Toys first

Your hands slide down and knead her soft ass and you purr into her ear. "I think we're both going to enjoy ourselves at school, aren't we, my pet?"

"Um... yes... uh... yes, Mistress." The girl quakes, in what seems to be fear, but you grin as you see her juices starting to moisten her thighs.

You slowly, teasingly, drag your hands up her back until they are on her shoulders and you push her forward until her tits are hanging down, her torso parallel to the floor. "Spread your legs for me, little one, and stay bent over." You quickly rush back to your room and return, seeing her naked form still bent at the waist, her hands braced on her thighs and her fingers twitching, one of them slowly sliding towards her pussy lips. "Ah ah ah. No touching without my permission, girl." You give her an admonitory slap on the ass, making her yelp, but her hands move away quickly.

Standing behind her, you begin to massage her ass again before lifting your skirt and placing the tip of the strap-on you got from your room against her entrance. As she begins to look over her shoulder in surprise, you bury the 7 inch rubber cock inside her, making her squeal. Your hand clenches in her hair as you begin to fuck your new playtoy deep and fast.
