The Nude Beach

My girlfriend and I went to the beach yesterday. It was after a very hot session of sex between us. She marked on my butt "I (heart) ANAL) with magic marker, and my string bikini made it show. I was terribly embarrassed ,but she made me roll over at first and lay on my stomach. After a half hour, she inserted a j*weled buttplug in me in front of everyone. When I rolled over on my back, she wrote above my bikini bottom, just above my hairline "For Girls Only" and pulled my bottoms down a bit and drew and arrow down to my pussy.

She said it was so everyone would know we were together and that I was hers and hers only. I love her, I want to do whatever she wants but I was so embarrassed. I've never even kissed another girl in front of anyone, but yesterday she was full on making out with me on the beach.
