Beach Maturbation

A Couple years ago I went to the beach with my buddy his GF and her friend. The friend is way hot. We were laying there and she began putting oil on and needless to say I started getting hard so I rolled onto my stomach. She must've noticed cause she asked why I rolled over. I turned red and she said did I get you hard? I didn't say anything. My friends GF told her to leave me alone. She didn't. She asked me if I needed to jerk off I said yea but not here. She then said flip over let me see, I heard you were pretty big ( I use to date her friend frankly I think I'm average size but I'd love ur opinion based on my pictures and videos) I flipped over for a second and I was hard as a rock it was pointing straight up in my bathing suit it looked like a tent. She then said its never going to go down until u finish it off. She gave me the lotion and said do it here just put your towel over it I said no way ill get arrested. My hornyness kicked in so I suggested we go to the car. She said no way, if my BF finds out he'll kill us both. I said don't be a cock tease. She said she isn't a tease I told her to do it then incredibly she agreed. So now my problem was how to get to the car with a raging hard on. I threw on my t shirt adjusted my cock so it was pointing up and tucked into the waste band of my bathing suit. As the waste band squeezed against it a small amount of pre cum dribbled out. As we were walking to the car I said your going to help right? She said umm no, I'm not cheating on my bf. I asked if she would at least watch. She said no, I'm going to be your lookout. All I knew was I needed to cum. I gave her tge keys and she drove to a more secluded spot. I was sitting in the back seat. I asked for the lotion she said she didn't have it I told her I need lube she said just spit on it. I asked her if I could see her tits I've always wanted to see her tits she was petite about 5'4" and weighed 110 ish she had a big b or maybe a c cup. She said no. She said well get to work. I pulled my shorts down and spit on it like she said. I was stroking for a minute and neither she or I said anything she just played with the radio . She then asked how long is this going to take? I said I don't know spit isn't as good as lotion she said spit on it again. I did and then she turned around pulled her tits out of her bikini and within another 3 or 4 tugs on my cock I began to cum. This was one of the most memorable cumshots of my life. I guess the excitement of someone looking at me while jerking off caused it. 2-3 spurts shot up over and onto my left shoulder the remaining squirts onto my chest and stomach in the midst of my cumming she said holy shit when was the last time u came? I didn't answer until I finished. I don't remember what I said but I'm sure it was only a few days. My shirt had cum all over it so I wiped myself up with the shirt and we headed back to the beach. She begged me not to tell anyone. I just told a few other friends and our friends at the beach knew. Word never got back to her BF. She ended up marrying him and has a k**. That was one of the best masturbation sessions I ever had eventhough the act itself lasted only a minute or two.
