Teach her to please you with her tits

“What now…?”

You look down at Jessica's chest as she massages your cum into it, her swollen breasts glisten with the wet coating of your semen and her own sweat, you can't resist the chance to pleasure yourself with them.

"Because you've been so good, baby sis," you tell her "I'm going to teach you something VERY special. Guys dream of this because not many girls can do it, it's called a titty fuck and you need large breasts to be able to do it properly"

Jessica looks at her tits and presses them together thoughtfully, then pushes them up towards you eagerly.

"Do you think my breasts are big enough Luke?" she asks holding them there as if waiting for you to inspect them.

"I have no doubts" you reply. Jessica was chubby as a teenager and took after your mother in the cup sizes, So her breasts had always been big. And the fact her breasts stayed the same size when she lost all her weight almost gave her a porn stars figure. You figure her to be at least a D size, probably bigger.

"Well let's get started" you say "Now since your breasts are nice and slippery with my cum, you don't have to worry about making them slide to much. All you have to do is place them on either side of my cock and squeeze them together." She does so eagerly and you feel your younger sisters soft lush breasts smothering your cock. You sit there enjoying the sensation for a moment then guide her hand movements so she begins mashing her breasts together and moving them up and down your pulsing shaft. You moan softly as her young swollen mounds slide up and down your dick sending jolts of pleasure along the shaft.

"Hmmm that's very good Jessica" you says softly "Now as the head of my dick emerges from between your tits, you can give it a light suck or maybe a lick to stimulate it"

She nods and starts begins to lick the top of your cock as it surfaces from between her ample cleavage. The feeling of her warm tongue carressing the head of your dick combined with the sensation of her breasts mashed about your shaft makes you groan openly. On the ground beside you Britney moans softly also in her half-conscious daze. You remember the connection you made between Britney and yourself and realize that despite being in a euphoric state, she is still experiencing everything you do! You smile wickedly then turn back to Jessica and her titty job.

You prompt her to speed up, and she slowly gains speed. Soon she is jiggling her tits about your cock furiously and has locked her lips over it's head, sucking and tonguing it eagerly, her short red head swishing about each time she twistes her head. The bouncing and mashing of her breasts around your shaft is driving you crazy and though her oral style feels a bit amateurish it is more than enough to make you feel like cummin hard again.

"Oh yeah Jessica, that feels amazing!" you cry, she doesn't reply, instead she stays focused on bringing you to climax. The sensations are finally to much, the sight of your cute younger sister sucking your cock and bouncing her soft young tits around it's shaft make you blow. You cum hard into her mouth, causing her the **** a little in suprise.

"Swallow it Jess," you say sternly, and she obeys. You watch her suck and swallow your jism as you cum down her throat and finally you feel spent. Jessica looks up at you worshipfully.

"How was that Bro?" she asks, eager to please you.

"that was very well done, Sis" You say smiling "you are going to make a very good slut for me."

"I hope so!" she replies "I love you cock and your cum, so... are you going to fuck me now?"
