My High School biology teacher Pt. 3 Birthday sleepover. [lingerie], [oral], [riding cowgirl] [FM]

**I previously posted parts 1 and 2 of ‘My high school biology teacher’ a couple of weeks ago. I’m now using a new account just for the purpose of posting these stories about a long, glorious summer I spent fucking my high school biology teacher (Mr. B). He was amazing and the first man I loved. This is the account of our first sleepover at his house on his 43rd birthday, my first time wearing lingerie and the first time I rode a man like a wild animal… Embellished for artistic license but all events and general conversations are real.. enjoy!**

After our first encounter (parts 1 and 2), I had been back to Mr.B’s house many more times, always after school had ended and he was settled for the evening; typically around 7pm. I would arrive, we kissed, then he would work on his marking and lesson plan while I perused his large book collection, watched tv, or sat in his lap waiting patiently for him to turn his attention to me. I was still his good little student, even though I was now 18, exams were over and I had technically left school. He asked me questions about biology from his lesson plans and I loved watching him work. I was spending one of these evenings at his home with him in the middle of June…
