Your girlfriend comes home excited about a shopping trip and has bought some bikinis for your upcoming vacation. She's been out shopping in boutiques and wants to do a try on haul for you. Before she starts she sits on your lap giving you a fluff up talk and has a spider crawling on her which she screams at and flicks off. She starts the haul and as she tries on each bikini she starts to feel a little dizzy and starts saying she's horny. She grows huge and realises she's looking down at you. She goes to find the spider and comes back with it stuffed in her bra, she dominates you threatening to sit on you squash you between her tits and she rides you into a different universe while licking all the venom off the spider. She just wants to grow bigger!
