Public Restroom Sex with Step-Sis

My stepsister and I have been engaging in secret activities for some time now. The fact that it's forbidden for us to engage in sexual activities with each other only adds to the excitement! Recently, we've been testing the limits to see how far we can go with our taboo encounters without getting caught. During a recent dinner outing with our new parents, things heated up.
While enjoying the appetizers, my stepsister provocatively ran her fingers up my leg towards my groin. I had to engage in a conversation with my stepmother about why I needed a math tutor, all while my stepsister was pleasuring me under the table. I was on the brink of climaxing all over her hands when the main course arrived, leaving me with a throbbing member and swollen with desire! While my stepsister found this situation amusing, I knew I had to find a way to release the tension soon.
When she excused herself to use the restroom after the main course, I seized the opportunity. In a rush to satisfy my longing, I surprised my stepsister in the public restroom while she was seated on the toilet. I locked the door, pulled down her pants, and engaged in passionate intercourse right there in the restaurant restroom.
To ensure she wouldn't get pregnant, I ejaculated into her willing mouth, and she gladly swallowed every drop. Dessert was truly served!.
