I was relaxing in the hot tub, enjoying the peace and quiet that had been absent around the house for so long. Lisa was on a shopping trip to Chicago with her sisters and would be gone all weekend and her mom had finally moved back into her apartment after three months staying with us. Marge wasn't a bad guest, other than the fact that Lisa wouldn't have sex with her mom in the next bedroom. By the time Marge was ready to move back into her place, I was more than willing to help move her furniture. Helping her move had taken its toll on my back so I had taken the afternoon off work just to enjoy some peace and quiet and a good soak in the hot tub.
I slipped down into the water, enjoying the hot jets massaging my back. I had almost drifted off to sleep when I heard footsteps. The door opened, and I looked over my shoulder to see my mother in law standing there wide eyed. She was wearing a robe which hung open revealing a white swimsuit, her tits barely contained, and her pubic hair poking out on either side of the small white bottoms.
"Oh, I'm sorry Mark." she said, "Lisa said you'd be working until late, and said I could come over and use the hot tub."
"Oh, uhm, I took the afternoon off." I said, as I sat more upright trying to conceal my nakedness. "I'll be out in a minute."
"You don't have to get out. I'd like the company." she said, hanging her robe on a hook and walking over to the hot tub.
"But, uhm." I started, as she turned and climbed into the tub, stopping suddenly as her eyes locked onto my nakedness.
Her eyes went wide, as she saw my hands covering my crotch. Her face turned red, and she just stood there.
"Oh, I'm, uhm,, I'm sorry. I wasn't thinking." she said as she grasped the edge and started to step out.
"Sorry." I muttered, "I tried to warn you. I hate wearing a suit in the hot tub."
"This is, uhm awkward." she said, her eyes locked on my crotch.
"Well, you might as well get in." I said, forcing a smile.
"You sure. I mean, it's ..."
"Well, it's too late anyway. You've already seen what there is to see. Might as well just sit down and relax." I said, finding myself staring at her near nakedness.
"It's a bit cozy though, so watch where you put your feet." I added with a chuckle.
"Smart ass." she said, smiling as she stepped into the tub and slowly sank down into the water.
"So, you all unpacked." I said, trying to make small talk to distract myself. The water had turned the bikini nearly transparent.
"Mostly, which is why I'm here. Some of those boxes were pretty heavy. Which reminds me, I want to thank you for letting me stay with you guys. I know it wasn't ..."
"No problem. It was nice having home cooked meals for a change."
She noticed me staring, and looked down at her top. Her hands immediately went to cover her breasts as she realized how see through it had become.
"That's Lisa's suit." I said, smiling.
"Yeah, she gave it to me, said she never wears it."
"Well, now you know why." I said, chuckling.
She smiled, and shifted around, her legs bent at the knees to avoid coming into contact with me. Like I said, it was a two person hot tub, and there really wasn't a lot of extra room.
"You might as well relax." I said, placing my legs out on either side of hers. "The hot water won't do much good if you stay all crunched up. And I promise to stare only a little bit."
"Your not funny." she said, trying to sound mad, but there was a smile on her face.
She blushed as she slowly extended her legs between mine and slid down into the water. As she began to relax, her feet began floating about, shifted by the jets of water. Every time they brushed against mine she would jump.
"I'm sorry." she finally said, sitting upright. "I just can't seem to relax like this. It's just, I mean..."
"I know what you mean. That's why I don't wear anything in the tub. Clothes just seem to make it hard to relax."
