You're going to have to...

You shut your brother's door behind you, grateful for the lock he had installed recently, which you slide across too. Then, you reach down and pick up a couple of pieces of the dirty laundry scattered across the floor. With a pair of your brother's dirty underpants in one hand, and the biggest pair of pantyhose you have ever seen in the other, you tiptoe over to where she is sleeping.

Gently, you lift her wrists to the headboard, and tie them there with the pantyhose, and then, when she is firmly secured, you stuff the dirty underwear into her mouth, her awful snoring meaning her mouth is conveniently open.

She moved a bit, but didn't wake up, so you moved down to her legs. Luckily, she was only wearing underwear, so you could stretch those over her flesh to pull them off. Then, you went hunting for lube in your brother's draw.
