I fucked my best friend’s sister

It was the end of our mid semesters. we were preparing fucking hard for mid term exams . After completing my second last exam (political science) . I had to rush to my tutions for studies as there was too much exam pressure . My tuition was approximately 1- 2 km away from our school . I had to walk all the way there because all the taxi drivers were on strike. After 30-45 min I reached my tutions .I sat on a table besides my friend’s .I suddenly heard an unfamiliar voice “yes sir , I understood what I have to do ”. She was my friend’s sister . She was newly appointed as a teacher in our tutions. No wonder I didn’t recognize her voice I was seeing her after ages .

I was 18 and she was 22. She was a bit health I’d say.She was wearing a sweat shirt and a decent jeans.Her shirt covered her upper body pretty well , getting a look at her clevage was impossible.but her breasts were so huge , it looked like they were gonna tear her shirt.Her ass was pretty impressive too. Just looking at her breasts gave me a boner .I had a hard time controling my pervertness.
