I too was in my 40’s and began thinking about sucking cock…l think it just hits some of as we get older. Had played with dildos with my girlfriend, sucking, sharing my cum, anal. She knew l was interested and we talked about it frequently. She told me if l really wanted to do it she could make it happen and would even help me. l agreed. About a month later she set it up and l sucked my first cock with her. Since that time l have sucked several cocks with her and she even encouraged me to go solo.
