Let the boys spank her

"Hey kids, wanna see what a really firm butt feels like?"

The woman's eyebrows arc up in protest, but it's a less than useless gesture. There's a split-second blur of motion, and she finds herself on her knees with her face pressed up against the ground and her curvey ass up pointing up in the air, and her knees tied together with rope making it almost impossible for her to shuffle away. Her tail of golden hair is spilling down over her shoulder, partially obscuring her face. You stand behind her, motioning your hands to present the cheeks spilling from behind her pink panties towards the boys. You ignore her objections coming from the other side and dig your hand into the waistband of her panties before yanking them halfway down her legs in one tug. Sammie's friends look with mouths agape at the sight, sunlight glinting off the curvatures.

"Forget Sammie's ass, who'd like to get their hands on this fine specimen right here? I think we should give them a good slapping and see if they wobble."

The three simultaneously snap out of their stupor, running forward and jockying for a good position to be able to rear their hand back as far as possible for a hard slap. This is truly the greatest day ever.

The woman quickly changes her tune, "Wait, stop, you damn rascals keep your paws- Ah! Ow! OW!"

The trio each deliver a firm smack with the flat of their hands, sending a wobble racing across the woman's fit buttocks that quickly comes to a rest each time. The sound of a long series of rapid slaps reverberates off the walls of the nearby buildings, punctuated by the plus-sized woman's distressed shrieks that become noticably more **** and embarrassed over time. After a minute of this the boys slow their pace and stop, and the lead boy tugs at the panties around her legs, pulls it as far back as the elasticity of the fabric allows, and then releases to let it snap against her already reddened ass. The noise it generates is even louder than any of the slaps thusfar.
