My sister was at 'that' age. You know, when she starts being 'hot' and 'beautiful' to all the boys at school. It was making things really awkward at home.
She would bring boys home and I would have to listen to them eating out her pussy as I had my dinner. Sure, she'd still jerk me off while I drank her milk, but it really wasn't the same.
Most of her life I would come home from school and bury my cock in her and drink her milk as we watched TV, but now I had to share her with her classmates. Worse yet, she let them pick the TV shows.
Who do these boys think they are? Hmm? I'm the one whose been keeping her pregnant since two months before she was born. I'm the one who crafted her voluptuous body in our mom. If I were older I'd remind her that as her father I can ground her, but our mom says I'm still too young to act as any of my kids' fathers.
Oh well, at least one of my sister and I's daughters has come over to pacify herself on my cock. The show's not too bad. Maybe I can be friends with this boy my sister brought home… If she's keeping this one.
