This year my mom hosted a big reunion party. I never expected what would happen! I came back into town from college and Mom's best friend, Helena was staying with us. I always knew she was attractive, but this year wow, she gets hotter every year! I really got a good look at her laying out in the sun before everyone was to arrive. She looked literally edible in her thong swimsuit; didn't she realize she was making me hard out there with all that ass in the sun and some of her bush peeking out of her thong? After we went in, i 'accidentally' walked in on her as she was getting done showering. I did my business while peeking at her and i ever caught her peeking at me! I got so hard in there with her and i was really grateful that she was able to give me a helping hand so we could get out there before anyone noticed. I really didn't mean to, but i blew my load so hard, it got all in her face and hair; it was really hot watching her look at me in shock after i surprised her by painting her up!
