Regarding Applications for the LIPS Experience
As stated on the application page and the top page,
we set certain eligibility criteria regarding age and body type.
This is because LIPS is a non-profit project,
and in reality, it is operated almost entirely by myself alone.
Without setting some form of limitation,
it would become impossible for me to handle everything on my own.
Please understand in advance that these conditions
are not based on my personal preferences or tastes.
In addition, I have a full-time profession outside of LIPS.
Recently, due to an increased workload in my primary job,
the amount of time I can devote to LIPS has decreased compared to before.
For this reason,
the acceptance of new female applicants for LIPS experiences
may be suspended at any time — possibly as soon as today or tomorrow.
Because of this, not only age restrictions
but also the uncertainty surrounding the application deadline
creates a sense of urgency among many women.
For women who had been hesitating to apply for a long time,
this situation often becomes a moment that forces a decision,
resulting in what could be described as a “last-minute application.”
Rai, who kindly cooperated with this experience report,
was one of those women.

Why Rai Applied in Search of a Vaginal Orgasm

Rai has been in a long-term relationship with her boyfriend for several years,
and because they are in a long-distance relationship,
they do not have many opportunities to meet.
Additionally,
due to the length of their relationship,
their sex life had gradually become routine and predictable,
which was another major reason that led her to apply.
Although she had always admired the idea of enjoying sex
while experiencing a Vaginal Orgasm,
she believed that it was unrealistic for her
and had more or less given up on it.
However, while browsing the LIPS experience articles,
she came across the experience page,
where she saw women moaning in pleasure
and reaching Vaginal Orgasms again and again.
She found herself staring intensely at those stories, unable to look away.
The Impact of LIPS Experience Stories That Pushed Her to Apply
At first, she felt cautious and hesitant about applying,
but as mentioned in previous experience articles,
the moment she noticed the limited application period,
she made up her mind and submitted her application immediately.
Because of this background, when preparing for the experience,
we decided to treat Vaginal Orgasm as one clear goal,
while first focusing on allowing her to simply enjoy pleasurable sex,
and proceeded step by step with that priority in mind.
Experiencing the Pleasure of Internal Erogenous Zones for the First Time

Especially for women who have already read past experience articles,
there seems to be a tendency for expectations toward the experience
to unconsciously grow stronger.
Why Increased Anticipation Leads to Easier Arousal
From the perspective of preparing the body and mind for the experience,
having heightened anticipation is actually very beneficial.
And judging from how wet Rai already was at this stage,
it was easy to sense that she had come in with her expectations well built.
How Clitoral Stimulation Synchronizes With Internal Vaginal Pleasure
While carefully exploring her internal erogenous zones
and applying stimulation,

Ahhh… ahh…
her reactions clearly showed that the pleasure was gradually increasing.

Then, while adjusting the intensity and rhythm
of the internal stimulation,
additional clitoral stimulation was introduced.
As she softly murmured,

It feels good…
her moans grew louder—

Ahh… ahhh…
apparently realizing it herself,
she instinctively covered her mouth
while continuing to savor the pleasure.
Traditionally, Vaginal Orgasms and Clitoral Orgasms
have been classified as completely different mechanisms
even among specialists.
However, recent anatomical research suggests that
the clitoris has an internal structure that connects with
the vagina, urethra, and vestibular bulbs,
indicating that clitoral stimulation may also activate
the vaginal and Portio (cervical/A-spot) regions.1
Because of this,
combining clitoral stimulation can significantly enhance sensitivity
in the internal vaginal erogenous zones and the Portio area,
effectively lowering the threshold of the
“pleasure staircase” that leads to a Vaginal Orgasm.
You can see this process in the following video,
kindly recorded with her consent.
Video of Rai Experiencing Internal Vaginal Pleasure Linked With Clitoral Stimulation
In everyday sex, if a male partner lacks sufficient foreplay,
or does not clearly understand the location of internal erogenous zones,
then even if the woman is already wet,
sex often begins before she has actually reached a pleasurable state.
Some men even selfishly believe that
“as long as she’s wet, foreplay isn’t necessary.”
If such a partner is a boyfriend or a regular sexual partner,
it may be worth asking him to read educational resources like LIPS,
or simply communicating this directly.
If the man is merely a casual or one-night partner,
ending the relationship is often the more appropriate decision.
In Rai’s case, however,
even with careful identity protection,
having her boyfriend read the LIPS website
would essentially be self-sabotage.
Ideally, through this experience,
she can help her partner understand pleasurable spots
by conveying them through shared physical sensation.
Approaching Portio (A-Spot) Pleasure With the Help of Sex Toys

Being stimulated in positions that are rarely experienced in daily life,
or incorporating sex toys,
naturally increases both pleasure intensity and arousal.
For Rai,
being stimulated in the position shown above
was the most arousing for her.
She said that along with the excitement,
the level of pleasure felt almost overwhelming.
Most women likely do not use vibrators very often.
Even among those who do use sex toys during solo play,
many rely on small vibrators or wand massagers
to quickly reach a Clitoral Orgasm.
If the goal is a Vaginal Orgasm,
that approach is a missed opportunity.
If clitoral pleasure is already familiar,
trying internal stimulation as well
may lead to the discovery of an entirely new kind of pleasure.

At this point,
when the vibration motor of the Marine Beans was turned on,

What is this…?
Ahhh?! It feels so good!
As she moaned and arched her body,
it became obvious that her sensitivity
to Portio (A-Spot) pleasure was steadily increasing.
You can observe this progression in the following recorded video.
Video Showing How Understanding the “Location” of the Portio Accelerates Deep Vaginal Pleasure
To reveal the conclusion in advance,
through this experience, Rai eventually became able to reach
deep Vaginal Orgasms from internal depth—
so-called deep orgasms induced by Portio stimulation—
but at this stage, she had not reached that point yet.
What matters most is whether the partner clearly understands
“where she currently is”
on the path toward a Vaginal Orgasm.
With that understanding, combined with appropriate experience and knowledge,
it becomes possible to map out
the next steps needed to move closer to a Vaginal Orgasm.
I always proceed according to that internal roadmap as well.
The Moment Portio (Cervical / A-Spot) Pleasure Fully Awakens During Sex

Although she normally does not take the cowgirl position very often,
because this was a special experience setting,
she was able to try it freely and proactively,
appearing relaxed and open as she enjoyed herself.
It is important not to forget
that enjoyment itself is a key element of pleasure.
There are also studies showing that female sexual response
is strongly influenced not only by physical stimulation
but also by a sense of safety and emotional connection.2

In the doggy-style position, with every thrust,

Ahhh… that feels so good…
she repeatedly moaned,
gradually opening the door to an entirely new level of pleasure.
From around this point,
Rai herself seemed to become aware
that she was beginning to experience a Vaginal Orgasm.
The Process of Transitioning From the G-Spot to Portio Pleasure
As she also mentions in the reaction video
included at the end of this article,
she clearly states,

I get it now.
Furthermore,

at this stage, she had fully become capable
of achieving a Vaginal Orgasm.
Through the pleasure of thrusting during sex
and appropriate stimulation to deeper areas,
she was no longer responding only to the front-side G-spot,
but also to deeper erogenous zones closer to the Portio—
(the cervix as a deep internal erogenous area,not limited to the clitoris or vaginal walls)
allowing her to experience deeper pleasure and reach Vaginal Orgasms.3
As shown throughout this experience report,the process itself is remarkably straightforward.
You can observe this progression in the following recorded video.
Video of Rai Experiencing a Convulsive Orgasm Through Portio Stimulation
After fully savoring deep internal pleasure during sex,
in the final moments of the scene(see the photo above),
stimulation was applied just in front of the Portio with fingers,
and the instant the fingers were withdrawn,
Rai experienced a powerful convulsive orgasm.
Toward the end of the video,
while her entire body convulses,

Ah… ah…
she climaxes while moaning—
what she herself described as
“I get it now.”
Without this experience,
she would likely have spent years without ever realizing this potential.
Why Rai Ultimately Reached a Convulsive Orgasm
Originally, her body had the capacity
to experience pleasure at this level—
yet she herself was unaware of it
until she actually experienced it.
Being capable of far greater pleasure
than one can imagine,
yet never even realizing that potential,
and simply letting time pass—
that, in itself, is an enormous loss.
Which of these applies to Rai is something even I cannot determine.
Before experiencing it,there is no way to know
whether someone has developed to the level
of being capable of a convulsive orgasm.
Physical condition on the day,
level of sexual desire,
and psychological safety and comfort—
all of these complex factors are involved.
As mentioned at the beginning,
applications for the LIPS experience may be closed as early as tomorrow or the day after.
Women who are unsure about applying,
or those who have hesitated for many years,
may find it helpful to review past LIPS experience articles when considering their decision.
Feedback From Rai
Thank you so much for this experience!
It felt unbelievably good, and I had so many first-time experiences
that I still feel kind of dreamy and floating.I was able to talk about so many things,
and it was such a fun and fulfilling time♪I’m really happy I got to spend such a meaningful experience.
Thank you so much even though you’re so busy!If there’s another opportunity,I’d love to see you again (^^)
Related Articles to Rai’s Experience Story
As a first step toward understanding the location of internal vaginal erogenous zones,
the following article provides a detailed explanation of
G-spot erogenous zone development, which plays a key role in vaginal pleasure.
Please refer to it as a complementary resource.
In this experience, Rai was able to reach a convulsive orgasm,
largely due to the Portio becoming an active erogenous zone
and the resulting increase in sexual sensitivity.
Methods for developing the Portio into an erogenous zone
are explained in detail in the following article.
Because the Portio is located deep inside the vagina,
excessive or forceful stimulation can be dangerous.
If pain or bleeding occurs, stop immediately
and always proceed within a range that is safe and gentle for the body.

Notes
1・This view is also supported by anatomical reviews suggesting that the so-called G-spot is not a distinct anatomical structure, but rather a functional erogenous zone created by the interaction of the anterior vaginal wall, urethra, and internal clitoral structures.
2・This perspective is supported by clinical research indicating that female sexual response and orgasm are influenced not only by physical stimulation, but also by psychological factors such as emotional security, trust, and relational connection.
3・Recent scientific research has suggested that the cervix may function as a deep internal erogenous zone, contributing to sexual pleasure and orgasm through neural pathways beyond the clitoris and vaginal walls.
