I agree gem, I almost always have a sissygasm when I feel their cocks start jerking and feel every shot of their hot cum hitting me deep inside. The pleasure is amazing. More intense than fucking a woman. I was so happy that my wife understood and always helped me with my needs.
Nothing beats the intense feeling you get as another man slides his cock into your ass and proceeds to fuck you until, at last, you feel him cum in you as he pumps his seed deep into your willing submissive body where you both want it and it belongs.
