We had sex that night, tender sex, but Sue was somewhere else, only going through the motions.As we got ready for work I watched Sue dress, she was pu...ting on a short skirt and a sleeveless top, no bra and high V cut French underwear, with her legs she didn't need to wear hose and opted not to. I asked her to raise the front of her skirt so I could see. She demurely raised the skirt just a little and exposed the thin strip of her underwear, showing she had trimmed her bush."Do you like?" Sue. ” She placed her palms on the floor and followed him. She was embarrassed, but as she felt herself blush she knew she was getting wet. She shuffled forward, her knees hot from the friction of running along the wooden floor, as he pulled her forward to the stairs. As he reached the bottom of the staircase he turned to face her, staring down at her as she peered up at him through her messy red hair. He didn’t smile as he unbuckled his belt, pulling out his thick cock, dropping his jeans to his. My wife and I gathered our towels andheaded for the springs, a small pool maybe 8 feet acrossand only 4 feet deep or so. We stripped off our clothesand jumped in the hot water naked, more than a littlehorny from the night before. We had just begun to kiss and fondle each other underthe water when my wife’s mother came walking up the pathwith a swimsuit on and a beach towel under her arm. Shelooked at us in the water, holding each other and said“go ahead, it’s not the first. She gave me a quick look from the distance.Again I was not sure what I should do but I decided to just go for it.I walked to the door and after a deep breath I pushed through to see her at the sink. Julia’s ass looked fantastic and I came up from behind pressing my hard cock against those firm round buttocks.My hands came up to squeeze her soft boobs from behind. Julia sighed in pleasure as she grinded her ass against my crotch.She whispered it was so bad; adding she had a wild fantasy about.
