Washu knew sex was good but this was way beyond that. She knew something was wrong when she looked at the clock and noticed that this 'orgy' has been going on for four hours straight and she' still going on strong and has had not one orgasm release yet. The next thing she noticed was that her sexual desire was multiplying rapidly. What her mind missed was that Mihoshi, Ryo-ohki, Ryoko, and Tenchi via Ryoko were being feed her sexual energy. In addition, that she was feeding them hers in an endless chain, which was in increasing at a frightening rate. So when, a certain Jurain Prince to be remaining nameless (Yosho) power reserves ran out (which was keeping him from blowing his wad ) Blew, it set off a chain reaction that literally KO 3 goddess, 3 avatars, 3 of the most powerful ships in space, 1 GP officer (Kyone passed out earlier), 1 bounty hunter, 1 planet Jurai, and all the tree ships for 6 hours. It would never be explained on earth.

Chain reaction

It for damn sure started with Yosho. However, he was the last one to be affected by it. His sexual release set off Washu's mental release. Which first went to Mihoshi (only because she was in skin contact with her at the time) It caused her to short out so it went back to Washu so now you have:

Now that went to Ken-ohki through Ryo-ohki blowing him out back to Ryo-ohki back to Washu

Out to Ryoko now remember she has been drawing on power from Stonehenge this whole time. Here is were it gets tricky Ryoko Tenchi Tsunami/Sasami Tsunami ship Tsunami tree Jurai Jurai Tree ships then back, knocking out everything on the way back to the three Tsunami's. Tsunami relives all from all three parts at the same time in both ways, which KO's her.

Tokimi gets it from Tsunami, which goes to D3 then back. From her to Washu. At the same time Tokimi received so did Washu and Tenchi. Therefore, when Ryoko got it from Tenchi and Washu she reached out to said bounty hunter. Who just happened to have stepped out 10 minutes ago from behind one of the standing stones? Who currently is in a very compromising position floating above Ryoko? (Bounty hunter had her wrists and ankles bound together bare ass naked with Tenchi's face buried between her legs) she shorted out almost before it hit her. Back to Ryoko to Washu. By this time, it was excessively much for her and she went down.

The last two went down moments later. When Tenchi and Ryoko finally blew (from the feedback loop), the energy level had reached supernova5 levels. The resulting explosive release would have destroyed the Sol system fortunately, Ryoko had been tapping Stonehenge. Which of course it is one of six power points of the planet earth. Being it was it allowed Stonehenge to contain the energy release within its area. The resulting energy release had one unfortunate side effect; E. M. P. the resulting pulse KO every unshielded piece of electronic equipment in the whole system it would have been months before things were normal again on earth. Finally, by then Washu had collapsed on top of Yosho the total time of this event was point nine five seconds.
