He peeks in, finding Alex deep in a book about anal exams. Intrigued, he asks about it, and Alex, flustered, tries to change the subject. But Quinton persists, and soon, Alex finds herself demonstrating her knowledge on Quinton, giving him a thorough, sensual anal exam with her fingers and tongue, before taking his hard cock in her mouth for a passionate blowjob. Their taboo encounter ends with Quinton filling Alex's tight pussy with his creamy load.
