Julie was in front of me, pressed up to the window, engrossed in what was happening. I wasn't sure if she would react and maybe go into the room to he...p out the girl in trouble. She was off duty but still their teacher. She didn't move so I pressed up behind her for a better look. The ringleader was a girl called Sarah. She was a final year student and was hugely popular with everyone, teachers and students, and her popularity meant she was the also the 'Head Girl'. She was also red-hot.. .something else. Some of them surreptitiously adjusted theirtrousers.Even the professor seemed stunned. He was the one to recover first."Yes, it is. Do come in," he said with a friendly smile and she walkedin."Is this seat taken?" she asked when she reached Britney. "No, it'sfree," Britney replied with a smile.

Once clean, she turned her attention to Jackie’s pussy, going down on her and licking our juices out of her noisily. “I love it when you do that” Jackie said, and at that moment I realised these two were already lovers.Watching Sam lick Jackie’s pussy soon got me hard again, which Sam was not slow in noticing. “My turn now”, she said “fuck me doggy style!” It wasn’t a request, it was an order. I didn’t need to be told twice. I knelt behind her, and spread her bum cheeks with my hands, opening. While she ran home to get her bikini, I got into mine. Too say the least, I was pretty excited as I undressed and deeply regretted my husband no being home. Anne was back in no time wearing a knee-length jacket over what I presumed to be her only in bikini-clad body underneath it. I was standing in the warmth of the sun room with just my bikini on. “Wow, Jannika, you are one sexy lady” she exclaimed as her eyes ran up and down my body. It felt nice to have her admiring my body and paying.
