Instead, the story focuses on high-school romance, comedy, friendship, family life, school festivals, entertainment clubs, and the chaotic experience of having a famous idol as your mother.

Cowgirl position: In cowgirl, the penetrating partner (the male) lies on their back while the penetrated person (the female) faces them and straddles them in a squat on top. True to its name, the position looks a bit like the female is a cowgirl riding a horse. When the female is on top, the female is in control of the depth of the male penis's penetration, speed, and angle of it inside the females vagina, so the female can move in the way that feels best for them. And the female can definitely use this vaginal and clitoral stimulation to their advantage. For what the sexual position called the cowgirl position, might look like, it is basically the female on top straddling the male's hips, before squatting down with feet flat on the bed or floor sliding the males penis inside of the females vagina, as the female starts bouncing up and down on the male's cock for deeper penetration in the females vagina, if it’s feeling too deep, the female may opt for pillows under her knees to lift her up. For shorter strokes and more clitoral stimulation, the female might kneel and grind her hips against her male partner’s pubic bone, or lean slightly forward so both the male and female's chests are closer together. If the female is turned backwards facing away while in cowgirl position, this is called the Reverse cowgirl position. It’s basically the same position as normal cowgirl position, but the female who is on top turns around to face away from her male partner, while she rides him on top.
