>>19237441Ina would probably be the type to make faint gasping sounds and quiet confirmations as you gently push in (easing her in is probably essential). Contrary to what you might expect, it's better to penetrate whilst facing her, which lets you look her in the eye, kiss her, lick her nipples, kiss the nape of her neck, nibble her ear lobes, and anything else you need to do to help stimulate her (teasing her pussy and clit go without saying). Once she's eased in, going at a fairly slow but passionate and persistent pace gets the best results and despite being kind of reluctant to begin with she should have no trouble having a strong and lasting orgasm.
Gura is tricky because she's so small, you have to do a lot of careful prep work. Plenty of lube is essential and rimming is highly recommended. Letting her essentially ride in your lap is probably the best option, since weighing down on top of her can be overbearing and uncomfortable. She'll be kind of cheeky to start off with ("You want to stick it where? Eww, that's stinky~") but once you start getting to penetration she'll drop the facade and get nervous, so it's important not to rush her. Soundproofing is pretty important because she will squeal loudly throughout, especially during initial penetration and even moreso during orgasm, so make sure to deal with that if you don't want your neighbours accusing you of child rape. Gura cums from anal fairly easily and will probably manage it at least once or twice before you finish, so be bear with her throughout. Also, she squirts like you wouldn't believe, so have something absorbent in place or do it in a bathroom. (Please not that the above only applies for Gura; anal with Gawr is not safety approved by the Association for Chuuba Buttsex and any injury or death resultant from any attempts is at your own risk. Yes, she will ride you for hours and she will bite and probably try to asphixiate you. You have been warned).
Ame has less difficulty starting of the three, though she'll playfully push you around to start with ("Nooo, you can't put it in my butt, that's groooooss~"). Once she's past that stage she's pretty eager and will definitely take charge, prepping herself, pushing you onto the bed and straddling you to insert you herself. Penetrating her is easier than the other two but her inexperience in proportion to her enthusiasm may make it a little awkward at first, so be sure to guide her ass and hips as she gets used to riding you (and yes, she will tease you while this happens, and it's great). Ame is also one of the louder ones, both in general reeing and monkey screeching and in making terrible dirty talk (her sex talk is extremely aggressive but really stupid. And she will laugh at it, it's brilliant), so bare that in mind to be considerate of your neighbours, since it's the sort of noise that would stop them from talking to you for weeks. Ame's orgasm is, needless to say, extremely fucking loud and powerful, and she's probably the only one of the three to want to go more than one round straight away (if you were using a condom the first time she definitely won't want one the second).
In final assessment, Ame is the best for the first time and the most balanced for the long term, Ina has the best growth potential since she really learns to feel it after some practice and Gura's the most romantic (she'll always want to snuggle and have sweet pillow talk after).
*Gawr is technically the best overall, but that hinges on your body being able to take it. Most can't.
