Then she turned to face him with one cheek on the bench seatand her back to Debbie, she could feel the butt plug inside her, and hercock was straining... inside the chastity device. It had spikes on theinside so any form of erection was extremely painful as soon as hismember came into contact with them.She brought her lips right up close to his, without kissing him, and nowshe was confident that no-one could see her hands under the table, sheunzipped him and slipped her hand inside his trousers..

She was moaning as we licked and sucked on her. Cassie’s little bump peeked out eagerly from her inner labia.
