Of course he could. But only if he get's at that dick right now!

"Mmmmh, alright," Adam moaned, his eyes glued to his sister's dick. "But I want in on this!"

The cheeky smile returned to Katie's face - after all, who was she to judge an incestuous relationship between consenting sisters? She had started titty-fucking a well-endowed dickgirl she just met, after all. So Katie pulled out Sarah's throbbing cock out of her cleavage, prompting a disappointed sigh from her partner, strings of pre-cum hanging between her tits and the pulsating meat. She made a little room, and in the blink of an eye, Adam was kneeling beside her, drawing in the musk of Sarah's pre. He exchanged a look with Katie - Adam excited, Katie a bit amused at his eagerness - and grabbed Sarah's nuts, softly kneading them. Sarah remembered how he had sucked her off in the morning and her dick gave a particularly strong lurch that almost ripped it out of Katies grip.

The kneeling pair both took the object of their adoration in one hand, each stroking one half of it and started licking the tip that was now leaking pre-cum like a broken faucet. Adam kept his other hand on Sarah's balls, while Katie's strayed towards her crotch to creep into her panties and started rubbing her clit and labia with her palm. Her moans intensified and traveled right into Sarah's prick, sending little electric sparks up her spine.

Adam and Katie started moving their heads along the length of Sarah's gigantic schlong, softly licking and kissing it, planting their lips on it and lightly sucking it. Katie made sure to coat the hand that wasn't busy in her pants with Sarah's pre in order to make it as slick and slippery as possible and kept stroking the parts of Sarah's cock that weren't occupied by something else.

Sarah strained to keep her hips from pistoning forward, struggling to keep from cumming immediately from the two-fold attention to her tool. It felt amazing having four hands and two mouths service her. She tried to stay still in the hope of prolonging the moment as long as possible. The fact that Sarah was on the verge of blasting her hot seed all over the other two was not lost on Katie. With a mischievous glint, she took her free hand and moved it between Sarah's buttcheeks. After a bit of blind probing, one of her fingers slipped right into Sarah's anus. The surprising stimulation made her explode on the spot with an intensity that she never experienced before.

The first shot spurted against the wooden wall of the booth as if fired from a cannon and splattered all over it. Sarah's legs gave out, her second shot going up at an angle, clearing the wall and spattered on the floor somewhere down the row of changing booths. Katie could only just remove her finger before Sarah's ass hit the floor. Adam dived forwards to catch the next shot in his mouth - despite this being Sarah's fifth orgasm of the day, it filled his mouth and nose with its volume and squirted out of his nose. Swallowing frantically, he received the last shot in an already overstuffed mouth, more sperm being **** out of his nose, the smell and feel assaulting his senses most deliciously.

He fell back on his ass, struggling to **** down the slimy, stick goodness in his throat. Adam could barely breathe, but he was in heaven. Again, so much cum just for him!

Katie could only watch in amazement at both the amount that Sarah hat spread all over the changing booth and the display of rampant cum-sluttery she just witnessed.
