Caught and fucked by stepbrother

I sit comfortably on the terrace and enjoy the peace and quiet. The sun's rays make me pretty horny and I start playing with my pussy. Gentle touches turn into fierce fingering. Suddenly I see my stepbrother watching me and wanking himself. What's wrong with you??? Well, now we're both horny and it's stupid to just break it off. So he should lick me first and then stick his bare cock in my wet pussy.
