Making Do

I'm Henry 34 single and doing quite well in my own business. Never been a lady's man by any stretch of the imagination. I own my home and lived quietly by myself until recently. My sister Suzie 27 lost her job and was evicted from her apartment due to the covid pandemic. I wasn't affected much if any and worked from home mostly. I took Suzie in and she tried to find another job, without any success. This is where I say I'm the greatest stud there is and Suzie is a playboy centerfold. But we're not, I'm overweight and short and Suzie is the plain Jane bookish type. But I do get horny every now and then and while sitting at home finishing some work on a rainy day. I got horny and was going to my room to take care of it. While walking to my room, Suzie asked me if there was anything she could do for me. Without thinking I replied No unless you want to let me fuck you. It was said before I realized and Suzie was shocked at first, but then replied Okay it's time I got fucked. This shocked me and we just stood looking at each other. Suzie then took my hand and led me to my bed, she started undressing and I started undressing shortly after her. We were both nervous and slow starting and after nearly half an hour we fucked for the first time. Then we laid together for a time and then fucked again. After we showered together and stayed naked in the house for the rest of the day. Suzie slept with me that night and we fucked again and the next day she moved into my bedroom and has been there ever since. Now 6 months later Suzie is pregnant and tests show everything is fine. We are happy together and plan to stay together.
