Training course

      “A harness is a really useful tool,” says Renee while arranging handcuffs on a bed frame. With two satisfying clicks, Robin’s wrists are restrained above her head. Renee takes a moment to appreciate her fine body, fully naked as Renee instructed earlier. The girl looks at her with wide eyes, always eager for the lesson to come, which is quite adorable.       “It has a lot of uses,” Renee continues, showing the harness to Robin. “Remember to make sure the size’s right for what you plan to do.” Renee sees that Robin’s curiosity is piqued as she presents a second harness, this one different – with less straps and in a different shape.       “This one goes around your hips.” Renee indicates the harness in her right hand, the metal buckles shining in the light. “But we’ll leave it for another lesson.” She puts it on the bedside cabinet. “Today we’re using this one.” Seeing Robin’s questioning look, she explains, “It goes on your head.”       “What?” asks Robin, scrunching her nose. So innocent.       “Here.” With the dildo ready, Renee puts the harness around Robin’s head. Part of the toy goes into her mouth, silencing her for the time being – she doesn’t need to speak for the next part, after all. The rest of the dildo stands straight up, and judging from Robin’s wide eyes, the girl understands now where this all is leading to.       “Pets don’t need their words.” Renee revels in the anticipation radiating off of her trainee. It can be a true joy for a dominant one day – Robin would make an excellent submissive, in Renee’s opinion. However, it’d be a waste of her real potential. The spark is there, and now Renee needs to make sure that it doesn’t go out or grow too big.       “At this point, some boys will serve you earnestly,” Renee continues with their lesson, eager herself for what’s to come. Her fingers close around a toy in her pocket, and once again the cargo pants she bought a while ago prove to be useful.       She makes sure that Robin’s attention is on her before adding, “But some boys need a little bit of motivation.” Renee takes out an egg vibrator from her pants’ pocket. The apprehension in Robin’s eyes sends pleasurable shivers down Renee's body.       Robin shudders as the vibrator is inserted into her pussy. Lube isn’t needed because the girl has become so wet during their session that the toy slid in with ease.       “Eager pet, aren’t you?” Renee teases.       A beautiful blush spreads out on Robin’s cheeks, the embarrassment making her look away from Renee. Though, at the same time, she’s become even more aroused.       “Ready?” Renee asks and without waiting for an answer, she turns on the vibrator on low.       Robin moans and shifts her hips, trying to find more stimulation. Too bad, because the lesson has just begun, so it will be a while before she’ll be allowed release. But it’s not like it’s Renee’s problem.       Renee spanks Robin’s left asscheek lightly. “Don’t think I forgot about this hole.” Renee traces the rim, and Robin shudders. “Next session,” she says, which is met with a relieved sigh. The girl will learn in time that the more time Renee has, the worse it gets for anyone she’s playing with.       It barely takes time for her to undress and straddle Robin’s face, her rim touching the tip of the dildo. She’s prepared herself earlier so that she doesn’t lose precious time now. The toy fills her up deliciously, the girth just perfect for her needs. She gasps when it bottoms out, pressing against her sensitive spot.       Robin starts squirming, now that her breathing is obstructed (or maybe it’s because of the vibrator — who knows). Fortunately for her, Renee doesn’t plan to sit on her face for the whole time.       She pulls herself up, and when the tip nearly leaves her hole, she slowly sinks back down with a moan. Her cock is hard now, dripping precum, the pleasure from the toy too much to ignore. But Renee doesn’t want the fun to end yet, so she sets a slow pace. Robin shifts under her occasionally, the low vibrations taunting her with pleasure that’s too far away to bring her to an orgasm. She’s too silent for Renee’s tastes.       Renee tweaks Robin’s nipple, and the girl yelps. That’s more like it. "The sounds the boys make are part of the fun," Renee says. "Especially when they lose control." She puts the vibrator on the highest setting, which results in a muffled shout.       She doesn't know if Robin has heard what she's just said, but it doesn't matter now – she will ask her about it later during the annual test. If Robin fails, that means more fun for Renee, but the girl is an attentive student and despite minor troubles, she passed everything with excellent results.       Robin starts squirming and moaning in earnest, as always when she is nearing her climax. Renee coos. "Does my girl want to come?" She rolls her hips, so that the dildo rubs against her prostate. Muttered gibberish answers her.       "Don't cum before I tell you to," Renee says, quickening her pace, her thigh muscles getting sore from the strain. She finds a perfect angle, so that the dildo hits her prostate with every thrust, getting her closer to the edge.       When Renee feels close, she grants Robin the awaited permission, and the girl comes, her body spasming. Renee isn't far behind, as it takes her only two jerks on her dick to cover Robin's body with her release.       It takes her a moment to get her breath back, the orgasm stronger than anticipated. Robin squirms under her, and Renee chuckles when she realizes the vibrator is still going, probably feeling painful to the sensitive nerves. But the girl has something of a masochist in her, so Renee doesn't turn the toy off, and instead, she leans over her body and starts rubbing Robin's clit. The girl moans (or cries – hard to tell with the gag in) and soon comes for the second time. Renee gets off of the dildo, her muscles shaking as they change positions, and unbuckles the harness from around the girl's head.       "Good girl," Renee says, smiling. "Remember that it's you who decides on the boy's pleasure. They don't know any better."       Robin nods, her breaths still heavy from the ordeal. Sweat beads on her forehead and her hair is in total disarray, but to Renee she looks beautiful, even more so than before.       Renee unlocks the restraints and massages Robin's wrists to get the blood flowing. "Anything hurts?"       Robin shakes her head. "No," she says, flexing her fingers. "Good," Renee says, satisfied. "You should always check."       "I'll remember." Robin sits up and looks at Renee. "Thank you for the lesson."       So precious, Renee thinks. "You're welcome. Same time next week – don't be late."
