Later in the afternoon (Tina's Pov)

-Cheese!-.

The sun is setting behind you, and you are taking your last selfies while sitting on the grass. The field around you is calm, but not completely silent. The noise of the branches is accompanied by the sensation of a cool breeze on the skin, and your silly giggles often soothe the air. Sometimes you see bikers coming down the road below you, and young and old taking a walk before dinner. To their eyes, you're just a couple of jovial, cute girls enjoying their time outdoors.

-Ok, now make a funny face! Ahah, here! How is it?-.

You lean your cheeks on each other to see the cell phone screen. For a moment you even don't realize it, actually feeling the friendship bond between you. But then the warmth of her thin layer of sweat, her smell on your nostrils, her soft bunned hair rested over your ear, they all rekindle a different emotion in you. You look at her, she looks at you, your eyes meet even through her sun lenses, and you both chuckle in a delighted embarrassment.

-Today was awesome.- She says: -Thanks for having cheered me up.-.

-It's because we are friends, right?- You reply with your soft voice: -We truly are.-.

A gust of wind moves your hair. You caress her cheek and proceed to take away her glasses. You want to see her fully now. Your best friend. She giggles. You remember her laugh, even if you shouldn't. Your mind is full of memories with her, but you got to actually know her just a few hours ago. And it has been fantastic.

Lunch has been pretty mild. Entering the driveway of the house, after converting your clothes back, you've noticed everyone's cars, meaning only Tom was probably missing. You stopped startled, next you approached your sister's one squinting your eyes.

You smiled. Then laughed. Then, you went in. Your brother arrived after half an hour, you greeted him with a hug and a kiss on his cheek, making sure that your father was watching that "fraternal" effusion. Obviously, the words you whispered to him were quite different from a sororal affection. You had lunch, and boy, Kim had the proverbial rainy cloud over her head. She didn't speak even when your parents questioned her about her day, then she quickly retreated to her room. First Tom, now her: you were afraid you wouldn't have any fun today, but then you remembered Heather.

-Sure you can go Tina, but I'm afraid Kim won't bring you. Do you know what's with her?-.

You gave Tom a glance, he was making his poor "I-know-nothing" face, but you said nothing. Heh, she certainly deserved it, and you did recognize Jeremy's signature.

About an hour later, you were ringing at Heather's door. Wow, just the golden knockers seemed to cost more than one of your kidneys.

-Tina!-.

-Heather!- You exchanged kisses and she let you come in. She guided you through her villa's intern, your mouth dropped a few times admiring such enormous and decored spaces, and servitude flitting around. You've seen Tina's memories, but being there in person... that wasn't a manor, that was a palace!

-Here.- You entered her room, which was as large as your living room and kitchen together.

-Mom and dad aren't home, there are just the menials but they won't bother us. Uh... where are your books?-.

-Books?- You repeated, then you woke up from your trance: -Oh, I didn't bring them! Girl, we're not spending our time together studying!-.

-But we always do.- She retorts surprised.

You smirked deviously, put your arms around her neck, and pulled yourself closer.

-We'll have some fun instead, ok?-.

-O...kay...-.

You stayed like that, your faces an inch from the other's. Was she blushing?

-And after we will be done here, we could go to the mall!- You cheerfully proposed.

-I thought you hated going to the mall.- She objected frowning. She was right, Tina hated all that girly stuff, shopping and make-up etcetera. But that was the old Tina.

-Yeah, well, it's what friends usually do, right?- Then, with a swing, you shifted towards her wardrobe.

-First things first, you need a change of clothes.-.

-W-Why, what's with these?- She was wearing a plain blouse and a pencil striped skirt; compared to your white crop tank top and shorts (just a bit less provoking than your school ones), she was dressed like your grandma. Uh, maybe your grandma wasn't wearing like that anymore... well, whatever.

-Heather, you've got a stunning body, even better than mine.- An exaggeration, but showed the point: -I think that... giggle... you should expose it more.-.

She became pink and gasped: -Tina, what are you talking about? This, this isn't like you!-.

You take her hands to calm her down, she was almost hyperventilating.

-Heather, I would never **** you to do something bad, so trust me, you'll thank me later.- You then brushed her hand with your thumb, tricking her into looking down at the wrist where you were wearing a simple rainbow rope bracelet. She had one too: they were a mutual gift of the day you decided to become BFF, and you've never put it away since.

-...I trust you, Tina.-.

-Good! Take off your clothes now!-.

She jolted ashamed, but she slowly complied. You watched in trepidation at her revealed forms, you barely refrained from jumping on her. She wasn't stacked, a C-size or less, but she definitely had some curves and the charm of the girl next door, with that shy snout. Her distress saved you from being caught with your horny glimpses. You opened her closet, losing for a second your verve. Apart from school uniforms and drabs, nothing. You rummage frantically, Heather giving you worried glances, until you found something passable: a white tank top and black leggings.

-If Kim was here, she'd tear her hair out.- You turned around and she instinctively covered her most delicate parts. Mmm... white lingerie, pretty dull too.

-D-Don't look at me like this.-.

Without saying anything, you marched to her lingerie drawers. Not that you expected anything, yet...

-Tina, that's... please close it, it's not...-.

"Why is she so worr... oh my god!" You lifted up triumphantly a box, and she whitened at the sight.

-Heather, you've never told me!- You feigned confusion.

-It was a gift! I couldn't throw it away!- She hurried to explain. It wouldn't change anything, you now demanded to see her in that black, lace lingerie.

-P-Please, Tina, I can't...-.

-Look, I won't peek, I promise.- You pressed her, turning around: -Just do it for me, ok?-.

She whimpered something, but then she grabbed the box and you hear her opening it. You, of course, peeped. Damn! She was giving you her back!

A devious idea formed in your mind. You lowered your face on the still opened closet and stealthily drew a pair of pink panties. You smacked it on your face, inhaling the lavender perfume, and opened your mouth to taste its sweetness.

"Oh... ohh... it's so... wrong... but it feels so good..." With your free hand, you massaged your moistening twat. You figured her turning around, seeing you, screaming horrified at her apparent friend's perversion. After that, since your relationship would have been irremediably compromised, nothing would have stopped you anymore... Your sniffs increased, same your rubs, but then you sensed Heather moving and quickly threw them back in place. You gave her the most innocent expression, and another time she was too much abashed to... notice...

-Wow.- You whispered.

-Could you let your hair down?-.

She disheveled her ponytail, and your heart missed a step.

-You... how can you not have a boyfriend?-.

A bell in your head warned you that you had made a terrible mistake, but it was too late. She watched down mortified, and you saw her sobbing. You instantly forgot about all your evil intentions and took your friend in a hug.

-I'm sorry, I've pushed you too far. I'm sorry Heather, I'm really sorry.-.

-N-No.- She says between sighs: -You're my friend, you only want my good. I'm sorry if I doubted you, it's just... it's just...-.

-Forget about it. I'm going out so you can change back.-.

She detached and denied: -We-We have come this far, and they're just clothes, right?-. She then proceeded to wear the one you've chosen. You should have felt satisfied but, actually, you felt more guilty. How could you hurt her like that? How could you fantasize about betraying Heather's trust? Tina's life came with her emotions, and you had to respect them, you owed her. Her love for her friend was now yours, and it felt right. For an instant, you considered the idea of telling her everything, of who you really were, hoping that she would have understood. But you couldn't. You didn't want to lose her.

She wiped her eyes and looked at you in apprehension: -What's going on Tina? Today you're so weird, you're someone else! Is everything alright at home? Is it your sister, or your brother maybe?-.

Uh-oh, she was eventually suspecting something.

-No, it's alright, everything is alright, I swear. I, I just wanted to try something, but I can stop! I can go back being, being me, yeah.-.

-But... the way you're looking at me...- She caresses her shoulder, diverting her visage: -The way you've touched me before...-.

You feel sweating like a camel, and you spontaneously, stupidly, grabbed her shoulder to prove her wrong: -No, no, it's not, I'm just, I'm only... I'm...-.

Your voices faded away. With your digits, you perceived her pulse accelerate. Your eyes meet again-but this time was different, this time you were in awe not for how your pussy felt, but for your hard beating. Her hands casually wandered along her hips in a restless turmoil, her breath... oh, you could sense her warm breath on your neck. You knew what was about to happen. And you finally knew why she had reacted like that.

-Heather...-.

Your faint voice calling her name was the last straw. She lunged forward and pressed her lips to yours.
