Gf grinding in front of my family

We were having a family BBQ one summer with my gf at the time, petite Latina about 5’1” bubble butt and D cups. Honestly a perfect fuck doll. We were sitting around the fire, she’s sitting on my lap. Being the horn dog I am I started to bulge beneath her. The more I grew the more she playfully turned as she talked to people. After a solid 15 minutes of her subtly grinding her ass on my dick in our family circle, my younger cousins rant through spraying everyone with super soakers. Everyone got soaked, except myself using my gf incidentally as a shield, and my grandmother cause my cousins new better. With everyone soaked, their parents got up to reprimand them, while my gf got up to get a change of shirt not wanting to basically be in a wet t-shirt competition at a family BBQ…leaving me hard af in front of my grandmother 🤦‍♂️
