An girlfriend and i were making out. [I Love Cfnm]

I was in a pair of swim trunks. She had on shorts a t-shirt. She of course knew I was hard. She started to slide down the front of my swim trunks. I raised my butt and slid them down to my knees. We kissed some more. We stopped kissing she looked down at my erection. She took the tip of her thumb and started to rub this one spot. A very sensitive spot on my erection. It made my erection tense up and felt great. After about 5 minutes my breathing changed and my body tensed up and I pushed my hips up and started to cum and she kept rubbing just that one spot. After I was done we layed there for a bit longer before she got me some tissue to clean up with. Me still naked and her still clothed.
