wife peg husband

loved your pegging discussion video on youtube. I became interested in pegging after my uninhibited sister told me she pegs her husband.
I was really surprised because her husband does not seem like the type that would be into taking it up the butt!
My sister said that wives boning their husbands with strap ons is a lot more common than you think. My husband has never mentioned anything about being interested in this.
My sister said "Trust me. Once they realize how good it feels to them they will start asking for it"
I want to peg my husband, but I don’t know how to bring it up to him.
