Tips?

Me and my girlfriend want to have sex for the first time but she doesn’t have a dildo at her house which is ok because she’s afraid her parents might find it but is there a safe and sanitary way I can get a dildo for her to store for her when she comes over I have no problem getting her one but I also don’t want my parents finding a strap on and yes I’m a adult but I’m trying to avoid the awkwardness if they were to find not one but two dildos and a strap 😬
