Yes, she does.

"Alright Jessie, i will do it, but only if you also honor your word", Jenny responded.

"Yes sis, i knew you would do it", Jessica replied, "Now if you excuse me", She said as she began to lift her shirt.

"Wow, what are you doing ?", Jenny asked, "Honoring the deal", her sister responded as she trew her shirt to the ground and began to remove her bra, _"_Now, when are you going to begin ?", she aked, as she stood completely topless while holding her bra in one hand.

"sigh, i guess i have ****", Jenny replied as she began to undress with the help of her sister.

Moments later, she stood completely naked aside from her backpack and her shoes, with her clothes having being trown on the bathroom alongside her Sister's ones, "Man, this is rather awkward, isn't it ? " Jenny nervously commented , as she was naked next to her topless sister, "We will only have to get used to it, no big deal", her topless sister replied.

As the two girl went downstairs to eat their breakfast, they got noticed by their parents, who were understandably surprised that, not only Jenny was honoring her word, but also that her older sister was topless.
