Yes (more vanilla version)

John nodded emphatically. Erin smiled and snapped her fingers, producing a bottle of soap.

"I'll rub it onto your dick and then you're going to rub it into me." Erin explained. John groaned as he slowly pulled his dick out from between her ass cheeks. Erin made it worse by suddenly clenching them, pulling him back in.

"Stick your tip in for just a sec?" Erin pouted at John, the twinkle in her eyes showing that she intended to try something. John sighed and embraced her, inserting his tip into her butt.

"Glusuctos." Erin whispered. In a flash, John felt his cock be sucked up into her asshole. His hips began to grind against her's.

"That could be useful. Okay, here's your reward!" Erin smiled and viciously tightened her sphincter. John screamed as the hot senior sucked an orgasm out of him.

"Oh my god sis. That was incredible." John gasped. Erin laughed back at him.

"I'm glad my little brother liked coming in his big, strong, sexy sister's cock-devouring asshole." Erin teased him, a cheek of her fleshy ass slapping him with each word.

"Make me come one more time? Any way you want? Then I'll wash you with my penis!" John begged.

"Fine, but you have to let me take you to dinner tonight then. And you have to agree to be my assistant at tryouts." Erin negotiated.

"And Tessa?" John asked. Erin nodded.

"And Ellis." John demanded.

"I can make that happen, but promise me you'll take good care of your sisters." Erin made a cute face (all of her faces). John nodded.

"Glad to do business with ya. Now get between my tatas, I need to practice this." Erin said, pulling John up into a mount position. He smiled and gladly thrusted into her admittedly average boobs for the Academy.

"Do your worst, big sis!" John said. Erin smiled and began to stroke him with her breasts. Precum rolled through her valley. She suddenly stopped and gasped.

"I know what'll end you in seconds!" Erin said, giving John a courteous kiss before she resumed stroking, only this time, she pumped her tits in opposite directions, causing his whole shaft to feel at least one of her soft globes at once. She went for ten seconds, but was confused when John hadn't come yet.

"What's not working..?" Erin said, confused.

"It feels amazing!" John said, trying to thrust into her breasts for more. Erin's eyes twinkled again.

"Watch my face the whole time." Erin ordered. She resumed stroking, but now she wore an adorable pout that was the deciding factor. Before ten seconds were up, Erin's cute pout was covered in jizz.

"Aaah. Oooh. Erin that was amazing." John gasped. Erin laughed.

"You're my weak little baby brother! Don't worry babe. We'll strengthen you up so much this season, Katherine will be terrified of you." Erin promised, removing John's softening penis from her tits. She rolled her eyes and gave it a kiss. It instantly popped back up and reached her lips again. Erin giggled and kissed it with a little tongue this time. It reached full mast and stood at attention, ready to serve her. She lathered the cock up and John began rubbing it down her arms, pausing at her hands to receive a gracious tug. Next, he moved to the top of her chest. He gently washed the top of each breast, Erin's nipples kissing his head as he brushed by. He diligently scrubbed her valley, accidentally shooting into it again and having to scrub again. Erin laughed and blew him a kiss. Continuing on, he stuck his dick into her underboob, reaching neverbefore fucked places. As he moved down, she contracted her washboard abs for John to scrub. He scrubbed further down her torso, reaching her snatch. John gently teased the labias and the clit with his tip before moving on to her legs. He slowly rubbed down her silky smooth skin, tickled occasionally by a misshaven leg hair. Every time he was tickled, a jet of cum blasted into the water. He rubbed down every millimeter of her feet, stopping between her big toe and small toes to recieve a stroke and again beneath her toes where Erin would curl them and gently grip his length. John began to travel up the backs of her legs, blasting his white dick milk every time her leg hair tickled him. He soon found himself tucked into the fold beneath her perfect bubble butt. John thrust into to clean it before moving over the cheeks. From there, he hot-dogged her crack until it was clean, accidentally causing another orgasm and more cleaning. After fixing his mistake, John glided up and down Erin's back, finishing the job.

"Well done little bro. You need anything before we head out for breakfast?" Erin asked.
