We have a vacation home in the mountains which has a beautiful hot tub overlooking the valley and surrounding mountains, in a landscaped area just off of the patio in the back. We always have visitors to the home since it is near a large ski area, and is also a great gathering place for our out of state relatives. We often have friends over and many times people want to sit in the hot tub sipping wine and enjoying the views. My wife keeps a couple of once piece bathing suits on hand just in case someone want to use one and is too shy to go au natural. The first Thanksgiving up at the home, my MIL decided to join my wife and I in the hot tube one evening, and naturally my wife gave her one of the swim suits to borrow since she had neglected to bring one. My wife had found a plain inexpensive white one piece swimsuit to which she keeps on hand, as well as a couple of others in different sizes, and gave it to her mother. When her mother came out of the guest room she had her towel wrapped around her and followed us out to the hot tub. My MIL has large heavy breasts which I noticed, were tightly encased in the thin white material of the swimsuit as she hung up her towel and entered the water with my wife and I. We all sank down low in the water, enjoying the warm water bubbling up from underneath as we sipped our wine and talked. My wife gets hot easily and it wasnt very long before she said that she was sufficiently relaxed, excused herself and headed inside. My MIL continued to chat and stayed out a little longer. Commenting that I looked like I needed more wine, my MIL took my glass, and said that she would return shortly with refills for both of us. When she began to exit the water, I noticed that the thin white material of her swimsuit, had grown nearly transparent when it got wet, and due to the inexpensiveness of the swimsuit, it obviously wasnt lined, and I had a perfect view of her silver dollar sized nipples, as well as her thick black pubic bush. She quickly grabbed her towel and headed into the house. I was sure that she would holler out that she was staying in since her suit was completely revealing, but to my excitement, she returned shortly with another glass of wine for each of us. I quickly hopped back down into the water since the sight I had just seen caused me to nearly tear a hole in my swimsuit, and there was not way that I could hide the bulge! I am still not sure if my MIL was completely oblivious, or if she was teasing me, but a few minutes after returning and sitting in the water, she said that she was getting hot and rose from the water and sat on one of the seats positioned on the edge of the hot tub! Her nipples looked like they would tear through the spandex material of her swimsuit as they hardened against the cold mountain air. My eyes kept darting from her hard nipples and large aerolas, to her thick curly black muff barely concealed by the crotch of her swimsuit, which was at eye level as she sat on the side of the hot tub! My cock was throbbing looking at her curvy womanly body, and it was all that I could do not to start stroking myself under the water! Thankfully after another 5 minutes or so we decided to head inside for the night. Because we were in the mountains during the winter, exiting the hot tub can be a little icy and slick so as my MIL began to climb out I followed closely behind in case she slipped. Just as she was about to climb out she abruptly stopped before starting up the first step, which caused my hard tent pitching cock to bump into her bottom! She said nothing about it but clearly noticed it as she began to help me put the hot tub lid down. Because it was so cold, I told her to head on in and I would finish outside securing the lid. I did ask her if she would turn on the timer for the dry sauna just inside the door, so that I could warm up again once I was safely back inside. When I got inside I wrapped the towel around my waist dropped my wet boardshorts, hanging them on the hook in the bathroom, and walked across the hall to the sauna which my MIL had turned on for me. It was late at this point, I was terribly horny, and the house was dark and quiet, so once inside the sauna, I dimmed the light a little, folded my towel for a comfortable cushion to sit on, and sat nude enjoying the penetrating heat. I could feel my cock hanging heavily now as I planned on heading up to our master bedroom and sliding into my wife as soon as I sufficiently warmed up in the sauna. I sat there with my eyes closed relaxing when all the sudden the sound of the sauna door opening nearly had me jumping out of my skin!
