Write a lewd story like this: Someone put aphrodisiacs in NAME_1's coffee, making him horny when drinking so he had to go to the toilet to masturbate (detail how he feels horny). When he returned to the desk, he only thought it was a physiological need, completely did not think that there were aphrodisiacs in the coffee, so he continued to drink it. As a result, he felt hot again and went to the toilet to masturbate again. Actually he didn't want to masturbate, but the aphrodisiac forced him to.
