Jerked off my son and accidentally fucked him

While her husband was away on business, mommy decided to share her bed with her son. Left alone with him, her son asked his mother to jerk him off before bed. While doing so, the mother became so aroused that she did not notice how her son began to caress her pussy and then fuck her with his fingers. Hearing his mother's characteristic loud moans, the son took it as a green light and decided to try his luck and stick it in her.
