Returning home to Mother

I'm George 26 eldest of 2 and after being away in the Army return home to stay with divorced mother Karen 44. My sister Joanne 23 is married and lives in another state and my father Donald left us when I was 12 and hasn't bothered to keep in contact with us. Karen works in the local supermarket and has her own 3 bedroom 1 bath house. I entered the army as soon as I was old enough and trained as a mechanic. So on my return home I got a job at a trucking company and was intending to stay with till I found my place. But things changed when I came home a little drunk one night and feeling rather horny also. I made pass at Karen and at first she rejected me, but I continued to trying and she finally let me fuck her. The next morning she woke me up by sucking on my cock and then mounting me. Since then we sleep together and have sex, but Karen wants me to find a wife and has started bring home from the supermarket in the hope I might start a relationship with one of them. That's how I met Jenny 23 and I took her out several times and started fucking her. Karen liked Jenny and I really like her as well and last new years eve got her drunk and into bed with me and Karen. Jenny got pregnant and we married in March and Karen sleeps with the both of us almost every night since then.
