Taking advantage of her nakedness

Mackenzie gasped in shock when she felt Michelle's hand squeeze one of her breasts and Katie stroking her pussy underwater! The naked girl's chest spasmed slightly since she was not expecting her friends to invade her personal space, let alone take advantage of her nudity. Her bare shoulders rose out of the water and her upper chest slightly revealed out of the water, showing a little bit of her cleavage. Michelle took notice of it and lifted one of her breasts out of the hot water and started massaging her soft nipple in the cold air, contrasting with the hot water, causing Mackenzie to softly moan.

"Looks like you weren't lying, Mackenzie," Katie giggled as she was working on Mackenzie's nether regions.

"Sh-shut up!" Mackenzie responded weakly.

"Who knew you would've come in here with nothing on? You're so naughty!" Katie teased. Mackenzie was surprised by that comment.

"I-I told you! I lost your gifts on the way! This wasn't intentional, you know!" Mackenzie snapped at her.

"Come on! Now how would you lose your outfit on the way here? Your story doesn't add up to us," Katie said as her hand began to slowly add more pressure and speed.

"I-It's a long story, but what I'm saying is the truth!" Mackenzie grunted. She gritted her teeth, trying to hide any of her potential moans.

"Well, if that is the truth. At least you didn't lose the Santa hat that I got you! Looks like that's the only one that survived her trip! I'm flattered! Haha!" Michelle laughed.

She was right, though. Out of all things that survived the trip, it was her stupid Santa Claus hat that sat right on top of her head, which practically covered nothing of her naked body. It annoyed Mackenzie just thinking about it! Not only did she realize that wardrobe malfunction, but she also realized how turned on she was during the whole trip until now! She didn't want to admit or show her arousal, but it wasn't easy when two of her friends were fondling her intimates. The hot water was also stimulating every inch of her peachy skin while she felt the winter air blow on her slender shoulders and one of her nipples that was starting to point out in an outgoing shape from all the tweaking from Michelle's soft fingers.

It felt nice. One of the things Mackenzie had never experienced in her life. But it was also embarrassing! Being fondled in a public hot tub! Can Mackenzie even go through with that?
