“Too tight? Ok,” you say, releasing her underwear. She instantly sags in relief and starts to open her mouth, but before she can think, you grab her by the shoulder and spin her around. Sweats still around her ankles, she staggers awkwardly and ends up once more planting both hands on the counter. The frontal wedgie from before had pulled her underwear a little out of place, exposing a stretched of ass crack that you ruthlessly exploit.
Reaching down, you grip the back of her underwear with both hands and pull up as hard as you can. Caitlyn squeals even louder as your initial yank actually forces her feet off the floor and her underwear to shoot up her ass, revealing her two pale, perky cheeks.
“Fuck, no, no, no, no, no,” Cait babbles in a high-pitched gasp while her feet kick uselessly in the air.
“Yes, yes, yes,” you reply cheerfully as you set her down readjust your grip. Faint memories of your recent dream in your head, you bunch up the back of the pink pantie in one hand while planting another hand on her shoulder for leverage. With a small grunt, you start pulling her underwear up past her head. By all rights, the pink fabric probably should have ripped at least a bit by now but, instead, it just kept stretching up while the gusset dug deeper and deeper into her lower lips and ass crack.
One last tug and pull brings the back of her waistband up and over her head before you release it. With small snap, the elastic slaps the back of her underwear to her forehead and sticks, completing your sister’s atomic wedgie.
