0 to 2.5, a factor of 2.5.My previous optimal rate of 15.45 seconds per 100 meters was - as far as energy supply was concerned - now 2.5 times faster, so 6.18 seconds per 100 meters. Energy supply was no longer the limiting factor; instead I was now mechanically limited, so could run at my maximum possible sprinting speed for as long as I wanted.]]^I spent the last part of my experiment sprinting as fast as I possibly could. I kept it up for fifteen minutes with no sign of fatigue, being amazed at the improvement. I'd been hoping to be able to run noticeably faster, say 5 or 10%; but endless full-tilt sprinting was amazing.I'd been worrying about someone seeing me run so fast for so long, so I'd been running an erratic course rather than repeated laps around my home's block, and I'd also been looking around in case some curious person was following me in their car. There'd been no sign of problems, but after fifteen minutes I didn't see that any risk was worthwhile, so I slowed down. When I go home he was on the couch in his underwear that outlined his dick prfectly considering they were boxer briefs. He was sweating and was fanning himself with a notebook, so I asked why the hell are you doing? He said he ran home cause he wanted to rearange our room. Which was great for me cause I wanted to do it for like 3 weeks. When I seen the room I almost died he had moved Both our beds together which got me horny. He asked if I minded sleeping together and I said nahh its cool... Trying to hide exitment, he said cool and went to take a shower this gave n a chance to look at his sex calender my twin is kinda know for being a manwhore I never knew why though. When he got out Of the shower I got in, he left his clothes in the bathroom which wasn't unusual so I went through it and got a hard on so I jacked off in the.
