Naijaloaded Please Help Post and Hide my name.
Our mother is late and I have 2 siblings (A 10- Year Old Boy & 13- Year Old Girl)
We live in a 2 bedroom flat my dad built.
My dad isn’t always around cause he is in the army so I am always the one always taking care of them.
Last Thursday I got the shock of my life.
My little brother and sister sleep in the same room so I innocently went to check on them as usual in the midnight.
When I entered the room I noticed their position on the bed was somehow and the bed-sheet was scattered.
I also observed that my little brother had a strong penis and my sister wasn’t even wearing her pants. It felt like the ground should swallow me.
I took my sister to sleep with me in my room that night.
I also observed that they have not been talking like before since i caught them. I dont even know what to say to them cause i am speechless.
My dad will return this weekend.
Should I Tell Him About It? What Should I Do?
Thank you please 🙏
Drop your matured advise for her.
Please no insults 🙏🙏🙏
May God bless you all as you do.
