The Retake Exam
Look, my teacher's pet. This is the body of your Mistress, the gift that waits at the end of the retake exam. If you pass it, of course.
Untie your testicles, pet. They've demostrated to be really tough and deserves a bit relief.
Your glans looks so hard and extremely sensitive. Start to stroke your cock slowly. Enjoy of my tight body. Imagine to rub my abdomen with your sensitive glans, imagine to slide your glans down, until touch my little pussy.
Imagine now to ram so rough your hard cock against my little pussy. Imagine the incredible feeling of your cock spreading my tight vagina. My wet inner meat will wrap really tight your cock, while you ram harder again and again.
Continue stroking slow, thinking on my body, until the edge. Then, stop.
