I fucking love hand jobs and my wife’s sister loves giving them

My wife’s sister and family was over for dinner the other day and we were all around the table. My wife was serving the food. I sat next to her hot ass sister who just graduated college. She’s always been a slut but ever since she left college she’s been even more of a whore. She was wearing a short skirt and a sports bra. My wife called her mom into the kitchen to help, and her dad was in the bathroom. Her sister reached over and pulled my cock out of my Shorts and started stroking it. She spit into her hand and tugged in me for like 5 mins. When everyone returned she dropped it under the table cloth. Thought the night and dinner is feel her grab it, or watch her spit into her hand then she would run the tip around. I had blue balls for 2 hours till she left and then I fucked my wide thinking about her
