What to Do

I'm Clay 25 live with my girlfriend Rhonda 21 and her mother Janet 38 widow. I'm financially okay due to trust fund and studying at the local university. I moved with Rhonda and Janet after getting Rhonda pregnant and we're marry at the end this year after the baby has been born. Rhonda wants to finish her studies also and last month Rhonda had lectures all day and my mine finished a lunchtime. I came home and found Janet drunk, which isn't all that strange. She doesn't date and when on time off gets bored and drinks too much. Anyway I tried taking her to her bed and she started playing with my cock thru my pants. Short version I fucked her twice, both times leaving my cum inside her. Rhonda got home about an hour after and I had showered and on her getting home I was ready for more sex. So we fucked and after Rhonda checked on her mother and saw cum dripping out of her pussy. She asked me had I fuck her mother I said she had started playing with cock and so I fucked her. Didn't say I had done her twice, Rhonda then said you didn't take precautions did you. I said no I didn't, well you might have gotten her pregnant as she isn't protected Rhonda explained. The next day Saturday with all of us home together, Janet wasn't upset by me fucking her as reckoned she was horny anyway. But her getting pregnant was a question, what to do about it. I wasn't too worried as I've heard it can take a while to get pregnant and a few more fucks than 2. Especially one after the other, how wrong I was, Janet missed her next period and than the next. After test confirmed she was pregnant and her regularly sharing her bed with Rhonda and me. Janet decided to have the baby, explaining that your pregnant and then saying your a widow. People assume your husband hasn't long passed away and so keep clear of asking too many questions. That's most people not my mother Caroline, but once she knew I was the father she has kept it secret. Especially from my father Henry, luckily Henry doesn't take too much interest in other people lives. What to do, simple what Janet and Rhonda want.
