Detergent Bottle Top

I've just discovered another method of wanking. You need the top off a liquid detergent bottle, the type of detergent for washing machines. I was about to throw the empty bottle into the recycling when I noticed the bottle top might fit over my cock. It is about 70mm deep and of a diameter that fits neatly over my cock, 42mm. It was kinda tight and created a nice suction when I slipped it over the top of my cock. I pushed my cock to the end of the bottle top and it was a lovely fit. I then tried to get it off which created a great suction. I then proceeded to pull the bottle top up and down. I went online and wanked to porn. After about an hour, with edging, I needed to cum badly. So I increased my wanking rate, which created a nice suction, and then I couldn't hold back any longer and came a huge load into the bottle top. The pulsating of my cock inside the bottle top was incredible. As my cock was a tight fit inside the bottle top, all the cum went inside with no leakage. It was wonderful. I was so horny I then licked some of my cum out of the bottle top but didn't drink the lot, only a taste. Drinking cum after cumming is a little bit of a turn-off although I've done it a few times now. My cock is hard again reading my own technique, so I'm going to have to do it again...
