Lavi struggling even harder and knowing what the ritual is doing to her, screaming at you to note rape her again, as you do so anyway. Feeling you mount her smaller body as she nyahs out in denial, poking her smaller pussy with your engorged cock and thrusting it in sharply. Making her grunt and gag out weakly as you fill her up and stretch her walls painfully to accommodate your new girth. Giving her a few hard thrusts to remind her where she is, coming back to her senses to mewl out in denial and pleasure as you break her pussy anew. Feeling so much better than before, her tightness, your heightened sensitivity, as you cannot help but hump into her with a ravaging! The tendril in her butt trying its best to move through her body, going at it slowly as it has much more volume inside of her than before.<br/><br/>Eventually and quickly unable to help yourself as you try to knot and cum into Mistress Lavi a second time. Realizing what you are trying to do as she mewls out begs and threats and screams, feeling each time as her tight labia lips get stretched slightly from your engorged knot. Getting the hang of it as you keep trying to break her pussy properly and knot her fully, taking a tormentingly long time, breaking down her will, as she reverts to sobbing and gagging from what you are doing to her. Until, at last, you give it to her in one final thrust, plopping your knot fully into her and your cockhead slamming hard into her cervix! Making her double over and grunt like she was punched in the stomach, eyes wide in shock, not giving her any rest as you flood her womb again with your hot seed!<br/><br/>Burning her from the inside all over again as she howls in terror, struggling in vain as you sap more and more of her sexual energy. Feeling her belly bulge as her womb gets overfilled with cum, all the while feeling her busty C cups deflate into an pathetic B cups. Dropping another foot in height as her pussy tightens even more painfully around your cumming shaft. Looking down in horror at her pathetic B cups, being massaged and squeezed by the tendrils, as you finish cumming and yank out of her tiny pussy. Cum overflowing out of it as she sobs and gags from her torment, the ritual still going as the tendril in her butt casually starts humping her gently to get into the mood. Checking out your cock a second time to see that, yes, it has changed again. A second spell circle adding to the first, extending down the shaft of your massive cock. The ritual adding to your shaft once more, giving it a rigid line of backwards facing barbs along the top of your shaft, like the teeth of a saw. The barbs more rigid and sharp to the touch than normal kitty barbs, as fucking a girl with that would drag the barbs across her clitoris and "saw" into it. You could imagine the possibilities this would create in breaking in a girl with these! All the while Lavi sobs to herself, mewling and groaning from the tendril humping her, and begging for it to stop...
