Sarah undoes them

The brunette's eyes meet those of the blonde wriggling in your arms as she steps before Frannie and moves both hands to the brass stud at the teen's belly. After a moment's struggle with the too-small jeans, Sarah's little fingers manage to undo the button from the slot.

Frannie wriggles some more in your hands as she realizes this is really going to happen.. her schoolmate is really going to take her pants off in front of you!

"Sarah..stop!" she continues to plead.

Sarah merely curls up the left corner of her top lip in anger as she stares at Frannie and grips the tiny zipper tab with one hand as she holds the two flaps of black denim together with the other.

The tearing open of the metal teeth seems to fill the living room foyer as you hold Frannie tight to you. The idea of the babysitter stripping her friend causes your cock to swell against Frannie's full ass through both your slacks.

"Ewwww! Gawd!!" Frannies squeals, apparently very familiar with what that warm bump growing behind her asscleft is. Her squirming away from it only makes it grow further in the tight confines of your slacks.
