Alex does.

Alex snorted. "Ugh! This is so gross!" Alex stepped aside, shimmying out of her shorts. "Nature is a much better bathroom." Alex stood completely nude, fuzz covering her pussy lips, the only hair on her body.

Alex stood with her hands on her hips, much like her character, Angel the Barbarian. Her pussy widened as she pushed back on her hips, posing for the four.

"The real way to pee is to do it on the go! Let's show Mia how it's done, shall we?" Alex asked, smiling at Nate.

She suddenly bent down in a runners stance, bare asshole poking directly at Nate and Mia.

Nate laughed. "You're so silly, Alex. You don't have to..." Nate's voice trailed off when he saw Alex take off in a sprint, her naked butt swaying back and forth. Alex took a sharp turn, running towards the edge of the building. Nate stood there, completely dumbfounded as Alex sped past him.

Nate could see Alex spraying piss as she ran through the field, her pussy gushing with urine. Alex ran faster, her breasts bouncing wildly. Nate's mouth dropped open when he saw the thick stream of urine flying from between Alex's legs.

Olivia and Mia were laughing. Olivia couldn't believe it.

Alex turned around and started walking back. "Okay, Nate, I'm back. Ready to finish this game now?"

Delilah didn't need to go to the bathroom, but she stood there naked. Her sister Mary had stolen her panties that morning after all. Delilah had a lot larger pubic bush than the other girls had, most likely due to her innocent upbringing. Her labia was darker, more brown, with a little pink mixed in.

Mia was still standing in the same spot as Nate. Her gym shorts were still on, untouched, as she watched the others relieve themselves. Mia was still standing there when Nate called out to her.

Nate had taken a seat on the ground, his cock sticking straight up in the air. "I have a confession to make, Mia. This isn't the only time I've ever gone to the bathroom in front of another person."

Nate reached for Mia, pulling her close. His hands rested on her hips, her ass. "You can sit here if you like, but be careful. If someone sees us, they might report it."

Alex sat on the ground, and leaned back against a tree. Olivia was sitting on a bench a short distance away, and Delilah was hiding behind some trees. They all were still nude, shorts and panties lying on the ground.

Mia sat on Nate's lap, his cock pressing against her left butt cheek. Nate's hands roamed Mia's body, caressing her back and sides.

Nate could feel Mia tense up when Nate's hands started moving. Nate's hands moved over Mia's back, cupping her butt cheeks. He started lowering her gym shorts.

Nate pulled Mia's shorts down to her knees, exposing her bare pussy. Nate's cock rubbed against Mia's thigh.

Olivia laughed. "Oh, you two are going at it again!" Olivia said, laughing.

Mia was blushing. "What do you mean?"

Nate and Olivia exchanged a glance. Nate's face turned red, while Olivia's turned confused. "Why... Why did I say that..."

Nate quickly regained tempo, putting his hand on Mia's stomach. Nate could hear Mia's heart beating rapidly, his own racing at the same speed.

"I'm going to massage your bladder for you, Mia." Nate began to press on Mia's belly, massaging her muscles with one hand, and holding her bare pussy in the other.

His fingers made their way past her clitoris, and directly to her urinary tract. Nate's finger rubbed the entrance of Mia's urethra, feeling the tightness of her hole. "This feels weird, Nate. I'm not sure if it'll work..." Mia's voice trailed off. Her eyes darted around, looking everywhere but Nate.

Mia grabbed Nate's cock without really realizing. She squeezed it in rhythm to his massage, his cock slowly leaking precum.

Alex walked up, seeing that Mia had her hands on Nate's cock. Alex giggled when she saw Mia masturbating Nate with her free hand.

The massage sped up as Nate knew Mia was nearly ready to piss herself. His hands were now firmly gripping Mia's stomach as he kept rubbing her.

Alex leaned in and whispered to Mia. "Your turn, Mia."

Mia's dam had burst when Alex spoke, urine spraying out of Mia's pee slit, soaking both her hands, Nate's leg, and the bench.

Alex laughed. "Looks like we're all done."

Alex took a step back, giving Delilah a clear view. Delilah gasped at what she was seeing. Nate had cum at the same time, coating Mia's hand and stomach with it. Delilah's mouth dropped open when she saw Nate's dick squirt.

Delilah didn't have to ask why. Delilah could see Mia's naked body, covered in Nate's cum. Mia's eyes were glazed over, staring blankly ahead.

Mia stood up, her knees slightly bent, still clutching Nate's cock. Nate smiled at Mia, and she blushed. Mia tried to stand, but stumbled. Olivia caught Mia, helping support her weight. Mia let out a sigh of relief.

Mia turned to Nate. "I can walk by myself. Thank you for helping me."

Nate's face flushed red. "No problem. We should do this again sometime."

Nate turned away from Mia, walking towards the pile of clothes on the ground. Mia watched him, then Olivia, and finally Alex.
