After doing well in college, my stepson receives a special reward from me

After acing his college exams, my stepson found himself in a rather unexpected situation. I, being his stepmother, decided to reward him in a rather unconventional way. I led him upstairs to my room, where I began to undress him, revealing his youthful body. As a big-assed brunette, I couldn't resist the allure of his tight, young ass. I proceeded to tease him with my big cock, causing his own little soldier to stand at attention. I then took him from behind, fucking him hard and deep. The sight of my big cock disappearing into his tight hole was enough to make me cum all over his back. But the pleasure was just beginning. I then had him kneel down to receive my cumshot, his cute face covered in my hot load. This was a special reward indeed, one that both of us would remember for a long time.
