So after the show we put on for the security guard the night before, the word obviously got round amongst his colleagues. We had spent the day on the beach, my gorgeous exhibitionist slut of a girlfriend winding me up at every opportunity, standing up topless and fixing her hair, pushing her massive silicone tits out for the benefit of all the guys sat around with lazy hard ons, bending over with her thong up the crack of her arse whilst all around licked their dry cracked lips. We got back to the apartment around 4ish for a quick fuck and a kip and woke around 6ish.She went off for a shower whilst I pulled on my cock for a bit, when she came back she was naked apart from a towel around her head, her new white bits clearly showing off her freshly shaved brazilian.It was my turn for the bathroom as she set about drying her hair. When I came out of the shower she was sitting at the dressing table still naked with the hair dryer blasting out. We were on the ground floor with a patio garden out front, as I glanced at the patio window I caught sight of a figure hidden in the bushes looking thro our window at my naked girlfriends body. I froze for a moment and felt my heart skip a beat. Should I shut the curtains and deprive him of a beautiful sight or let him drink in the view a little longer. I decided to let him carry on watching and as I walked past the window in front of him I felt my cock twitch and start to stiffen.I went over to my g/f and kissed her shoulders, she turned and exposed her breasts to the watcher at the window and gave my cock a playful tug. When she had finished her hair she stood up and started applying moisturiser all over her naked body. It was getting to twilight outside and I could see the bush was still occupied as she applied cream all over her tits and arse.She put her foot on the bed and bent over legs apart right in front of the window as she did her feet in turn. What a view he must have had, I smiled to myself as my cock stiffened to its full erect glory, so I walked over cock swaying from side to side, took the bottle from her and filled my palm with moisturiser. I started to apply the cream to her back and shoulders and eased my cock into the crack of her arse as I did. I then pushed her on to the bed, our backs to the window and eased her legs apart displaying her cunt and arsehole to the watcher as I carried on greasing her body. Her cunt was damp and oily, and my cock which was oiled up from her touching her arse was gliding up and down her crack probing her openings. I started to ease the tip into her cunt which by now was glistening and swollen. My excitment was enhanced knowing we were being closely watched. I pulled out of her and turned her round so that Tom could see her big tits hanging down and swinging as she knelt on the bed. I stroked my cock in front of her face, which she loves and pushed it into her mouth and she took hold of it and began wanking and sucking it hungrily. I thought it was a good time to tell her about our friend, she nearly choked on my cock which was deep inside her mouth and she turned to look at the window.He had moved closer and his face was clearly visible against the glass, the cheeky bastard. What a nerve I thought, he didnt flinch. I said to her, shall we invite him in or carry on teasing him. Ever the filth slut, she said bring him in, with her mouth full of cock. So I went and slid open the patio door about a foot and said nothing to him thinking I would let him make a move. I went back to my g/f who was lying on her back on the bed with her legs open. I mounted her and slid my cock up to the hilt of her juicy wet cunt and began to fuck her with long lengths. Our watcher bravely stepped into our room and sat on the stool and said nothing but just watched us fucking, I was nervous but so turned on by how close he was.He was about 20 with dark curly hair and I was then aware of him removing his jeans and stroking his already hard cock. We all just watched each other but said nothing. His cock was impressive with a shiny purple end and he began to wank it slowly. I continued to fuck her sopping cunt, I could tell she was coming on my cock but managed to keep it quiet. Our new friend stood up his huge erection standing up better than mine ever did and came to the bed. He knelt on the edge and pushed his cock towards us, I could see pre-cum on its tip and for some reason I couldnt help, I put my tongue out and licked the juice from his cock. My girlfriend cried out loudly as she had a massive orgasm. (she later told me she used to fantasize about me sucking cock). This brought me to the edge and I felt my cum begin to rise, I pulled out of her cunt and began to wank off over her tits and face, my cum exploding out of me as it shot in ribbons over her soft tanned skin. At this point our guest also began to cum, his spunk fying all over her tits and stomach. The spell was broken as we all had cum and he quickly pulled up his jeans and left without a word. We continue to go back to the same apartments in the hope for a repeat performance and we shall be there for a long weekend in April looking for some more action.
