A couple of months ago my mom had one of her friends, called Pam, to stay overnight at our lakeside cabin. Although Pam is my mom's age around 35, she has a firm tight body and when I saw her sexy blue bikini I was instantly turned on. Pam had a small gold chain around her waist and an ankle bracelet too.
Pam talked to me while I swam by the dock and she lathered herself up with suntan lotion. When Pam was putting her lotion on she ran her hand under her top and I could see her beautiful firm breasts and even got a glimpse of her nipples. Pam did not seem to care if I was staring at her and she continued to rub lotion up and down her long sexy legs. As Pam laid on her stomach I pretended to swim around when I was really getting a good angle to stare at her ass. When she turned over I could see a couple of stray pubic hairs sticking out. They were black and curly and I got an instant hard-on.
Later that day Pam and mom were out on the front porch talking as I was watching TV in the cabin. I snuck into the bathroom and sure enough I found Pam's bikini bottoms. I pressed them to my nose and I was intoxicated when smelling her sweet pungent pussy in her bikini. I sat down on the toilet and began to jack-off while still smelling her panties and then I began to lick and suck her juices out of them.
To my suprise I heard Pam say, 'Well well, are you enjoying yourself?' and I looked up to see Pam standing in the bathroom doorway. I froze and Pam closed the door behind her. She smiled and told me it was really kind of a compliment that I was so turned on by sniffing her bikini. I begged her not to tell my mom and she told me if she could watch me masturbate to orgasm then she would not tell my mom.
I couldn't believe she was saying this but as I started to jack-off her eyes were glued to my rock hard cock. As she watched me I couldn't help but notice her nipples began to stick through her t-shirt and she was rubbing her twat through her shorts. She started talking to me and that put me over the top. As I told her I was getting ready to come she rubbed herself faster and came right in front of me. I began to come and the first stream of white cum splattered on her bare foot and the rest on the tile floor. Since she was watching me I seemed to come twice as hard and twice as much. She told me I had a beautiful cock and watching me come really turned her on. When I asked her if she came too she smiled and said yes she did. She asked me if I had ever helped a girl come by masturbating her and I told her no. She smiled devilishly and told me someday soon I would get the chance.
