Ever since Tenchi and Washu got it on, Washu had introduced Tenchi to S&M. Washu loved S&M. So, Tenchi and Washu traded the role of slave and master (or mistress in Washu's case). Washu said that it was good for Tenchi to learn all the kinky stuff about sex, and S&M was the kinkiest kind of sex of all. Tenchi was fast becoming a expert in sex, and showed it in bed. Washu and Tenchi tended to have thier dates every other weekend...or sooner, depending if Ryoko and Ayeka were fighting. So, it was Tenchi's turn to be the master. And seeing Washu at such a tiny size made Tenchi wet. This would be the ultimate form of S&M. Without a word, Tenchi grabbed Washu's platform and plucked Washu off of it. Then he placed Washu in his underwear, where Washu got a good look at Tenchi's phyton up close. The soon-to-be rock-hard prick was limp and bigger than Washu herself. Washu started to rub her body against the limp member.
Tenchi walked out of the lab. By this time, Ryoko and Ayeka's fight had been moved to outside. Tenchi heard explosions on the outside, but he ignored them. Washu was giving him a hard-on with her rubbing up against his prick. Nobody in the Masaki house noticed Tenchi going upstairs. Tenchi entered his room and locked the door. Nobody would disturb him this night.
Outside, Ayeka was at the buiness end of Ryoko's attack. But, Ayeka blocked it with her force field.
"Just give it up, Princess Tubby!" yelled Ryoko.
"Go to hell, flabby pirate!" yelled back Ayeka, sending an energy ball at Ryoko.
"Girls, girls!" said Kiyone. "stop fighting! You two fight over every little thing"
"WE DO NOT!" yelled Ayeka and Ryoko together. Kiyone sighed.
