Sexually Frustrated Stepsister

My stepsister Riley is nothing but trouble, and I'm not complaining! We've fooled around before, but now's the chance to really fuck each other since step-mom and step-dad aren't around.. She grabs my hand and pulls me towards her natural petite body. 'I want you so bad..' She looks at me with her big blue eyes and pulls my cock out to suck on. I sit back and enjoy her lips wrapped around me, stroking my cock as she blows me. Riley turns around and bounces her ass on my fat cock, I love seeing her pussy lips spread while she fucks my dick. I turn my little stepsister over and pound her tight pussy until I'm about ready to cum! My stepsister sits up and opens her mouth wide for my big load!
