Yang giggled as she watch her "little brother" grow a blush after she had ask him to apply sunscreen to her back. She had taken him to the beach, well to be specific, she took him to her own secluded spot. No one around but them, just as she wanted.

Feeling the coolness of the sunscreen touch her back caused a small moan to escape her lips.

"A-ah! Sorry sis!" Jaune said, staying in his shy little brother role. Yang giggled at his response

"It's alright there bro! Now, that youve got my back, now you gotta get my front." Before he could say anything, Yang had already flipped over, her big uncovered tits out for all to see. She bit her lip when she watched a certain appendage stir a bit In his swimming trunks.

Jaune gulped as he stared at his big sisters huge swells.

"Cmon Jaune, you don't want me to burn do you?" She innocently as she swayed her breasts a bit. Jaune nodded, apply sunscreen to his hand as he got to work to cover her front.

"Ahh~" yang moaned as hands pressed onto her stomach, ensuring not to let his eyes linger.

"T-There!" He exclaimed, ready to put away the sunscreen.

"Nope~ you forgot the rest of my front." She giggled as she leaned forward, shaking her breaats. "Can't forget my girls little bro."

"B-but s-shouldnt you do that y-yourself?" He trembled a bit as Yang leaned more, causing him to fall on his butt as she hovered over his small body. Her breasts pressed against his chest.

"Oh but I'm sure you would love to do it, after all, I see how you stare at them. Really couldn't keep your eyes off since we got here."

"I-wha not true!" Jaune exclaimed, Yang couldn't help but grin at his lie.

"Do you want your big sis to burn though?" She playfully pleaded, Jaune gulped as he reached for the bottle only for Yang to grab said bottle and toss it behind her.

"H-hey! How am I supposed to put sun screen on you now?"
