She never knew such places existed and she was amazed by the whole scale of things. I was a bit, there must have been a couple of thousand people ther.... Jon had been there before so he knew his way round the place, but it had grown since he was last there.I really enjoyed sitting outside the cafés, eating and drinking whilst naked. Everything was just so ‘natural’.Early evening we left and walked back up the beach. We stopped at the car and had a bit of food and some wine. A number of other. She got tea and sat on the other sofa opposite me. We started chatting. I asked her about her education, school, college, etc and soon we went into a nonstop chat. As per my habit I was continuously looking into Mona’s eyes and also scanning her body. Her bra was visible from her top.Her hairs were set loose as usual. She was continuously speaking about her childhood and her school and college. Soon she noticed me staring at her boobs. She became slightly nervous and by this time finished her. My hands were on her shoulders rubbing the bra straps through the t-shirt. Abruptly she stopped and began to unbutton her shorts but then twisted herself round as she was tugging them down. "I'm having my period so you can fuck me in the ass," she said. This annoucement stunned me. I usually had to beg a girl to let me fuck her up the ass and was rarely granted, but here it was being willingly offered to me. I can only imagine the goofy smile that illuminate my face at that moment. "Do you. Mum, Vi, and I exchanged nervous glances."I don't think you'll be going anywhere tonight, Lilly dear," Mum said with a tired smile. "You'll have to stay. Adam can have the couch in the front room and you can bunk with Violet. It'll blow over by morning."I opened my mouth to argue but Mum 'shushed' me in much the same way she'd been doing since I was a kid. I'd learned early in life never to argue with my mother, but at times I still felt it didn't hurt to try.The back door blew open with a bang.
