In Dragon Ball Online , it is shown that as a scholar Gohan became devoted to studying and researching the nature of ki and begins researching the martial arts of the past, organizing them in his book Groundbreaking Science in Age 804 . The book became extremely popular and introduced the concept of ki to the general population of Earth sparking a renewed interest in the martial arts and fighting. One of the articles, " Katchin Can Be Cut! ", had an immense influence on his brother and Trunks leading them study swordsmanship which allowed them to develop their natural potential via intense training and as adults Goten and Trunks founded the Kikoukenjutsu Sword School . The renewed interest in the martial arts also lead to the founding of the New Turtle School by Krillin and New Crane School by Tien Shinhan . As Goku and Vegeta had left Earth to settle their rivalry in Age 801 after Goku realized his death was imminent, it was left to the remaining Z Fighters Gohan, Goten, Pan, Trunks, Krillin, and Tien to defend the Earth after the remnants of the Frieza Force invaded Earth following the death of Gohan's father-in-law Mr. Satan whom the Guard troops that lead the army assumed had defeated Frieza. Like he had in the past, Gohan resorted to using his old alter-ego Great Saiyaman to defend the Earth and managed to convince Pan, Goten, Trunks, Krillin, and Tien to disguise themselves with Saiyaman-like suits as well to hide their identities while combating the Frieza Force, however their ki-based fighting style became a hot topic and global interest in ki escalated. As a result, Gohan in his role as a scholar and Z Fighter ended up sparking a martial arts revolution on Earth and secretly continued to defend Earth with his family and friends as he had done for most of his life.
He was rock hard as he slapped his cock off my ass and grabbed my jock strap and teased my hole with his cock, resting the cock head at my hole but as I pushed back he pulled away. He lay down on the bed and told me to eat his hole, he loved to be rimmed and he had a perfectly shaped bubble butt and pink hole that I enjoyed eating out. After some time he turned over and reached for the condom while I went down on his cock and balls "Get off my cock and lick those balls you pig" were his instructions, I worshipped his low hanging balls full of his seed as he wrapped a thin feel condom over his manhood. I must admit my hardon flopped a little as I saw the rubber go on but I knew this wasn't going to happen otherwise.
