The spider had already bound Serel' legs with sticky webs that one could say felt like sticky water, the webs were not covering her legs, the webs were only inbetween her legs, sticking them together and rendering her unable to run, the spider happily attempted to rip off Serel' clothes with it's mouth. Bella purred as Serel stroked her and returned her giggling with her own, obsessed with Serel and therefore not noticing the giant spider.
