Going To The Adult Sex Store With My Sister

So I’m 21 and my sister is 20 and she asked if I was willing to go with her to an adult sex store. Apparantly she has always been inetrested in going but never alone, thus the invite. I did ask her what she plans on buying and she reponded” she plans on buying a dildo and a vibrator” and If go with her she will buy me anything from that adult sex store. Even though I’m also nervous going to such a location with my sister I also want to try out a pussy pocket or one of those toys that give you head idk. Have ya’ll gone to a location like that with your friends or siblings?
