That meant that she had big tits. She looked almost as good as the women in my magazines and that got me to thinking about her when I jerked off.Howev...er, I realized that day that my little sister had tits too. They were small but they were growing. Dad always told Kate that her tits would be as big as her mother’s tits someday.Their bikinis were brand new because they had just gone shopping the day before and it was my first look at them in them. Mom’s bikini was bright orange and sexy. Her ass. We arrived at six in the morning and picked up our rental car and were off to the Marine Corps Air Station at Miramar. Miramar used to be a Naval Air Station and was famous for the Top Gun training but when the Navy moved that to Nevada the Marine Corps took over the base for the First Marine Air Wing headquarters. We arrived and were given spare rooms in the Bachelors Officers Quarters (BOQ), settled in our rooms and then went down to the flight line and found the maintenance hanger.That night. You’re my brother. We should go!”“Look, sis; like I said, we have seen each other’s bodies anyway. So what’s with the coyness? Are you saying that if I wasn’t here you would whip off that bikini and show all to those on this beach? You don’t know if the people here aren’t horny guys, lesbians, perverts, or more. But because I’m here you don’t want to bare all. Look, that sexy, tiny bikini shows off most of your horny body and hides very little anyway. It hardly covers your nipples and clit.. I instantly felt the twitching starting as it started to grow and get really hard. I could feel her breathing change she slid closer to me but never looked up from the tv. I slid my hand down to feel her upper thigh and found that the shorts she was wearing were now not up on her waist they were at her knees. She grabbed my hand and put it on her very heated pussy. She was so wet, the sene had ended but she kept her hand where it was and was taking her thumb across the tip of my cock. Every so.
