She Grabbed & Pulled. Then I Fucked.

There were sounds of a couple having sex, and the unmistakable moan of my sister in law. She muttered "fuck, that's hot". I peeked around the corner and she was laying on the bed, naked, fingering herself while watching a porn video on her phone. It was too much form me. I couldn't take it anymore and fished out my cock and started stroking, watching her. 

I thought I was doing a pretty job of being quiet, but at one point I moaned without meaning to. I stopped and she moaned from behind the door, apparently oblivious. I kept tugging on my cock and while I was positioning myself to get a better view, my hand hit the door. I ducked back behind the door and froze, my heart pounding in my chest. The sounds from the room continued. 

After a few moments I regained my courage and peeked back around the door. I was face to face with my sister and law, who was standing there naked. She simply smiled and grabbed my hand and pulled me into the room, closing the door behind us. 

My hard cock was still hanging free and her eyes dropped down to meet it. "It seems like you like what you see." I confirmed that I did. She told me that if I wanted to watch, all I had to do was ask. "But, now that you're here, let me help you with that..."

She dropped to her knees and took my cock deep into her throat. She sucked me and swallowed my cock in a way that could only be described as amazing. I warned her I was about to cum and she picked up the pace. I grabbed the back of her head and forced my cock down her throat as I erupted my balls down her throat. Like a good girl, she moaned, swallowed it all, and then licked her lips. 

She stood up and kissed me full on the lips while my hands explored her nubile body. I grabbed her ass and lifted her up and carried her to the bed. I tossed her onto her back and crawled between her delicious thighs and buried my face in her pussy. In short order she was moaning and writhing on the bed. I was worried she might wake the whole neighborhood, but I also didn't care. My sole thought at the moment was to give her pleasure. She grabbed my head and shuddered as she cried out "Oh, fuuuuuuuuuuuuuuck!" as she came all over my face. 

She smiled up at me and said thank you. Then she noticed my still-hard cock. She turned around and got on all fours and wiggled her ass at me. I didn't need a second invitation. I knelt behind her and rammed my cock into her pussy up to the hilt. I fucked her hard and deep with long, slow strokes. She was crying out with pleasure. I pushed her flat on her stomach and continued fucking her from behind. She screamed and moaned into the pillow. She turned her head and yelled at me to empty my balls into her twat, I happily obliged. 

I laid on her back for a few minutes as we both caught our breath, then I pulled out of her and laid beside her, my cock still half-hard. She rolled over and took my cock into her mouth again. Between licks and sucks she told me that she was cleaning me off. Then she let out an evil chuckle. I asked her what was so funny and she said that next time we should include her sister...
