They kept whispering and giving me sideways glances so I think they knew I was watching. I turned away and checked that non of my family had noticed. ...hey were all talking and hadn't noticed. I turned and laid on my front with my head facing the 2 teens and my now hard cock pressing into my towel making a dent into the sand below. After about 10 minutes of looking at these 2 gorgeous teens with their tits out just 2 meters away from me I was fantasizing about cumming all over their hot. Lynn managed to push herself away but only so far, he still held her in place. He fixed her with a piercing stare, “who’s the master now?” he asked, he said it loudly. He was bringing her to another orgasm and you could see the shock on her face that he could do this so soon after her last one. Her eyes seemed to be searching his for something, she let out a moan. Her eyes were half closed as he asked her again “Who is your master slut?” she flinched again at that word. Her body answered as she. Her panties were wet at the crotch and there was slight bulge there also. She then said that as we had been walking up the road, she had turned on her small vibrator which she had positioned roughly at her clit. She been arousing herself as we had been walking up the road. When I heard this my cock was standing to attention, looking for some action. I quickly undress while she danced about the room, her body bouncing up and down still wearing the panties. As I lay back on the bed, Lisa turned. Queer bashing was quite popular back then. “Now, go push the door open and pretend like you just got here.”He did as I asked and walked to the usual place. I could hear the girls giggling in the bathroom. Derek knew who they were because he could hear them talking and laughing while he was in the backroom.Derek was fidgeting and seemed to have nothing to say. I looked at the clock. It had been 3 minutes or so since he pretended to get there. I let him off the hook and told him to come back.
