Immediately

Tammy continued to fondle and rub your butt as you laid across her lap wincing and squirming barely able to keep yourself together. There was no telling if she was merely inspecting it or being playful as she continued to kneed, squeeze, and press along your buttocks. Either way, it was clear to you that this was her first time exploring a butt that wasn't her own.

"Hey Sam, would it be okay if I tried something out?" she asked, "I assure you it's purely out of scientific curiosity."

You bit your tongue. While you wanted to reject her request there was no way you could think to say it without revealing how turned on you were.

"Is that a yes or a no?" she asked, "I promise it won't hurt at all. And I'll even say it counts in place of one spank!"

Her refusal to give any details only made you more nervous.

She waited a moment for an answer, before shrugging, "I'm going to assume that your silence is a form of approval and just go ahead with it then."

You gritted your teeth, preparing for whatever punishment was about to come your way. On the bright side, it wasn't like she could make this experience any more humiliating than it already was.

You felt her hands each grab one of your cheeks. At first, you were confused if this was some kind of new spanking technique, but that thought was quickly dashed as she pried your ass cheeks apart.

"Wowza! Look at that cute asshole!" she exclaimed gleefully.

Shocked by the sudden exposure, you panicked, "Hey!! What the fu-!"

"EEP!"

SMACK!!!

Startled by your exclamation, Tammy struck your ass, taking you completely off guard.

"AAaahhhHH!~"

A moan, built up over the course of this interaction, erupted from your mouth.

Immediately clamming up, you pressed your hands against your mouth and prayed that somehow she didn't hear you. Maybe she was temporarily distracted by something? Or you weren't as loud as you thought? Or perhaps she had gone deaf for those few microseconds where your arousal manifested as sound?

However, upon turning your head and seeing her shocked gaping expression, you knew the truth...

"{Name}... did you just…" she exclaimed, her eyes sparkling like diamonds as she stared at you in astonishment.

**** to back peddle, you spoke again, "N-no! You m-misheard, I-"

SMACK! SMACK! SMACK!!!

"AahH!~"

Once more that humiliating moan leapt from your lips, much to Tammy's delight and your mortification.

"I knew it! You moaned! You're a spank fetishist!"

"N-no, I'm no-"

SMACK! SMACK! SMACK!!!

"Mmfph!~"

You bit your lip trying to fight the moaning from escaping, but by this point, it was too little too late. Your erection throbbed vigorously as if begging to cum. There was no way you could last for much longer.

SMACK! SMACK!

"STAAaaaahhhpp!!~" you exclaimed.

Rolling off Tammy's lap, you narrowly escaped the blonde's third strike. Bringing yourself to your feet you could feel the full weight of your arousal acting on your body. Your cock stood at full attention drooling precum as it throbbed in line with your elevated heartbeat. Of all the people to witness you in such a state, it had to be Tammy...

"Oh Sam, look at how hard my spanking made you!~" she swooned, "Who would've ever believed that the two of us spank fetishists would find one another? It must be fate!~"

You realized that the head of your erection was mere inches away from the nerdy girl's face. She licked her lips in anticipation, awaiting your next move.

"Fate has nothing to do with this! And I don't like being spanked!" you insisted sternly, swiveling your hips away from her.

"Don't lie," she giggled, rubbing her lap gingerly, "How about you lay back down, big guy? We're only… 14 hits in, I have a few more spanking techniques I wanna try out before we're done.~"

You wanted to continue arguing, you'd do anything to avoid continuing with this charade, but you were taken off guard by her spank count. 14? You had to be beyond 14 by this point, but you had no way to contest her as you had forgotten to keep count.

Tammy patted her lap excitedly awaiting your return, it was obvious she was enjoying every moment of this. You, on the other hand, felt like a cornered rat. There was no way you could survive another 26, or however many, spanks on her lap without cumming. You needed to think of a way around this before you developed a humiliating reputation!
