You choose to fuck Jess

You give Jess your answer, but not with words. You just smile with Sasha's face kiss her before swiftly grabbing her boobs. You then grab Sasha's and say "Touch them, babe. I wanna feel you squeeze them in your hands like I squeeze yours."

She obeys. You spend a few more seconds grabbing each other's tits before moving on to your private parts. You finger her and she grabs your still soft dick. Seeing your little guy is still too tired to stand upright, you retract it inside Sasha's body.

"Mini Dave is gonna need a few more minutes to recover, but until then, Sasha's pussy is yours"

After fingering each other a little, Jessica decides to lay flat on the ground, inviting you for a 69. You position yourself in front of her and you begin simultaneously sucking each other. You both moan in pleasure for a few minutes and you come way before Jessica. Having a cunnilingus done to you is still...pretty new to you after all, while Jessica has experience on the matter, so she is not as overwhelmed by the sensation as you are.

After finishing Jessica up, you both take your breath for a few seconds before Jessica says "Alright, babe. Get up now. Let's get to bed. I'll wear you tomorrow after the sleepover"

"Ah...but babe...you think I'm done with you? Yes, Sasha's pussy has come..."

You make your dick come out of Sasha's pussy right into Jessica's mouth underneath.

"...but mini Dave has had all the time he needs to rest and now, he's hungry. You wouldn't want that poor guy to go to bed hungry, right?"

"Chno! I chwouldn't chwant him to!" says Jessica, her voice muffled by your shaft plunged deep inside her mouth.

"Good. Then be a good girl and feed him!"

Jessica starts eagerly sucking your shaft. You then feel a more familiar kind of pleasure as you feel her lips applying pressure on your penis while Jessica's tongue dances with it. Jess has always been good at sucking you, but the fact as she does it, you feel your boobs colliding into each other and that when you moan, it's not your own voice that you hear, but Sasha's sweet feminine voice makes it better than any blowjob she's ever given you as your normal self. It's a blend of the familiar and the alien that multiplies the pleasure tenfold.

You then look to your right and see yourself in the mirror. You see the face of a woman, a beautiful woman, a sexy woman. One you desire, one you've had sex with just minutes before and that you totally would like to have sex with again in the future. This woman is having a powerful orgasm and this makes her look even sexier. You then think of the best part: this woman, this beauty...is YOU! You own her body. You do whatever you want with her. You can even use your own genitals when having sex with other women. In fact, you're having sex with one RIGHT NOW! Your own girlfriend who is totally fine with it and is eagerly sucking your man bits from below. There, at this moment, you feel like the world belongs to you. You can do whatever you want with anyone and no one could ever stop you...

This is too much. All of this situation pushes you over the edge. You begin thrusting into Jessica's mouth with an animalistic intensity. This isn't just a regular facefucking. You're fucking her mouth with the exact same intensity as you fucked Sasha's vagina earlier, holding ABSOLUTELY nothing back!

Jessica struggles not to **** as a long and hard stick of flesh keeps getting shoved on the back of her throat over and over. Her eyes water and her cheeks turn red. Luckily for her, you cum fairly quickly. You were never gonna last long being this aroused anyway.

You get up and admire your work. You find Jessica, trying to catch her breath, her mouth dripping with saliva, Sasha's juices and LOTS of your cum. She dutifully tries to swallow it all and as she does so, you get an idea.

"You know, Jess. With all the great pleasure you've given me and considering how much Sasha likes to fuck, I think she could get just as addicted to being worn by me as you are if I zapped her empty skin with the brown pen..."

Jess finishes swallowing, looks at you for a moment and says "Knowing her, yes, probably, but...I feel like this is starting to get out of hand. I've given you permission to fuck other women while wearing me, now you've fucked my mouth wearing another woman...I'm still your girlfriend, Dave! There's got to be something only I can do with you, otherwise, I'm not special"

"Hmmm...Alright, so here's what I suggest. I can recruit as many girls as I want to be able to wear them while having sex with you or to wear you while having sex with them, but you are the only one who will be allowed to wear me. Deal?"

She thinks it through a little, before answering "Deal."

"Great!"
