You signal your friend with a knowing glance, and they move in to gently hold her arms above her head, just tight enough to keep her still—but not enough to stop her from squirming. With her wrists softly restrained, you trail slow, deliberate circles of your hips against her soaking core, teasing every sensitive inch. You feel the delicious tension in her body growing with every breathy gasp, every restless twitch. You’re driving her wild, making her want more without letting her have it—pure, delicious torture.
