She was initially able to strain on her toes with her knees straight.

Her hands flail to find a grip to pull herself up, but it just isn’t enough. The tight belt around her waist keeps her from thrusting forward… but the dildo does, too. Combined, they ensure that her clit meets that vibe with pinpoint accuracy. All she needs to do to rest her clit is to straighten her legs again, but her thighs are already trembling from the effort and her natural instinct to squeeze her legs shut is just making things worse.
