I did that from my teens into my early forties! Not limber enough anymore! Loved it! Accept the sore back and neck it would give me. On my best days I could even stretch my ball sack close enough to lick a little! I loved to twist my cock a half turn while it was soft enough because I really loved how it felt to feel the head sliding across my lips in that position. Basically it was entering my mouth they way someone cock would if I was kneeling between there legs rather then the normal self suck orientation which would be similar to 69ing with a man. I I initially just wanted my cock sucked but during those year I started to sometimes fantasied about sucking another mans cock! That did finally happen a couple time (so far) in my 50's. I was dressed fully enfem and truly loved it!
