U"So, what's first on the agenda?" Akeno asked as she undid her ponytail and let her flowing locks down and both beauties stripped down to nothing.
"First things first..." Rias said. "A long, passionate kissfight."
The girls didn't waste any time as they immediately brought their mouths together and made out like horny teenagers. They pressed their massive breasts together as their tongues wrestled lustfully, one hand palming the other girl's ass cheeks, the other hand in the other girl's hair. They ram their tongues all throughout each other's mouths and lips, sometimes stopping to suck on them as the room filled with the sounds of slurping and lips popping. The girls moaned, their pussies soaking as they kissed lovingly, running their hands through each other's soft, luscious locks as they tongued each other like sex starved animals. They closed their eyes as their bodies gave into the pleasure, their nipples jabbing into each other, their drenched cunts sliding together, their tongues twisting and battling for dominance. Eventually, both girls finally stopped to try and catch their breath after kissing for half an hour.
"You're not bad but no one kisses like I do!" Akeno boasted.
"Please! I could outkiss you and all the other girls at the same time in my sleep!" Rias replied.
"Then bring it, bitch!" Akeno challenged.
"C'mere and kiss me, slut!" Rias said.
They resumed tongue kissing, their competitive spirits ignited. They kissed with far more ferocity than before, the first round just being a warmup. They slammed bodies together and pulled hair as Akeno grabbed Rias's tongue with her lips and passionately sucked on it like she does with Issei's dick. Not even trying to control her saliva, she drooled over Rias's face, letting it drip down to her buxom chest. The girls' pussies ached for stimulation but that would come later. Right now, they had to outkiss their rival and the idea of their boyfriend watching them just turned them on even more.
Rias finally managed to corner Akeno's tongue and began sucking on it longingly, mimicking her rival's earlier actions. Akeno moaned as her best friend and sexual rival dominated her tongue. She would've loved nothing more than to just fuck Rias's brains out right then and there and she knew for a fact that Rias wanted to do the same to her but this was a competition first. Rias slurped Akeno's tongue over and over again until Akeno finally pulled back, signaling her forfeit.
"I win!" Rias cheered as she hopped up and down, her tits bouncing with her.
"You are an amazing kisser" Akeno admitted. "But we've got a whole week of debauchery ahead of us."
"You're right, babe." Rias agreed. "So, let's not waste any time."
