Oh boy, with the tiniest of glimpses into the personalities of each girl, the main factor that would make the difference would be well, who would you consider the most physically attractive? Unfortunately, in this case, ALL of them were, at least to you, equally sexy. Sure, two of them had one of their "assets" biggest of the entire group (those being either Ana's bust or Andrea's ass), but overall their physical appearance what comparable with the others, while both Antonella and Ariana, although having a "balanced" body, both had their physical quirks which made them stand apart (Antonella had her big muscles, while Ariana had her sheer height). Only Antonia had nothing extremely remarkable, physically speaking. Okay, she had a medium-to-large chest, and a nice butt, but nothing truly outstanding, especially in comparison with her friends. And also, she lacked any quirk or physical detail that made her stand out: she was slim, but in the right way, and she lacked any marked muscles nor her height was abnormal, to say the least. No matter how you looked, Antonia was the least physically impressive of her group.
But perhaps, that was the outstanding thing about her: she was the most "normal" of the girls, in physical terms, which made her for that reason stand out to you. That's why you started to feel a bit attracted to her, at least for the simple thing that her "within average" physique set her apart. However, it would be other factors that would tilt the balance in her favor.
For you, the moment you looked at her, something...inside you, was telling you "this girl would take good care of you", "like a mother to a son, or an extra caring wife to her husband", things like that. And indeed, Antonia emanated a caring "aura". Also, she was the oldest and most mature of the group, so if you wanted to have a girl with the most possible experience and by extension have it a lot easier for the both of you to adapt to your future relationship, she was the best alternative.
So, three factors decided the outcome: her "normal" physique, the likely higher experience and maturity, and above all... her feelings. Your inner voice was telling you: "if you want a giant girlfriend, one that is willing and able to go the extra step to ensure both your safety and comfort, she's the one."
You sigh, for you never thought you would be picking a girl primordially for what your instincts were telling you. But deep down, you knew this was the correct choice, the best choice.
You looked at Antonia and said:
"I've made my choice: Antonia, I choose you to become my girlfriend. Let's have a long and beautiful relationship."
Antonia blushed, before starting to smile: yes, he choose her! A part of her was overwhelmed with how joyful the situation was!
However, she remain utterly calm: there was no need for wild and rapturous actions, there would be a better, and more appropriate time and place to let herself loose with her boyfriend.
She gently grab you, and brought you close to her face, then gave you a nice, big kiss. The first of many you would have, no doubt of that.
She gently pressed you against her, making sure to put the right amount of force in the right places to increase the chances that her tiny boyfriend would have a gorgeous time. And indeed, you had a nice time: her lips were soft and warm, and you could feel anything but bliss.
She then left you in the palm of her free hand, in the perfect position to recover a bit. She asks:
"Bueno querido, ¿cómo encontraste nuestro primer beso? ¿Fue de tu agrado?"("Well darling, how did you find our first kiss? Was it to your liking?")
"Yes, it was lovely, and very nice indeed. You're quite the good kisser." you reply, smiling.
Antonia blushes and replies:
"Awn, ¿tú crees? Me alegra que te haya gustado, y algo me dice que será el primero de muchos que tendremos."("Awn, do you think so? I'm glad you liked it, and something tells me it will be the first of many we'll have.")
The other girls, meanwhile, groaned a bit, feeling a tiny bit sad about not getting picked. Ana said:
"Hombre, yo pensaba que lo tenía a él con mi gigantesco escote. Tal vez le gusta otras cosas a Denis."("Man, I thought I had him with my gigantic cleavage. Maybe Denis likes other things.")
"Sí ese el caso, ciertamente no eran traseros. Yo tengo el más grande de todos, pero no fui escogida; bueno, mejor suerte con el próximo."("If that's the case, they certainly weren't butts. I have the biggest of them all, but I wasn't chosen; well, better luck with the next one.") Commented Andrea.
"¿Tal vez le gustan chicas más femeninas? Eso es la única razón que encuentro porque no fui escogida."("Maybe he likes more girly girls? That's the only reason I can find why I wasn't chosen.") Said then Antonella.
"No lo creo amigas, mírenme: yo soy solamente más alta de lo normal, pero no fui escogida. Lo único que estamos seguras es que por una razón u otra, Denis prefirió a Antonia. Aun así, ignorando la competencia que teníamos, una de nosotras ahora tiene pareja; Eso es algo merecedor de celebración, ¿no creen?"("I don't think so, friends, look at me: I'm just taller than normal, but I wasn't chosen. The only thing we're sure of is that for one reason or another, Denis preferred Antonia. Even so, ignoring the competition we had, one of us now has a partner; that's something to celebrate, don't you think?") Replied Ariana, with a slight smile. She was still sad just like the rest of the girls about not getting picked, but she wouldn't let that blind her to the joy that one of her best friends got a boyfriend, and she wanted to make that clear.
All the girls change immediately their demeanors, agreeing with her. Sure, they weren't picked, but it was still a very good event that one of the group got now a partner. They all commented again, saying that Ariana was right, and start to praise you and Antonia. She started blushing, for she didn't expect this sort of behavior after such a tight competition. Yet at the same time, she was very happy: their friendship was genuine, and no matter if they had disagreements or small rivalries, they would stand together, as they had always had.
She said:
"Gracias, gracias, por todo esto. De mi parte, les deseo lo mejor, y que encuentren chicos dignos de ustedes, amigas. Se lo merecen."("Thank you, thank you, for all this. From my part, I wish you the best, and that you find boys worthy of you, friends. You deserve it.")
She then returned her look to you, and ask:
"Ahora, si soy sincera, estoy curiosa de cuales fueron tus razones de escogerme: yo soy la chica físicamente más normal del grupo después de todo, eso es innegable. Denis, si no te molesta, me gustaría que me digieras."("Now, if I'm honest, I'm curious what your reasons were for choosing me: I am the most physically normal girl in the group after all, that's undeniable. Denis, if you don't mind, I'd like you to tell me.")
Her calm voice, combined with her aura, prompted you to speak up, leaving nothing hidden between yourselves. You start explaining to your girlfriend, giving your reasons as to why you choose her.
After the explanation, she made a nice big smile and said:
"Así que...me escogiste principalmente porque tu sentiste que yo te cuidaría como ninguna otra."("So…you chose me mainly because you felt that I would take care of you like no other.")
"Yeah, that's a way to say it. I don't know, but every time I looked at you...something inside tells me you're going to take good care of me. And besides...I've always wanted my hypothetical girlfriend to be the extra caring one...is a small fantasy of mine." you reply, blushing both with embarrassment and also joy. To be able to speak to a girl, about your most secret fantasy...it was a dream come true.
Antonia brought you again to her lips, giving you another kiss. Then, after again pulling you back, she said:
"Vaya vaya, eres un chico muy sensible. Me gustan esos tipos de chicos. No te preocupes, tu sueño será realidad: te protegeré, y te cuidare como ninguna otra."("My my, you are a very sensitive boy. I like those types of boys. Don't worry, your dream will come true: I will protect you, and I will take care of you like no other.")
You nodded in agreement. As before, deep down, you felt that she was telling the truth and that picking her was the best option.
What happens next?
