Chas already had it in his head that if anyone said anything, he'd just say someone at school upset her or something so he's trying to cheer her up. "if anyone asks, I'm your uncle" he whispered to her, not that he thought anyone would ask. He walked inside the ice cream parlour, lifting her up onto the one of the stools in front of the 'bar' so she could see all the ice cream flavours. "choose what you want" he told her with a smile, as he looked for himself. 

Kay kissed him back as they slept together, moans escaping her as she kissed him, all whilst making sure not to wake Serena or alert Josh upstairs. But she was so wrapped up in her craving of John, it felt like they were in their own bubble, a bubble she didn't want to leave. Everything just felt so perfect to her in this heated moment with him, this was where she belonged...... 

--------A WHILE LATER--------

Kay, out of breath but content, laid beside John, the blanket now over them both. Smiling she laid her head on his shoulder, an arm over his chest.
