ok, so the dude is not really want his girlfriend (black hair female) has the pant. He is tired of her aggressive when they has sex and he have to do the cooking all the time. When he meet the nice girl (brown hair girl) he's thinking he would has the pant if he has relationship with nice girl. This girl is looking as good as his girlfriend but she is kind of innocent, can cook well.
The girlfriend try to cook and fail. The two female are in the same college/university. The girlfriend is teacher, the nice girl is student. The girlfriend want to let the dude take more aggressive in their sex role but he is tired of her.
A fire at the apartment complex of the nice girl, she has to stay over at her friend apartment but the girl is having sex with men so she run away.
The dude run around saw the nice girl apartment, called her take her to his apartment, the girlfriend keep the nice girl with them.
The nice girl does all the house work (cooking, laundry) while she stay with them, the girlfriend notice how the dude look at the nice girl.
The nice girl saw the dude carry the girlfriend while they naked out of the bathroom. The dude fantasy about the nice girl, fantasy about the nice girl with the girlfriend in 3P. The dude got (lucky) when saw the nice girl change clothes while he chased after the vacuum robot, she want them to have sex. But he cannot get hard.... lol
The dude and the nice girl has a date, they saw the girlfriend on TV interview, she said something the make him (sad), most like like she was asked if she has boyfriend and she said she does not. The dude and the nice girl get in hotel, and do sex, his dick still not hard enough, the nice girl try her best, he get hard then cum from her tit job.
The dude and the nice girl fuck. The girlfriend show up after they finished fucking.
The female do some yuri teasing, then they has 3P after that day. The female play with each other while the dude not around.
The dude found out that the nice girl was not as innocent as he think she show.
...
Don't know what this will goes. The dude stay with the more aggressive girlfriend or stay with the nice girl with bad past.
