Penny goes too far

After applying sunscreen to their front halves, which Briana was insistent on until Penny gave in, the two laid out on the beach blanket on their backs before Penny rolled onto her side with a hand on her hip, head on her hand, and a flirtatious grin on her face as she fluttered her eyes at Briana.

"So, what'll it be first, Cutie?" Penny asked, "Sun or surf?"

A part of Briana was surprised that Penny hadn't said "sex" as an option, but nonetheless she thought about her two options. Sunbathing seemed like it was the safest of two. However, she had a tendency to doze off when she got too comfortable. And knowing Penny, that would give the petite girl more than enough time to peek down the front of her trunks at best, or pull them down to her ankles and exposing her at worse! Swimming didn't exactly sound like the best option, but at least she could be awake enough to keep an eye on the girl and her never-ending quest to strip Briana of her trunks.

"I... Guess we can go swimming." Briana weakly suggested.

"Fine by me." Penny said as she jumped to her feet, helping "Brian" to "his" feet afterwards. "Lead the way, Cutie!"

Penny playfully punctuated that last part with another slap to "Brian's" plump ass, causing Briana to jump and turn to the other girl.

"Stop that!" Briana said as Penny giggled, once again trying to sound assertive, but coming off as sounding like harmless flirtation.

Briana and Penny walked down towards the water, walking past beach goers in various states of undress as they came to the shoreline. Briana blushed as she heard a few women giggle and whisper to one another as they eyed her walking by, unsure if they knew she was "Briana" and were laughing at her nonexistent breasts, or thought she was "Brian" and found "him" to be attractive.

Whatever the case, Briana's face was crimson by the time she and Penny got to the edge of the water, the surf tickling their toes.

"Last one in is a rotten egg!" Penny said playfully as she gently pushed Briana, racing towards the water.

Not wanting to draw attention to herself, Briana briskly jogged towards the water, keeping up with Penny as they waded into the surf until they were waist deep. Wanting to act natural, but still keep an eye on Penny, Briana closed her eyes and held her breath as she dove under the water and swam out to a large rock a few feet away. Briana was always a good swimmer, the fastest member of her college swim team even.

Unfortunately, Briana had not taken into account an important detail about her option to go swimming. Even tied as tightly as she could, the trunks were still relatively baggy on her. And this, combined with the angle she dove in at and her speedy swimming, led to one outcome.

Briana had swam right out of her trunks!

Penny had been stretching for a bit when she looked down, a familiar pair of swim trunks floating to the surface of the water. She practically drooled and her eyes became hearts as she noticed "Brian's" cute, plump, pale ass dart by under the water before disappearing from her sight. The petite girl then cutely giggled as she grabbed the swim trunks and playfully hid them behind her back as "Brian" emerged by the rock, her heart fluttering as she saw the top of "his" ass briefly break the surface before sinking beneath the waves again.

Briana briefly wiped her wet hair out of her face as she leaned up against a rock. However, her eyes widened in surprise as she felt the rough texture of the rock brush against the bare skin of her butt. It almost felt like...

"Lose something, Cutie?"

Looking up, Briana felt her blood run cold as she saw Penny smiling playfully at her, giggling as she held up...

Oh no.

Looking down, Briana went scarlet as she saw her own shaved womanhood under the clear water, letting out a squeak as she cupped it with both her hands. She was naked!

"Penny! Please!" Briana begged in a whisper, staring into the petite woman's eyes pleadingly. "Give those back! We had a deal, remember?"

"I do remember, but I didn't pull them off." Penny replied, twirling the trunks on her finger. "You swam out of them."

"Well then give them back!"

"Hmmm..." Penny said, pretending to think it over as she eyed the trunks in her hands. She then looked up with a playful grin and said, "If you want them, they'll be waiting for you on the blanket."

Briana felt her stomach drop as she saw Penny turn and slowly wade back towards the beach with her trunks in hand. Penny was actually expecting her to follow her on to the beach naked. There was no way she could pull off being a guy in front of everyone naked! Not even a guy with a small manhood like Stacy had implied she was. However, she knew that she couldn't stay out here in the water forever, either. A swimmer would eventually come across her, or worse: Someone would see her out here in distress and either investigate or send a lifeguard out to 'save' her. Either way, her secret would be exposed!

The humiliation of it all overwhelmed her. She couldn't take it anymore!

Penny had just taken a few steps forward when she heard a small sound from behind her, looking over her shoulder with a confused expression as she saw "Brian" silently crying, "his" face redder than any shade found before in nature before turning away. Penny turned around, feeling a mixture of heart break and confusion. This didn't make sense! When she tried this with JaMarcus back when they started dating and he lost his trunks, JaMarcus had practically scooped her up in his arms and carried her into her house, the two having the night of their lives.

And here she was, doing the same thing to "Brian" with the intention of giving "him" a taste of the best two weeks of "his" life, and "he" was crying in embarrassment. What was going on?

Suddenly, a thought came to her. Was her playful teasing coming off as mockery? She remembered how defensive and embarrassed "Brian" got when Stacy brought up his...

Oh...

Oh.

Oh no.

A look of horror came to her face as she brought a hand to her mouth, tears of her own welling in her eyes. No wonder "Brian" was **** to keep "his" trunks on! "He" must have been so self-conscious about "his" size.

And she just went and made this cute, sweet, and sensitive "guy" embarrassed to the point of crying! What had she done?!

Without a second thought, Penny raced towards "Brian", unknowingly dropping the swim trunks into the surf as they floated away.

Briana was sobbing quietly, unable to take the humiliation, as she felt a pair of arms wrap themselves around her tightly and a pair of breasts press against her back. She was just about to tell Penny to get off of her...

When she heard the other woman softly crying as well.
