She went on like this for a full minute, a minute that seemed to take much, much longer. She then felt her brother’s cock throbbing wildly and producing much more precum than first, she knew he was close so she increased her speed even more.
Jake panted hard now. “Casey… I’m… I’m going to cum! My big sister is going to make me cum!” he yelled.
Casey let go of her brother’s wild throbbing cock with another loud plop, she then quickly grabbed it with both her hands and started to jerk him off with an insane pace. She opened her mouth close to his cockhead and looked up again to make contact with his eyes.
“Cum for me, shoot it all in my mouth, on my face, wherever you want little brother, cum!” She moaned, getting ready for her brother’s thick jizz.
Just when she stopped speaking she heard her brother scream loud. “CUMMING!”
Rope after rope of thick white creamy cum shot out of his throbbing cock, a large streak hit Casey across her face and into her hair, another one shot hard against her chin that dripped down onto her breasts. She aimed the rest into her mouth which got filled up to the brim.
Jake had never experienced something like this, he never came this hard before with his girlfriend, his sister had out done her with just one amazing blowjob. He looked down to see her covered with his cum.
She was looking up to him with her mouth open to show him how much he came. She then closed her eyes, closed her cum filled mouth and swallowed everything in one go. This triggered her own orgasm as she started to shake and tremble. It threw her off balance and she fell backwards onto the wet tile floor. Jake could see her pussy shooting squirt after squirt of juice as his sister shook and twitched.
He turned off the shower and looked back down at his sister who was now smiling.
“You okay Casey?” He asked slightly concerned.
She started to giggle. “Okay? Sweetie… You just gave your sister one of her best climaxes of her life, and you didn’t even touch me!”
Jake started to blush. “I-I think I’m in that same position, only you did touch me though.”
They both started to laugh. Casey then stood up and grabbed a big towel.
“here, let me dry you up Jake.” She gently dried her brother’s body while he gazed at her once more jiggling and bouncing tits. “You like them?” She suddenly asked him.
“Y-yes.” He responded all nervously again.
“I might let you play and suck on them in the future little brother, my breasts are really sensitive.”
Jake looked up to her. “You mean to say that this wasn’t a one-time thing?”
“Only if you want it to… But I like this little brother and I hope we can continue this, it will be our little secret.” She leaned forward and gave him and big kiss on his cheek. “I love you very much Jake and I never want to be separated from you again.”
He could feel his heart bump fast because of what his sister said. “I like it too Casey, and… I would like it if we could keep doing this. Us, together.”
Casey felt the same butterflies in her stomach that Jake also felt, she started to blush and gave him another kiss, one on his lips. She held his hand tight and reached down again for another kiss.
