Again another 4 positions.
Sitting with the knees together and up, can be shot in about 10 different variations. Knees together, apart, feet together, apart full frontal, side on, face on the knees, leaning back, pulling the panties aside, pulling the pussy open. Shooter on the floor, shooter standing. That's over 10.
Sitting on ass or leg and other leg on floor/bed. Again can be varied in so many ways the combinations are only limited by your imagination.
Sitting with legs up. Open, closed, sitting laying, clothed, nude, etc, etc.
Standing back to camera touching toes. Or like this one. Again can be permeated over and over again. Great for leg and glamor.
In fact all these poses can be adjusted to suit many niches. And many can be shot in landscape and portrait with a little thought. If you can't get another 50 different shots from these positions give up shooting.
And for the trolls I included some shots from the 80s.
