Back to Quinn

After you all recover, the three of you shower together. You of course give extra attention to the two sexy bodies with you, but beyond squeezing and sucking this shower is all business. Once you're all dried, your mother puts her robe back on. She pulls you close and gives you a deep kiss, arms around your neck and tongue exploring your mouth. You pause to think about Robin but notice she's smiling at the show. "I can't thank you enough, baby. That was incredible." She then turns to Robin. She surprises your sister when she reaches around and grabs Robin's bare ass, pulling their bodies together. "I can't thank you enough either, sweetie." She says before giving Robin a kiss just as passionate as she gave me. As the kiss breaks, your mom keeps her face close to Robin's and says in a low tone, "I hope you'll consider inviting me to share in your fun more. Think about it." Your mom then gives you one last lustful look and heads for the door.

By yourselves again, you pull Robin back to the bed and jump in together. You start making out, recounting your exploits as you do. You open the discussion. "Watching you suck my cum out of Mom's ass was almost as hot as fucking you."

Robin reached down and strokes your hard cock. "Oh, I could tell. Believe me!"

It's not fair but you slide your cock back inside her pussy and start fucking her. You suck on her hard nipples before you keep going. "So... What about you? Did you like it? Do you want to do more?"

Robin is already moaning from your slow penetration. "Yesss..." She admits, but you knew she had **** but to agree while you are fucking her.

You take a moment to ponder what direction to drive this in. " Do you want another crack at Quinn?"

Now Robin moans loud and starts riding your cock, her tits jiggling as she slams herself down on your meat. "Yes! I want to watch you fuck that little slut. Would you like to make her another toy for us? A busty young slut for you to use when you prefer that to mommy?"

Now it is your turn to get loud. You grunt and thrust up hard into Robin. "Fuck yes!" Is all you can manage.

"Mmm, I can feel you so close to cumming baby. Fill your slutty sister's pussy up!" She suggested as she picked up the pace. You happily oblige her and grab her hips. You slam her down and hold her on your cock as you explode and start pumping inside her. She arches her back, grabbing her tits and squeezing them as she shakes. She cums hard on your cock, then slumps down on top of you and kisses you.

After a little affection, Robin leans over to the night stand. "What are you doing?" You ask. Robin merely opens your phone again and slides your cock out of her pussy. She aims the camera and snaps a pic of your cock right next to her pussy, covered in her juice, while your cum is slowly starting to leak from her cunt. She taps away at the phone for a second before laying back down with her head on your chest and handing you the phone.

You look at what she has done. It was a text to Quinn. The picture with the caption. 'He still wants this pussy, slut. Bet you wish it was you leaking his cum right now, don't you?'. Your screen tells you that Quinn is typing back. 'Fuck! I need it again! Is that right now?'

You just write back 'yep.'

The screen shows her typing again. 'look how wet I am for you' she texts. Then a moment later a loading screen followed by a close up shot of her pussy similar to what you two had just sent her, minus a cock of course. Robin moans at the display of lust over her man's big cock. The screen shows loading again. This time it's a video. It shows Quinn's fingers pumping in and out of her pussy. Then she withdraws them, pausing to show her juices all over the fingers. Finally she brings them up to her mouth and slides them in, moaning as she tastes herself. "I'm going to come over there and let you have your way with me again. I'm going to show you what a perfect little slut I can be for you, and maybe this time Robin will stick around to find out how good I taste when you turn me on."

Even having just been fucked, Robin moans and grabs her tits, squeezing hard and pinching her nipples. You have no idea where this came from. The rule just made sharing with other women permissable. It didn't encourage it or make it enjoyable for her. That just seemed to be a kink in her you never knew before, but you know now and you're loving it. As much as you want to act on this, it's been a long day. You text back, 'We will but not tonight. You're going to have to be worked up all night and come to our room in the morning.'

You get a crying emoji response, plus a pout from the sexy woman next to you. You give her a look and she knows why you're doing it. "I know, we're both exhausted, but fuck it's just such a hot idea and I can barely wait! But you're right, we should get some sleep."

You smile and kiss Robin's forehead, then turn back to the phone. 'the wait is just going to make you enjoy it that much more. See you in the morning, slut' you type before putting it back on the night stand. You don't wait for a reply, you just draw Robin in and you are both quickly fast asleep, resting up for tomorrow.
