Using Her Toys

I have a kink of buying my GF vibrators and toys and she likes it so we have a deal that I can buy her toys anf pay for them but she has to let me use them on her and do what I like with them to her since they’re my toys and we have a agreement that I buy the toys and she gets a orgasm out of them. Normally we will lay in bed while she sucks on me and she lays with her legs open and lets me have my fun
