Caring for Bro

My brother was in a car accident and was laid up for months, both his legs had been broken and after leaving hospital I was to take care of him as his only sibling. He has his own home and I rented and luckily my lease was up and so moved with my brother. I still had to go to my job, but I was living rent free and looking after my brother when I wasn't working. Nothing happened at first, I was giving sponge baths and it was during a sponge bath he got an erection. Being the good sister I am, I teased him about and then pulled him off to get it to go down. The next sponge bath another hard-on and hand job. The next sponge bath I decided not to waste a nice size cock and get some pleasure myself. So, I mounted him and rode him until he came inside me. No worries about getting pregnant as I'm on a contraceptive injection to prevent pregnancy. So, fucking my shocked brother gave us both sexual release. Of course, it didn't stop at one. Every time he got a hard-on, I rode him. Once he was up and about again, I had intended to find another place for myself. But my brother asked me to stay with him and we have continued a sexual relationship. But we still date other people, fucking each other is just a special thing we do in our lives now.
