Watched my mom having sex

I never imagined this side of mom that she can is even like this . I dont live with my family i live in other city so i was there at home .

It was around 1 am at ni8 i was just using my phne everyone was asleep . I was going to washroom , while going to washroom i saw my mom room light was on and some sound was coming so i just peeked through the window as window was slightly open . I could not believe what i saw through the window or would have not imagined . My mom was half naked was just in blouse and petticoat and my dad was laying on bed and my mom was sucking his dick . I froze and was seeing at first it was embarassing but suddenly the moment turned hot things started getting heated and i cant forget that night what i saw after that . Never thought about this mom ger moves her expressions her ways her passion towards it changed my whole view towards her .
