A new exercise

Monica's face twists and there's a small bit of hope in you that she's leaning toward giving you, or particularly your dick, a much needed break to calm down. Although before she can even speak up, a voice interrupts.

"Ooh, Miss Monica!" In the very front row of the pack of ladies, a red headed woman who seems to be around college age raises her hand. "You showed us how to protect us from behind but what about if they grab you while they're in front of you? You can't really move your hands or legs to kick..."

"Very good point, Sarah! This attack is a little less likely considering the attacker has less control over you in this position but it's still possible all the same. John, come over here." Monica seems to have completely forgotten about your break and beckons you over. Your dick is still twitching underneath your clothes and you barely hold back a whimper as you shuffle towards her.

"W-what about that break, Monica? We can-"

"Nonsense! This'll only take a few seconds. Now go ahead and hug me and hold on as tight as you can." Monica stood completely still, smiling while keeping direct eye contact. Without much choice, you decide to get this over with...the only thing on your mind was to not lose control of yourself in front of all these women!

And so your move forward and wrap your arms around the muscular body of Monica; you feel her firm breasts press against you tightly though you make sure to stick your ass out a bit to prevent any contact with your bulge against the instructor's stomach.

The class is filled with constant whispers, you hear a couple embarrassing comments about your ass, though Monica only seems to be standing completely still and unable to move from within your grip. "The first few seconds, the two of you will be stuck in a stalemate so this means you must react quickly. John here is physically stronger than me so I'm barely able to move, however I must use what little movement I have."

The very last thing you expected was for Monica to lift her hand a bit and softly smack it against the right side of your rear. You jump at the contact and feel a blush reaching your face after being swatted in front of so many people. Instinctively you loosen your grip and this is precisely when Monica acts.

Forcing her arms out of your grip, Monica doesn't escape like you initially expect. Instead, she wraps her arms around your own body and pulls you tightly towards her; you can't help but bite your lip tightly because this meant your covered erection was pressing tightly against her muscular stomach!

"Spanking a man's ass is very emasculating for them so you must use this as an advantage. His instinct will be to pull away to prevent you from hitting him again and instead grab you from another position. Before he does this, you will need to trap him yourself the same way he did to you. Though it won't be very long before they try to break free. Go ahead and struggle, John."

You didn't need to be told twice! You immediately try to tear away from Monica's tight hold but are caught off guard as you feel the smaller hand once again smack your ass HARD! You gasp and stop struggling. Though this does nothing to stop Monica from raising her palm and swatting your other cheek with an equal amount of strength. You gasp as she begins to roughly spank you over your shorts, shocked that the smaller woman can hit so hard!

Monica transitions between smacks. From your left cheek, to your right cheek, to the middle of your ass, then repeat. Her slaps are very firm and you have to stop yourself from yelping! Monica speaks loudly over the sound of her swats. "Normally you would consider a man's testicles to be his weak point. So it is very humiliating for a male when you instead control him by his butt cheeks instead, a body part that both genders own. So you must remember to begin spanking him as hard as you can so his priority is to escape the embarrassment rather than hurt you. You can continue this until you either get help or spank him into submission; the former is more likely of course."

You let out another loud gasp at another hard swat from Monica and the women cheer and giggle at the sight. You can't really see behind you but you do hear Sarah's voice speak up.

"But Miss Monica, does it even hurt over his clothes? Especially if he's wearing thicker pants, your hand might not be very effective over them and he'll recover quickly, right?"

"Hm..."
