I joined my boyfriend and his family in their weekend vacation at Subic. His family rode the van while my boyfriend and I rode in his car. Since it was just us in the car, my boyfriend was naughtily caressing my inner thighs and naturally, I got turned on. I took my panties off and that allowed his hand to freely finger me while he was driving. In turn, I was alternating a hand job and a playjob. Soon enough he came and I spat his come into a tissue paper and threw it in the wastebasket in the car. Upon reaching Subic, his dad looked for some receipts, and when he looked in the wastebasket, he got hold of the tissue filled with my boyfriend's come! I felt so ashamed when his dad winked at me as if saying he knew what had happened on the road. His dad kept on smiling at me the whole time. How embarrassing!
