My Chubby Niece

Christine 23 is chubby and has low esteem, shy and quite timid with strangers. Anyway I'm Bobby 34 her uncle youngest of 4 and Christine's mother Barbara 41 (war widow)is the oldest of my siblings. Christine came to the city to attend university and then her dorm was damaged by fire and she needed another place to stay. Luckily I lived in the next suburb in a 3 bed 1 bath cottage, I work from home mostly not married and in and out of relationships and at the time I had just finished a relationship. So as a stop gap Christine came to stay with me, everything went along as usual for except now I had Christine living me. Quiet as a mouse Christine was and if you didn't see her you wouldn't know she was there. One day I walked into the bathroom to pee, Christine was in the shower and it had frosted screen so I just peed and was going to go. When Christine finished her shower and opened the shower screen door and she saw my cock and I saw her naked. Both shocked at first, I recovered quicker and was somewhat horny at the time as well and so I made move on Christine. She just let me do whatever I wanted and with her not resisting we ended up on my fucking. After which we laid together for a time and I got aroused again and fucked Christine again. That was the start of regular sex between us, I get horny and fuck Christine. Only one thing she wasn't on any protection and got pregnant, we only told Barbara. She wasn't frilled that her brother has fucked her daughter and got her pregnant. But it was too late to care about that, Christine was her real worry. Barbara had Christine tested and every test showed nothing wrong and so Christine wanted to have the baby. Which was how she was raised, anyway Barbara got transferred to be closer to Christine. Christine was now sharing my bed fulltime, Barbara soon joined us in threesomes and she got pregnant also. Albeit on purpose to keep in the family and keep me secured to both her and Christine. Her tests gave us so worry, but also came back okay. Christine had a daughter we called Maureen after our grandmother, Barbara is due in May and is having a son and is to be called Henry after our grandfather. The wider family still don't know the father of their children and we will keep that way as long as we can.
