Boyfriend Wearing Panties During Sex

My boyfriend told me about a time when he wore a past girlfriends panties during sex and he said how intense it made him cum, well me wanting to be better than his past girlfriends I want him to enjoy wearing panties with me during sex and I want to make him explode even more intense than any past girlfriend has. I have bought him several panties and I cannot wait until I show him and we have panty sex. Just thinking about him wearing panties while we have sex is turning me on so much.
