While Krillin plays with his daughter, Number 18 has to put up with Master Roshi, she, although she doesn’t like it, lets him touch her so they can live there without problems. Master Roshi uses her whenever he wants, he calls her to the bathroom to suck him off and Number 18 obeys him, at night he enters her room and stimulates her, making her cum and wake up completely wet.
Every day without fail Master Roshi delights himself with Number 18’s body, he sucks her vagina, her breasts, stimulates her from one and other, despite her desire for Krillin, he usually has little time to please her, that’s why she has let Master Roshi touch her without stopping him.
One day while she was masturbating while watching Krillin sleep, Master Roshi arrived ready to take advantage of the situation, but even though she said no, the Master still took her, put on a condom and penetrated her, reaching deep inside her vagina until he cummed without her being able or wanting to stop him.
From that day on their relationship changed, every day was more frequent, Master Roshi provoked her more often and they fucked more frequently, 18 put on more and more provocative clothes until it reached a point where they both fucked every day without stopping, and without caring that Krillin saw them, in the same way, there was not much he could do more than just watch them while they both fucked.
