Actually I was going to ask if there is a preggo ending xD
But apparently not. I could have also looked at the tags but they could be outdated.
Nothing a friendly question wont solve.
Jennifer gets pregnant with Jimmy's baby. There is a final scene of them having sex while she is pregnant. Getting to that scene is pretty convoluted though.
You can't have sex with any other guy, apart from Mark. You have to 'bargain with Jimmy', make sure you get the job at school by 'bending over', call Tim on Saturday and go to the nightclub with him and Laurie ( any outcome with Laurie is ok).
Later in the week, invite Paul upstairs for a drink and when Mark comes home, 'disagree' with him when he suggests Paul should leave.
He'll leave anyway and Jen and Mark have a big row, with Mark storming out. Afterwards you need to call Tim over, until they're interrupted by a text from Jimmy, threatening to send the photos he took of Jen to Mark's phone. Choose to visit Jimmy, and Jen eventually has sex with him.
The following day at school Jen spies on Hope and Luke having sex in the toilets and films them on her phone ( either choice is ok). After school she visits a pharmacy and she needs to take the morning after pill. If she doesn't take the pill, you go back onto Mark's Path again ( don't worry Jimmy will get her pregnant again later). Later at home she remembers the dildo Jimmy asked her to use, to train her ass. Make sure she uses it.
And once that's done, you're locked on Jimmy's Path. You get a choice at school the following day, but either choice still leads to Jen getting a call from Jimmy, to meet him in the evening. This leads to Jimmy's ending which is pretty long.
