Train her some more...

You give yourself a few days' rest before returning to the motel. Since your last encounter, you've been teasing Gemma with photos of your cock, texting her about all the ways you'd be fucking her brains out. Right on time, you hear a knock at the door, and you slowly take your time getting up to open it. Gemma is standing there, wearing a long coat, looking up at you anxiously with her dark brown eyes. You motion for her to open the coat, and she undoes the strap and pulls it aside to reveal that she's wearing nothing but a pair of black panties. Her nipples are hard in the morning cold, and her skin is covered in tiny goosebumps. You reach forward and grab her small breasts, kneading them in the palm of your hand and pinching her nipples between your fingers, causing her to wince in pain.

"Good girl," you murmur approvingly. You step back and let her come into the room, pulling off her coat as she walks past you and leaving her only in her panties. She looks nervously at the lengths of rope laid on the bed and turns to you apprehensively. You motion towards the bed, directing her to lie down, which she does so obediently. Despite her hesitation, you can see her bristling with excitement.

"Are you ready to get fucked?" you ask. She smiles and nods with excitement, and you move to the foot of the bed and peel off her panties. She's already wet - a small strand of sticky goo clings between her panties and pussy, only snapping off as you pull them past her knees. You grab the rope and tie her tightly to the corners of the bed, the cord digging into her skin and causing red marks to appear on her wrists and ankles.

With a grin, you pull the enormous vibrator from under the bed and turn it up to its maximum speed.
