Struggling as best as she can while bound by the ropes, eager for this horror to get over with as she screams each time you plunge your enhanced puppy cock back into her butt. Tensing up painfully hard with each new thrust inside of her, gagging and foaming at the mouth, while trying her best to retain her sanity. All the while using her position on all fours to try to help out as best as she can, meekly humping back into your crotch to goad you into filling her butt with your magic cum and give her a lewd body. All the same, Lisa watches on with lewd interest, getting off on it with sinking her fingers into her aching pussy. Adding her moans to her sisters lewd cries of agony, giggling in occasion at the thought of her being turned feral thanks to consensual anal humping.<strong>"Hurry up and turn her feral already you perverted puppy! Watching that happen will surely give me a intense orgasm! Nyah!"</strong>Nina nyahing out in denial between her gags and cries of agony,<strong>"Nyaaaahh! Don't turn me feral! I'll kill you if you do! Nya nya nyaaaa!!"</strong>
