My Quiet Little Brother

I'm Patty 37 divorced 2 years ago last week, needed a place to live with my then 3 yr old daughter Katie, my ex husband Donald and I split our assets and parted ways. No alimony as he left the country quickly before the final verdict was handed down. It was a mistake to split the cash before the verdict, unable to contacted I was left with money and a 3 yr old daughter Katie to care for. Lucky I had a younger brother as our parents are deceased, my brother Gavin 34 is a very quiet person by nature and at 6'2" of a solid build, exercised and done karate as a sport and worked in software development and earns good money. He lived in the next state to me and so I rang him and then went to stay with him arriving just before the first lockdown started. Gavin never married and kept to himself only had a dog Winslow for company. He lived in a 4 bed house on the outskirts of the city and avoided crowds as much as he could. Katie took to Winslow straight away and they became so connected you would think they were joined at the hip. Never apart from went we arrived till today. I was a little upset over the whole affair and at first just wanted to be alone with thoughts, Gavin gave space as they say. My little brother as I had always called even those he was taller than I was, made sure we were both okay and got everything we needed. With Katie Winslow was about everything she wanted. The lockdown didn't change Gavin's life much at all he could and did work from home and I kept the house and done the cooking and laundry. Which was a busy at the worst of times, so Gavin started teaching to use a computer better. I could use one but at basic level. As the lockdown progressed, I started getting a little horny and wasn't having much success masturbating myself. So one night laying my bed and having trouble getting myself off, I decided to visit Gavin in his bed. I entered his room he was asleep and I got into his bed with him and started feel him up. He awoke yo me stroking his hardening cock. Still not fully awake asked what I wanted, I said a good fucking, his reply was what and I repeated a good fucking. Now fully awake his cock hard and in my hands, he just looked at me and then said okay. We fucked twice before I let him go back to sleep. In the morning still bed together sleeping, we awoken by Katie who came looking for me. She wanted her breakfast and Winslow jump up the bed and was joined by Katie. I was totally naked nd so I told to take Winslow to kitchen and I'll come give them their breakfast left with Winslow and got out bed dressed and gave them breakfast. Gavin ha his as well, after breakfast was over Katie and Winslow watching TV. Their favorite Sunday morning activity, I took Gavin by his arm back to his bed and we fucked again. Of course I had been really horny and hadn't thought it thru and wasn't on or took any precautions myself and hadn't given Gavin any time even to think about precautions or even use one himself. It was couple of days later that remembered I should take precautions. Gavin didn't think he should as he thought I must be doing something in that regard' I hadn't and that's how Katie got her little brother Robert after our late father and little is healthy no problems. Also after that first night, I haven't slept anywhere else except in Gavin's room. Katie thinks of Gavin as her Father and seems to have forgotten the ass named Donald.
