The vagina is a fine choice.

"Well....if this has to be done...then vaginal should be fine, right?" Even though there is way more questions to things that you can think of at this time, it's gotten to the point that it's just easier to go with things than even ask any anymore. The Harpy woman seems to be in a similar mood about it from the way she laughs. "A little simplistic, but I'd be lying if I said that it was getting old."

"So...just kind of...yeah...take it and put it in...." Keito half looks on the situation while Asuka takes a few idle glances but overall seems bored out of her skull. "Do you two have to be here?" It feels like a thing to ask right now.

"What? You think I want to look at your dick?" Despite asking that, Keito makes no real attempt to move from his spot along the wall. "I've already seen it before." Asuka glances at her fingernails, seeming to just be generally impatient with the situation.

"Since none of you are in any hurry...." The harpy has already closed the distance between you two before you can notice and makes a fast swiping motion that sends your jeans to the floor before there's a chance to realize what exactly she did.

Her other hand already rubs along the bulge in the underwear, and she grins a bit. "You're already hardening, aren't you?" She's already pulled it out without any warning and starts to give it a few light and playful strokes. "It has been a while, so I'm up for just about anything."

The dick coming into the state of full erection does prompt a quick look over from Asuka who still seems rather apathetic. "It's really more than I would give you credit for." Despite opening your mouth to make a response, it's cut off by the clawlike fingers of the harpy touching your lips. "Shh...don't worry about her. For now, you're all mine."

She doesn't wait before pushing downward and letting the rigid cock in front of her split between her folds. Her inner parts seem incredibly moist as she places a couple of fingers above her vagina and parts it a little to give a better view of her penetration.

"Still pretty decent for a mature woman, isn't? But it's not all I have going for me." Grabbing your hand, she quickly places it on the soft mounds of her large tits, allowing full feeling of it. The parts of the fingertip along her nipple can already feel it stiffening. "These are a step up from those girls your age, aren't they?"

Here humping gets much faster as if attempting to completely impale herself onto your dick while still mostly standing straight and her body mashes in closer with her breasts compressing onto your body, only given some parting room by the hands exploring them.

"Don't hold back, cutie." Her urging, combined with the feeling of her wet pussy make an extremely powerful effect. "I'd love to keep playing with you...but you are supposed to let it all out first, aren't you?" As soon as the harpy makes the comment, her vagina muscles suddenly contract and feel much tighter than what they did before.

"Mmm...I feel it twitching. Squeeze my nipples a bit." Following her instruction, it starts with a light touch on her nipples that gives a light reaction before making a more firm one that gives louder moaning from her. The fondling of her tits is much more assertive and the harpy has a completely blissful look from the whole experience.

Without realizing it, it went from her initiating most of it, to being on the receiving end of your dick pounding into her insides. "Ah..ahh. Rough sex is the best. Use my pussy like a cum dump!" Almost as soon as she says it, everything squirts into her vagina as she still continues to grind against you working to her own orgasm which is quickly followed while playing with her nipples and her letting out a loud cry in ecstasy.

She takes a few breathes, still not removing herself from where she is and your cock is already getting rigid again inside of her body. Before there is time to debate a second round, the bright flash of everything on the floor distracts you from a decision. "Alright. That looks like enough." Keito gets off his phone and Asuka does the same as they walk into the magic circle. It happens too fast to see what he did, but an even larger flash blinds everybody, before everything disappears.
