A near-doughnut experience
This week contained two long and two short pumping sessions.

During the first long session, at monday night, I first pumped during 30 minutes watching an interesting documentary. This was the first time I pumped while doing something completely different. I noticed that this was something like pumping a flaccid penis. I pumped at 5 inHg but hardly felt the pressure straining my penis at all. And when I cycled the pressure my flaccid really became flaccid inside the cylinder. Then I took a 30 minutes break while finishing watching the documentary and massaging my flaccid little friend a bit.
Then I felt that it would be nice to do some proper pumping, so I started a porn movie and pumped for another 30 minutes with an erect penis at 5 inHg. Very different feeling. After this second turn in the cylinder I continued watching sexy people fucking each other on my tv while I edged for 15 minutes. A little bit in this edging I came very close to coming and squeezed my PC muscles as hard as possible... and out came one squirt of cum that flew in a beautiful bow in the air and landed on my belly. I managed to hold back, but as I continued edging very carefully I was very close to climaxing the whole time, cum continued to ooze out from my very hard cock - which became very messy and sticky and all covered in pre-cum. So I had to finish with a shower before going to bed. Did some edging in the shower too... and was extremely close to climax there too, but managed to hold back.

A couple of days later, on thursday night, I was in the mood for a similar session. So I warmed up with 30 minutes of pumping at 5 inHg while watching another interesting documentary. Managed to get a good erection before starting to pump this time, and the erection did not completely go away during this session.
After a 30 minute break I felt for pushing my limits a bit and decided to try 30 minutes in 6 inHg while watching an amateur gang bang orgy with two horny ladies handling several happy men. It felt really good in the cylinder, but after these additional 30 minutes my cock was really pumped up and when looking at it and feeling it I was certain that I would wake up with a doughnut the next day. I massaged it for a little while, but did not do any edging this time.

So... waking up the next day I carefully looked at my penis... and... no doughnut :-)
But I learned that this was a little too close to my limit currently. Will be a little more careful some time now before trying a similar session again.
Rested from PE a couple of days after this.

* NOTES for week 14 *

Monday night: 30+30 minutes at 5 inHg, 30 minutes pause. 20,0 cm (7.87 in) in cylinder. Ended with 6 inHg and 20,2 cm (7.95 in) in cylinder. Afterwards 15 minutes edging.
Wednesday morning: 15 minutes at 6 inHg. 20,1 cm (7.91 in) in cylinder.
Thursday morning: 10 minutes at 5-6 inHg. 20,0 cm (7.87 in) in cylinder. Directly afterwards BPEL = 19,5 cm and MSEG = 13,5 cm.
Thursday night: 30 minutes at 5 inHg, 30 minutes pause, 30 minutes at 6 inHg. 20,2 cm (7.95 in) in cylinder. Directly afterwards BPEL = 19,8 cm (7.80 in).

Remark: 4 mm has been added to all in-cylinder measurements since they have been done with an extra latex sleeve mounted on the cylinder. This adjustment gives values consistent with measurements made before this extra sleeve was mounted.
