Incestuous camping trip with a young stepsister on a national holiday

It's a national holiday and you decide to spend some quality time with your hot step sister. You pack up the car and head out to the great outdoors for a camping trip. The plan is to set up camp by the river and spend the day swimming and having fun. As you arrive at the campsite, your step sister offers to help you set up the tent. In the process, she accidentally brushes against your hard cock, making you both a little flustered. To break the awkward silence, you suggest going for a swim in the river. Your step sister eagerly agrees and strips down to her bikini. As you dive into the cool water, she playfully rides you, straddling you in the cowgirl position. The water adds an extra layer of excitement to the encounter, making it even more intense. After your dip in the river, you both return to the campsite, where the real action begins. Your step sister eagerly gives you a blowjob, before riding you hard in various positions. The outdoor setting adds an extra thrill to the already taboo encounter.
