Double team me, please!

"I know this is a bit selfish, sis, but you and him double team me?" you ask.

You sister smiles, looking proud, before saying, "Of course we can, sis!"

As you walk back to the room, you lock the door behind you and rip off your shirt and skirt as you turn to John. "I though it would bring us closer to bond over something, John," your sister says, shedding all her clothes. "So why don't we bond in my little sister?" she says, removing the strap-on from the bag. You see John's jaw hit the floor as a million fantasies come true in an instant.

"Now to do this right we are going to use my new strap-on, so don't think anything of it, John," you sister says as her armband glows. You see your sister press the strap-on into her cunt before it seems to blur and merge. After a moment, you see her erect dick pointing proudly up.

As you jump on the bed, pushing John onto it, you rip off his pants in one smooth motion. Seeing him already erect, you lick his shaft a few times before sitting up and shimmying off your panties. As you do so, you kneel down putting your ass up and presenting it to John. As you look back at him you see his stunned face overcome with lust as he moves to mount you. You groan as he enters you swiftly but as you open your mouth you feel your head pulled onto your sister's cock and begin sucking automatically.

Before long, both get into it and are fucking you like a piece of meat. You revel in the feeling of being filled while so helpless as both your cunt and mouth are pounded by cocks. As you are rocked by orgasm you feel them trade places for a short time before they reposition your body. You hear your sister whispering something to John as she kisses him, before you feel them both enter you. Sis in her favorite little asshole and John in your soaking wet pussy, they pound you hard. The feeling is almost bliss beyond description, you think. Soon, though, you hear their moans reach a crescendo together as they come close to the edge or finishing.
