H...s dick rubbed against the sheer nylon panties, just itching to get underneath to the prize awaiting him. One hand pulled aside one edge of my panties and his dick slid under, now directly rubbing against my pussy. ‘Oh, God, I can't take it anymore.’ I was about to explode and have a pyrotechnic meltdown.

The kids enjoyed Papa and we all had a nice afternoon. Nicole wore a flowing sundress that she typically wore to church but I always thought it.
