Custom vid (no names used). You're lying in bed late at night when you hear a knock on your bedroom door. Your cute little stepsister comes in complaining that she's cold, and asks if she can lay with you tonight. At first you refuse, but she assures you that mom and dad are already down for the night. You see that she's scantily dressed in just a low cut t-shirt and satin panties (no wonder she's cold), but you certainly don't mind. She happily climbs into your bed and thanks you for letting her join you with a sweet kiss. She snuggles up against your warm body and gives you a few more soft kisses on your neck, gradually becoming more passionate. She notices your boner pressing up against her leg and starts caressing it softly. "Hmm, I think I have an idea of how we can both get warm and have sweet dreams tonight," she whispers with a smile. "We just have to make sure to stay really quiet so we don't wake our parents." She takes off your boxers and starts sucking on your hard cock, stripping off her t-shirt and panties along the way. You love the way she looks up into your eyes and talks dirty to you about how much she loves sucking her stepbrother's dick, and how wet her pussy is getting. When neither of you can take the teasing any longer, she tells you to get on top and fuck her in missionary position. You slide your cock deep inside her tight wet pussy and start fucking her nice and slow. You're both a little nervous yet excited at the possibility of getting caught, as it becomes harder and harder to hold back your moans. Your sexy stepsister puts her legs up on your shoulders so you can fuck her even harder and deeper, and it doesn't take long for her to cum all over your cock. But even after an intense orgasm, she still wants more! She tells you to get off so she can ride you in cowgirl position, since she knows it's your favourite. She slowly lowers herself all the way down on your cock and starts riding you expertly. She leans down to kiss you passionately and whisper plenty of naughty taboo things into your ear as she rides you harder and faster. When you start to get close, you warn her to stop before you cum inside her, but she just keeps going. With a smile, she says that she wants to keep riding you until you cum deep inside her. With those words and her pussy milking your cock, you can't hold back any longer and you both cum hard at the same time. After calming down a bit, you both cuddle up in bed again, feeling warm, relaxed, and ready for a good night's rest.
