Short Story

I left home at 15 and struggled for a while, then got a break as they say. I got employed in construction and was sort of adopted by the owner of the company. I was the son he never had, working for him straighten me out and at 28 I inherited his business. Having no relatives and me being like a son to him he left me everything. Nobody thought it strange as most thought I was his son. No well off I decided to make amends with my family, only to find most had died in the 2020 pandemic. Only my 2 younger sisters were left, the older one 24 caring for the younger one 22. My youngest sister was handicapped from birth only one fully developed arm and both legs stunned. With my return I was welcomed back warmly, I'd both come to live with me. Due to their struggles, they hadn't developed any personal relationships. Being back together meant, were bonded more than normal siblings usually did. A very close bond led to me fucking my older sister, I'd been to a party and returned a bit drunk and horny. Started cuddling my sister and ended up fucking her, found together next morning by our younger sister. She was at first shocked than upset as she hadn't been included. I solved that by fucking her and my older sister again. That compounded my actions, as I hadn't taken precautions with either. But the deed as they say was done. Both got pregnant, which shocked me, I'd heard you can't get a virgin pregnant on their first fuck (old wives' tale). Both had been virgins; at most I might get my older sister pregnant as I fucked again after my younger sister. But once was enough, with both very willing to please me and them both getting pregnant. We act as if we're married and will very soon have a son and daughter. No plans to stop our sexual relationship as both babies are fine no health problems according to all the tests.
