The next morning, Mythra said, "Wish me luck."

Pyra said, "Good luck, don't make the same mistake that I did."

Mythra offered to help Rex with a few errands today. Howver, the longer it went on, the smaller the resistance was until all of the errands were done, Mythra tried hard, but caved in like Pyra did.

Rex made breakfast before Mythra could even help, she offered to make lunch while floors also needed to be mopped. Mythra managed to keep nakedness spree going by borrowing and wearing only the same apron Pyra used yesterday and she spent enough time in it that she almost forgot she would be bare if the apron was removed. She would do most of her work, take off the apron, then hop on the couch and masturbate, only stopping and putting the apron back on when Rex walked into the same room as her.

Mythra was doing her deed on the couch after mopping the kitchen floor. She had opened the windows for a cross breeze to help dry the floor faster. When Rex asked for more help, she hurriedly came along without Rex seeing her touch herself, her breasts were bouncing under her apron.

After making lunch and doing the dishes, she began to spend the next few hours mopping. To keep herself going, Mythra relived her dream sequence in her head where she and Rex would get naked and fuck in public. However, Mythra gradually let her lust and and libido take over with her brain struggling to moderate the situation. She was now mopping the steps slowly while smiling, she did a quick check without being obvious to make sure she was still covered and tied in the back. The apron went down to her mid-thigh and wrapped partially around the sides, but the back and buttocks were completely open. Her nipples were subsiding a bit, but still barely pushing out the apron. Rex never realized that Mythra was naked underneath, she was teasing him as much as she could without simply giving in to her urges because the way Mythra moved about prevented Rex from seeing her exposed ass.

It was only a few minutes before the last chore was done, which was to mop the remaining floors, but the blonde was the on brink of losing control. Mythra was dangerously close to making the same mistake that Pyra did and ultimately could not resist any further, so she took off the apron and smiled, "Oh, Rexie."

"What?"

"I am completely nude, if I turn around and get it you will see my bare butt. Now, I want to expose myself to you."

Rex was confused, "First, Pyra. Now you?"

Mythra turned around to show her butt, she could feel his gaze on her ass. Rex then blurted out, "Who's next?"

"Probably Nia."

Nia poked her head out of Pyra's bedroom door and said, "I heard that and I resent your implication."

Mythra said, "Well, to be honest, I love being naked. Just like Pyra, I like letting people seeing me naked and even watching me masturbate, and I fantasize about us being watched having sex, it's a dream I want to come true. I've been resisting the urge all day, but I just have to do this."

The blonde walked towards Rex and kissed him on the lips. She slipped her hands under his pants, dropped them and got a hold the throbbing cock that was dripping with pre-cum. The strokes were a mere formality for Rex, Mythra was ready to cum. She took off Rex's shirt, gloves and shoes so he would be just as naked as her, then stuck his penis in her pussy, which was a little too much for the blonde, who pumped faster than Pyra and moaned, "I think I'm going to cum any second."

Rex assured her, "Don't hold it in if you don't think you can."

A few more thrusts, then Mythra let loose, she hastened her orgasm and came faster Pyra did. The first stream shot all the way up to her pussy. She pulled it out so the second stream covered her upper chest and neck while the third coated her stomach and the rest just dribbled out. Rex let out the words, "Wowie! Wow!"

Now reality was setting in. Rex offered, "Hang on I'll get you a napkin."

Rex darted up the kitchen and grabbed twenty napkins and brought them over to Mythra. His dry hand touched her cum sprinkled hand as he said, "Here you go."

She thanked him and started cleaning up, "You sure you are okay with this?"

"Yeah, I just need to go process this. I will probably have to go take care of myself as well."

Mythra was finishing cleaning up the cum she spilled in front of him. After Rex was out of sight, Mythra beat herself up, scolding herself as she said under her breath, "God dammit, Mythra. Why did you have to cave in? Why couldn't you just be resilient through those last few minutes?"

She sighed and told herself, "Sorry, Pyra."

Mythra joined Pyra and Nia back in her bedroom, all of them were still naked and Mythra was still looking disappointed in herself, even more than Pyra was last night, Nia knew exactly what her face was telling, "You failed too, huh? Strike two for us."

Pyra said, "Maybe we can convince Rex to go easy on us."

Nia remarked, "I won't have to, looks like it's up to me."
