Brother And Sister

It was a normal Saturday evening. My mom at work and my sister watching TV. Sometimes I'd watch it with her just like today. I walked into her room and sat on the bed next to her. She was wearing a light blouse with no bra. Her beautiful breasts were very visible. She leaned on my shoulder and her tits lowers on my chest. "Maybe we can have some fun after the show" she said into my ear. I was so shocked by her comment but I let it pass thinking that she was meaning something else. After the show she started getting a litter flirty. "What gotten into you sis?" I asked her. She said nothing and reach for my shorts. She quickly pulled then off.
Then she put the head of my cock into her mouth. I was about to stop her as this was very wrong but I just couldn't. I reached my hand down her panties and teased her. I slowly slipped a finger in her cunt. She moaned in pleasure also rubbed her clit. She massaged my my balls and I grew to a full erection. Part 2 coming soon
