My stepsister kisses and gets fucked by her partner before their date

My step sister asked to fuck her before the first date. I was surprised but she explained that she wanted to make sure she could please her partner. After some intense kissing, she took out my dick and gave me a blowjob. Then, she climbed on top of me and rode my cock in cowgirl and reverse cowgirl positions, culminating in a creampie.
