Since she was secretly in love with her step- bro for a while, dirty minded girl, Shino Tanaka found a way to get down and dirty with him, while parents were not at home, for the weekend. After he had a nice shower, he asked her to bring him something to quench his thirst. She played clumsy and “accidentally” spilled some on his underwear, enough that he had to take it off as soon as possible, because it was very cold. To show that she did not do it on purpose and to make up for her “mistake”, Shino started rubbing his cock and sucking it, to warm it up a bit. It felt very good, so he did not complain at all, as long as she was doing her thing.
