Getting a bit more familiar wouldn't hurt

As you stare at the phone you can't help but notice Becca - or rather your ample chest, the still chilly feelings keeping your nipples hard and causing your heart to quicken, a thought crosses your mind;

"Y'know, dinner with the Parks could wait....maybe it is best to reschedule" you whisper to yourself in a familiar, yet surprisingly foreign feminine tone.

You pull up the chat with Choa and send her a quick message:

"Hey Choa! I am so sorry but I am going to have to cancel on dinner tonight - some really pressing matters came up. I'd still love to stop by but just not tonight"

You take note that Becca has Choa's number, maybe you can get closer to Choa that way - using Becca as a sort of wingman for yourself. Or maybe just use the POS app on her. Regardless, as per your message, you have some pressing matters to attend to.

You work your way back to the bathroom, staring at an new face, you are so used to seeing Becca upset, her faced contorted into angry expressions but now all you see is nude sister, with a slight blush on her face and a distinct gaze of excitement in her eyes...

Your hands wander across her form, from her delicate collar down to her ample chest, massaging them together almost clumsily but you could care less about technique right now. Grabbing your nipples, you fondle them every so slightly, the sensitivity plus the cold sends shocks of excitement through you.

However, it is a tad too cold and you decide the bed might be the better move, exiting the bathroom your work your way over to the bed, covering yourself in Becca's wool blanket. Christ Becca goes to bed every night with this sight? You think, as you peer down the blanket.

With a gulp of excitement, you drift your slender hand down to her pussy, running your fingers over her delicate lips as you clutch your tits with the other hand. Your fingers edge across her lips, her pussy practically begging as you bite your lip. You race inside without wasting anymore time, plunging your fingers deep inside your sisters pussy, as hitched gasps escape your lips. Your legs open up seemingly on instinct as your other hand moves to your clit, subtle moans filling the room. A swelling builds inside of you, "you're so fucking tight Becca holy shit" you whimper as you probe her hole, the blanket seemingly soaked in her juices. Picking up the pace, your hips twitch I'm gonna cum I'm gonna cuumm You whimper...before hearing a knock.

You are still covered in the sheets, your hands slick out of your throbbing pussy, begging for release. Without any confirmation John walks in the room with headphones on, seemingly oblivious to the erotic noises you were making earlier, "Hey Becca" he says inquisitively, aren't you suppose to be at dinner with the Parks? Someone just knocked on the door and left some food with a note and left"

It seems John might want a proper explanation after ruining your session. You can always call it quits, explain it to John and then clean up. After all that's what Becca would likely do. On the other hand, you can explain to John while getting off under the covers...It is not a very Becca thing to do but your pussy is on fire and maybe John could help you with that....
