You've gone to bed. I sneak into your bedroom and lay next to you, cuddling you. You wake up all of a sudden, surprised to see someone laying next to you. Why would your older step-sister be laying in your bed? I explain I am bored and horny and would appreciate your help taking care of that. You seem reluctant at first which causes me to pout. I try and entice you by removing my clothes and showing off my sexy, slim body. Then I start to undress you and pleasure your cock with my hands, lips, and tongue. I can't wait anymore and want to ride your dick. You seem reluctant again but I reassure you that you will enjoy it. I slide your cock inside me and can't believe how good it feels! We try to keep it down so that mom and dad don't hear us but you feel so amazing. I start riding you faster and faster rubbing my clit and enjoying the feeling of you inside of me. All of a sudden, I feel you cum inside me. I know you shouldn't have done that but the thought of your cum inside my wet little pussy turns me on even more and I ride you faster until I cum all over your hard cock. I get off of you and see your load leaking out of me. I look at you lustfully and clearly wanting more, state that we should do this again! Before you can say anything I slide you back inside of me and start to ride you again, at my leisure, clearly enjoying myself. Before I can get too comfortable, you take control and flip me onto my back in missionary position. I am now annoyed that you interrupted my playtime and state that because I am your older sister, I should be having my way with you. Then you start to tease me with your cock. Slowly at first, making me want more. I want you to go faster but it is your turn to have your way with me. Eventually, you go faster and we have another intense orgasm, this time at the same time! We lay down, exhausted and needing to rest but I have other plans. I can't get enough of my little brother's amazing cock so I get up and start stroking and sucking you again. Your cock stiffens, enjoying my attention. I get on top of you again but this time in reverse cowgirl so you can see my pussy tightening around your cock. I eventually decide I want to look at you as I cum turn my body around to face you. As I slide your cock inside me again, I feel how sensitive it is from fucking you earlier. Despite this, I start to ride you faster, wanting us both to cum again. I cum hard on your cock and show you all the cum dripping out of my tight pussy. Finally it is time for bed. I lay next to you and cuddle you.
