My first bisexual

I was 16, my first bisexual experience was in my second year of high school with the neighbor guy next door Charles who was 62. On weekends I would help him out sometimes with yard work...long story short one day while taking a break I noticed a hustler magazine on his end table and he saw me glancing at it and the subject of sex came up before I knew it (well actually I knew what was happening) I was laying on his couch with my pants and underwear down to my knees and my cock harder than ever before or equal to my first time playing and fucking my girlfriends pussy. I never thought I would like it as much as I did as he played with and began sucking my cock....I came so hard it hurt but felt great!!!! definitely one of my top 5 orgasms!!! I did clumsily jack him off until he came as he knelt beside me on the floor next to the couch, he shot a huge load and some of his cum ran over my fingers...I loved how warm it was...I didn't suck him off that day but we did get together many times after that
