I sucked my husbands nipple

Last night as me and my husband were BD he asked me for a certain request. Now take this a count I never thought not knew that other men were into this ! And you know I'm not really into this I just did it to see his reaction because I thought he was kidding. SO I SUCKED HIS NIPPLE. It was a new experience for me and him he got quite happy from that and well I got happy aswell to see my husband that happy but personally I don't think I'll ever do it again .
