(Her Secret Fantasy, continued by LMS...)

“Let’s go for a proper punishment,” you say nervously, rubbing your girlfriend’s arm.

“Great!” Rachel replies, beaming with happiness. “Let’s see how naughty you’ve been by the end of the week.”

The next week goes by fairly normal, you do small things to try and annoy Rachel but nothing really seems to bother her that much. However, you see your opening when Rachel tells you her best friend Monica is visiting at the weekend. You come to the conclusion the best option is to flirt with Monica in front of your girlfriend. If that won’t piss her off then nothing will, plus it means that Monica might get involved.

When Saturday comes you arrive home from a day out to find Monica is already there. You enter the house and go straight to the kitchen, finding both Monica and Rachel having a drink and chatting away.

“Oh, hey Ross,” Monica says sweetly, giving you a warm smile.

“Hi Monica, how are you?” you ask, ignoring Rachel. This annoys her slightly but you know you’re going to need to go further than that.

“I’m great thanks,” she says, taking another sip of her drink. You take a seat next to her and engage in conversation, occasionally flirting with her, which seems to be annoying Rachel.

“I’m going to get another drink,” Monica says, standing up.

You see your opportunity to really push Rachel over the edge. As Monica walks past you reach out and give her ass a hard slap, followed by grabbing her large bumcheek and beginning to squeeze. This enrages both Monica and Rachel.

“What do you think you’re doing?” Monica screams in horror as you remove your hand from her ass.

“Right that’s it” Rachel shouts, not giving you a chance to answer Monica before she rounds the table and grabs you by the ear.

In a flash Rachel has you over her lap with her best friend watching. Before you can say anything to Rachel she lands a hard slap on your ass, quickly followed by another.

“That’s what you get!” Monica growls. “Fucking perv.”

“Ahhhh, Rachel stop!” you beg as another spank befalls you. She doesn’t reply but instead undoes your jeans, sliding them down to your ankles, followed by your boxers. You go red with embarrassment as your backside is bared in front of Monica.

“Go on Rachel,” Monica cheers as your girlfriend spanks your naked ass. The ferocity of her strikes has tears forming in your eyes after a few minutes.

You lie there in defeat as Rachel relentlessly spanks your rear, getting motivation from Monica, who cheers her on. After ten minutes of this tears are flowing down your cheeks as your ass is already red.

“Get up,” Rachel says sternly, catching you by surprise. You don’t say anything as you slowly stand up, turning to face Monica.

Again Rachel grabs you by the ear and leads you to the kitchen counter. She roughly bends you over the counter, presenting your reddened backside to both women.

“Don’t you dare fucking move, Ross,” Rachel snarls as she exits the room. You don’t move an inch as you wait on Rachel returning, even when you can hear Monica taking photos of your spanked rear.

Rachel returns with her dreaded wooden hairbrush in hand and takes her place behind you once again, readying the brush.

“Ahhhhh!” you scream in pain as the first strike falls swiftly on your exposed rear.

“Shut up!” Rachel growls, landing the second spank to your ass. You accept your position and endure as Rachel brutally spanks your backside. After ten minutes of this your ass is dark red and covered in angry red lines from the brush.

To your relief she stops, leaving you a crying mess with a dark red ass. She turns to Monica, giving her a sly smirk.

“Your shot,” Rachel giggles as a large smile creeps across Monica’s face.

“Gladly,” she laughs, taking off her belt and readying and stepping behind you. She lines up the belt before getting ready for the first strike.

“This will make you think twice before groping me,” Monica snarls before letting the belt swing through the air before it connects with your bare flesh.

“Ahhhhhhhh!” you wail as she sets a steady rhythm, whipping your ass as hard as she can with her belt.

You get spanked for what feels like forever by Monica before Rachel exits the room again, going upstairs. She returns a few minutes later, brandishing two large ten-inch strap-ons.

“Oh fuck yes!” Monica laughs, dropping her belt and taking a strap-on from Rachel. She straps herself in and moves behind you again.

“Let’s see?” Monica giggles. “What should I do with this?”
