Uncle fucks me... Sister is watching...! Part 1

My sister and I were on holiday with my rich uncle to have a lot of fun. Everything was cool at first, but when we were lying by the pool in our bikinis, my uncle started making obscene remarks like "You've got such a hot butt, I'd love to..." and so on. That became too much for me! I went to my room to relax... a short time later my uncle entered... locked the room and said "Now I'll make a real woman out of you...". He took off his shorts and already had a bulging hard-on, then he held me tight and pushed it into my mouth. Then there was a knock at the door, my younger sister wanted to see me.... She peeping tom through the keyhole and did it herself!!! "What a beast!!... Instead of helping me, she's wanking your pussy!!!" Then my uncle really took to me and blasted my little pussy with his thick cock sooo much that I had to scream... You won't believe what happened next...!
