I was eating out my girlfriend -25 - as we were staying the weekend at her mom's place, keeping an eye on the place while her mom was gone. As you tend to do, we lost track of time - so we forgot about her mom arriving home. I made her come as I gave her oral, and being super horny, I told her to roll over and began banging her from behind lying prone. I pumped away for a good 20 minutes, mumbling dirty talk to her and smacking her asscheeks before busting a huge load over her ass. Imagine my feeling as I go to grab water, out of breath and my girlfriend's mom sits there with a huge grin.

She smiled and said "you seem to take good care of her" and chuckled softly.

I wanted to die.
