Almost Caught Fucking My New Gf at my Family Cook Out

My new girlfriend & I got invited to my family's lunch. I don't really bring girls around at all but I couldn't wait to show off. Little did I know, Eliana wore a dress that perfectly wrapped around her body and big tits. She made sure to send me a photo on the way to my house showing off the underwear she wasn't wearing under her skirt. Immediately, I was already rock hard and there was no way I could hide it in my khaki pants. By the time she got to my house, I couldn't keep my eyes off her and I wanted to fuck her. There was no way, there was family walking around everywhere. Yet, I couldn't stop thinking about it and she kept whispering in my ear how bad she wanted my cock inside her. We sneak around the back with a few minutes to spare, she slides her skirt up and I slide my cock deep inside of her tight wet pussy. Right before we go in, I make sure to fill her up with cum so she can walk around with cum dripping down her leg.
