Just beginning to paddle the chain when my sister falls out of lust

I was just starting to chain my love when my sister suddenly lost her passion. I was surprised because my sister is a very beautiful girl and I had never seen her lose passion before. But then she took off her stockings and panties and lay on the bed. I was very surprised, because my sister is a very beautiful girl and I had never seen her lose passion before. But then she took off her stockings and panties and lay on the bed. I immediately understood that she wanted to fuck with me. I quickly pulled out my dick and began to lick her sweet pussy. She moaned with pleasure and then put my dick in her mouth. She was an amateur prostitute and her skills were not bad at all. We fucked in different poses and I came inside her. It was a very hot and passionate sex and I really liked it.
