That night I went to bed early with Kim, we were exhausted after a long working day. About 3am I wake up alarmed. I thought Kim was trying to wake me up but when I look better it's her step-sister, Alex, doing what I had always fantasized she would do. She was in her cute little pyjama smiling a wicked smile and telling me to be quiet. Then she lies her hand on my cock and starts caressing it, trying to make sure I wouldn't make a scandal. Of course I wasn't, I had wanted to fuck her since the first day. I start touching her soft body, equal but yet so different from Kim's, as if the taboo made it even softer. But wait, hide!! Kim is moving, she's gonna catch me cheating! Damn! Oh no, she's smiling at me, she thinks I'm masturbating and wants to help. God bless, Kim is sucking my cock now, I turn her around and fuck her beautiful pussy, Alex is hiding under the bed and now I really want to fuck both. Alex is waiting, touching her pussy to the sight of her step-sister and me fucking, she's so wet now and keeps sucking me. I have to fuck her! I get her naked and fuck her until she cums on my dick. Well, actually she fucks me, she's so determined. Now's she's sucking my cock and jerking me off double handed, I can't resist it anymore. I explode in her hands, filling them and her mouth with cum. Wish I could cuddle with both of them, but Alex leaves. I turn around and hug Kim. Breakfast will be awkward
