Do as she says

You smile meekly at Wendi and do as you're told. You sit down with your back against the wall, Wendi looking down on you from a few feet up on the bed. It's a little awkward, sitting at her feet like this, but you're happy to do nice things for her on her birthday. Wendi smiles down at you, even more devilish than before, and puts her heel against your chest. You take her foot into your hands and start rubbing again dutifully. She takes a few long, slow bites of her yogurt. She licks the spoon slowly, smiling at you all along while you rub her feet obediently. You start to feel just vaguely uncomfortable - its a slight, nagging feeling of being controlled and submissive. But Wendi is obviously enjoying herself.

She stretches her leg out in front of her and rests her other foot on your shoulder. She's done with her yogurt now. Her head is tilted back and her eyes closed as she uses you as a footstool while you massage her other foot. You had been talking, but now Wendi is totally engrossed in her massage, and she doesn't even look at you. After a few minutes you start to feel her pressing your shoulder downward with her right foot.

Wendi opens her eyes and looks at you, a sultry look on her face, but she's not smiling. She presses harder against your shoulder, forcing your body to slouch down slowly against the wall. It seems like she's trying to push you down onto your back. Her pressing foot slowly forces your body to slide down the wall until just your shoulders, neck, and head are propped up against the wall, and the foot you're rubbing is right in your face.
