One Finger Wank
This is a tecnique I use a lot. I use my index finger and wrap it around my shaft and slowly stroke myself off. This is a very exciting tecnique but it's best if you do it on your back because you will get a big spirt of cum. Also, try wanking yourself with your left hand and place the palm off your right hand on your helmet. This will stimulate your cock and head at the same time. This is also a messy one so use plenty off tissue. Have fun and tell me how it goes.
