.
