Tachyons experiment

Agnes Tachyon the Umamusume has an experiment she wants to try. She has her pencil and paper out ready to take notes. She is wearing her cute school girl uniform and she pulls her tits out to get him hard. His cock is at eye level so she can observe his growing member. She slides it into her mouth and starts to suck on him. She wants him to enjoy her mouth and do what comes naturally as she sucks on his cock. He is so hard she pulls off her panties to let him enter her pussy as she puts down the pad and pencil.
