A spanking!

"Oh I know!" Proclaimed the girlfriend with a sudden jolt of energy that translated into her giving Emi's tit and asscheek a couple of firm squeezes. Emi couldn't help but moan now, their teasing getting to the point where she was unmistakably wet. "Let's give this naughty girl a spanking!"

"Oooh, I like that idea, hun." The boyfriend said as he stood up from the bench, pulling Emi with him. Despite her growing excitement, she didn't want to make it easy for them. She was limp in his grip and tried to be as dead a weight as possible.

This didn't do much, as in seconds she found herself laid out across the couple's combined laps. Her tits were pressed into the denim of the boyfriend's jeans, as she felt three hands rubbing the entirety of her ass. They were playing with her cheeks, pulling them apart, jiggling them, and giving them little test pats.

Emi wanted to say something, to protest, but instead she held her tongue and bit her lower lip.

"Alright, so let's do ten swats for each lie. How's that sound, Ron?"

"Sounds good to me!"

"Would you like to get the first set?"

"Absolutely," he paused, noticing his girlfriend's judgemental gaze at his overly enthusiastic gaze at the bare ass facing the two of them. "Oh, but you know if your ass was out, I would be all over that instead, hun. Like, this is a nice ass, a great one even, but yours is actually perfect."

"Riiiight. Real smooth, Romeo." She replied, playfully.

Smack!

The first swat was a surprise, one that Emi hadn't appropriately prepared herself for. She whimpered as the pain stung a LOT more than she had expected. She hadn't been spanked since college when she failed out of sorority initiation. Maybe she still had time to resist-

Smack! Smack! Smack! Smack! Smack! Smack! Smack! Smack! Smack!

The first set of spankings came in quick succession. They alternated cheek to cheek, until both had been reddened. Emi's eyes were filling with tears, and her pussy was throbbing, begging to be touched. She knew she was sopping wet, and that once this was over, there would be a wet spot on the girlfriend's dress.

Speaking of which, it was now her turn to spank Emi's round ass. Hers came in slower, but almost three times as sharp. Each one stung in a way that Emi didn't even know was possible. Halfway through the turn, her spanks stopped aiming for the already reddened cheeks, and started aiming between the naked girl's legs. The first swat on Emi's bare pussy nearly made her cum right then and there. It made her scream out, with a shout that sounded both like one of pain and of pleasure. The second strike brought her closer to the edge, just one blow away from finally releasing Emi from the pent-up energy she had been building for some time.

She waited, hungerily, for another blow, another touch. But none came. Instead, there was a sudden flash of light, and she was rolled off the couple's laps and onto the dirty ground. She landed on her sore ass, which caused her to wince, before she realized what was going on.
