I like to get erect first, then to tie my scrotum really tight. I then wind cooking twine round the base of my shaft: it causes my tool to feel as if it's about to explode and it really reduces its sensitivity. I work only on the head while thinking about having sex with an ex-BBW partner while her sister videos us. (it's just a fantasy: it never happened).

I take it nice and slow for about half an hour then need about ten minutes of frenzied effort to release. I coincide that with the thought of my partner offering me her sister's arse.

The twine reduces the intensity of the pleasure in my my tool but it extends the ejaculation time considerably. It's not quite painful but definitely headed that way and my glans are usually very sore until I bathe them.

The real treat, however comes after the release because my erection remains sufficiently hard for me to pleasure my current partner immediately if she has been watching. I prefer it when she watches because she helps to guide me through my fantasy. But when we couple afterwards, it's just raw sex.

I am usually so desentitised that I simply cannot release again until I remove the twine. My current partner is very multi-orgasmic, repeats quite rapidly, is a big squirter and goes for ever if I can keep up with her. (This isn't fantasy - it's very real)
