He makes a few adjustments to himself.

Jaune picked up the Note again, looking at the rules another time, reading rule 6: Physical changes can be made to a person by writing their names in the Note followed by the desired changes. The restrictions are that these must be attractive to the writer, and they must be biologically possible.

He smiled as he wrote, "Jaune Arc will no longer be able to contract or transmit any STDs or STIs. He will also not impregnate any girl unless he desires to. Furthermore, he will from now on be able to last as long as he needs to during sex to give a good time to any girl, and lose his refractory period."

He felt a bit of a tingling sensation over his crotch, and grunted, realizing it was the physical adjustments being made.

Ruby looked at him in confusion, but still waited for further instructions. The sensation passed, and Jaune smiled as he considered how to enjoy the main course, noting he had about fifteen minutes left.
