``Would you like to do a simple part-time job developing a clean toilet seat?'' I asked a female college student walking around town to observe her anus. After hearing about her experience with anal sex and her usual lower body situation, we meet the female college student's beautiful anus. While measuring the expansion/contraction rate, size, position, etc. of the anus, I licked it and monitored it to reproduce the soft touch of a washing machine. After licking her anus relentlessly, she teases her with cunnilingus, calling it a bidet check. Once the anus is licked up, the pussy is ready! ! After this, the staff seemed disgusted and fucked me.
