MIL has my cock inches before her eyes accidentally.

Shortly before I got married for the first time, at only 22 years old, my girlfriend and I had a 2-level townhouse. At the time of this story, my girlfriend, at 20 years old, was about 8 1/2 months pregnant. Her mother, who lived in another state, decided to come stay with us until our child was born. Her and I didn't always get along so great. I really didn't have any issues with her, on the contrary, at only 44 years old, I found her pretty hot. Due to her daughter becoming pregnant by me and wanting to have our baby together, she sometimes spoke poorly of me. Before her arrival we agreed to leave any animosity we had before behind us and enjoy this amazing moment.
