やみこちゃん大辞典！？第二巻「性科学大実験」やみこ先生が好きなえっちとコンドームとは！？ Yamiko-chan's Great Dictionary!?
Volume 2 is 'Sex Science Great Experiment'!
Yamiko-sensei, who is active in the world of sex science,
appears wearing a lab coat over her school uniform.
From a woman's perspective, Yamiko-sensei talks about pleasurable sex while demonstrating it.
The opening interview is about 16 minutes.
First, Yamiko-sensei talks about her favorite plays.
Her various sexual fetishes are revealed!?
Next, she introduces in detail the three types of condoms we bought together.
Normal type, dotted type, and warming type.
She also introduces a rotor that attaches to the dick, and a penis strap-on.
After the interview, we start with the penis strap-on experiment.
First, she wets the penis strap-on well with her mouth.
It's basically a blowjob.
The movement of her tongue is clearly visible and erotic...
Then, insertion in the cowgirl position.
Yamiko-sensei herself grinds her hips on the rock-hard penis strap-on.
At the end of the penis strap-on segment, there's some private talk from Yamiko-sensei.
Apparently, there's a ●●●●● in her room.
And since she has a penis strap-on, she puts it on and
plays with ●●●●●!!
Check the main feature to see what she usually does.
Next is the segment experiencing the differences between the three types of condoms and raw sex.
Yamiko-sensei blows the real dick, which is the experimental tool, to make it big.
Then, while inserting, she explains the differences.
Sensei seems a bit troubled explaining the differences!?
She explains the differences very clearly, so it's interesting~!
After experiencing each difference,
We suddenly decide to do a quiz 'Guess the Condom' where she has to identify the three types of condoms and the raw dick.
To make it so she can't tell which one is being worn or if it's raw,
We insert quietly in doggy style and move a little.
There are comments like 'Ah~, it feels good' as the quiz proceeds.
See how many Yamiko-sensei gets right in the main feature!
After that, we experiment with various positions using the condom that felt the best.
We check the differences by position.
In the final missionary position, we attach the rotor to the dick.
The combo of 'vibrating rotor' + 'insertion' gets sensei even more excited!?
Especially in the last two minutes or so, the pleasure resonates with Yamiko-sensei,
and her white skin flushes red.
The finish is a release into Yamiko-sensei's mouth!
And she swallows!
She also explains the taste in detail.
Please watch this great experiment with Yamiko-sensei, who is currently active in the world of sex science!
