Marked Her Nips

My girlfriend is pretty submissive and though I'm not too experienced in having a woman like that I am really enjoying it. She is really pretty, hot body, nicely proportioned C cup titts that hang a bit, though she'd only 20. Her nips and the area around them are soft fleshy pink colored, almost the same color as her skin, so they don't stand out. I took brown india ink and colored them a medium brown color. They really stand out. I liked the color and my first fuck ever had that sort of brownish inner pussy lips, so I inked those too. I did that last wednesday night and we spent the afternoon today at the nude beach. She was really embarrassed by it but honestly there were women there with darker nips than hers. As she was there, she really gets off when I play with her and her lips swelled and her brown inner pussy lips were peeking out a bit too. I made her spread her legs out while sunning so people could see.

I'm kinda enjoying her being so sub to me. She likes a butt spanking too sometimes, in fact she will purposely do something I don't like, I think to get me to make her pull down her panties and raise her skirt to lay over my lap to get disciplined. I loved that she was so embarrassed by this. At the gym tomorrow I'm telling her she has to shower in the womens locker room, not come home to do it. I want plenty of people to see her brown nips and lips.
