My father, cousin sister, grand mother and mother caught me mastrubating

Believe me I was caught mastrubating naked by my mom, cousin sister and grand mother yesterday.

I am 21 yrs old. I am from India. I am really embraced yesterday.

Yesterday my mother (43 yr) and sister (20 yr) went to Temple. They locked the house from outside. There were me and my grandmother in house. I was mastrubating in our drawing room. First my grandmother caught me naked. She scolded me and said she will tell about this to my father and mother.

I was trying to cover my penis but then my mother and sister came. And I was standing there naked with spermy penis.

I wanted to run to other room but my angrily told me stay there. She slapped me. I wanted to hide my penis with oil bottle. But the penis was really visible. Then my sister had mobile on her hand. She took some pictures.

My mother didn't let me wear clothes. I was naked for 5 hours in front of them. Then my father came then he beat me with shoes and belt. Then he scolded mom as I was naked for long Time.

The worst thing is that my cousin sister had seen me naked. She is sending me my nude pics to me via WhatsApp by saying playing football with toothpick. As I have hernia.

My parents are not taking to me.

Please tell me what to do. I am guilty and ashamed.
