"Mmnn....mmf...slp...mm!"

He watched the woman next to him, on her knees in front of the couch, head head bobbing in the lap of a man he hardly knew. Her plush lips were stretched wide around a thick, hard shaft, making it glisten with her spit as she drooled on it, passionately working her lips and tongue up and down its veiny length.

He'd never seen her like this before, at least not from this angle. Not with another man that wasn't him. He had a moment to admire her enthusiasm and skill, the sight of which made his own cock stiffen up inside his pants.

A strong, insistent hand cupped his chin and turned him back to face the crotch yet another man, seated beside his friend. His other hand was drawing an equally impressive prick out of his underwear, holding the towering member at the base as it throbbed with each pulse.

"She looks amazing, right? Why don't you show her what you can do, though?"

Seeking a particular type of scenario: A man and a woman with some kind of established relationship get picked up or seduced by a pair of men (or futas) and end up experiencing new things together as they get fucked side by side.

Possible setups (open to others as well):

• A married couple celebrate their first anniversary by going back to the bar where they met. The crowd is a bit rowdier than they remember and after having a few too many drinks they wind up in a nearby hotel room with a pair of young studs plowing them from behind.
• A young couple recently moved into a new apartment and realize that the neighbors above them have almost weekly parties. When they go up to complain they get invited inside and one things leads to another, resulting in the pair on their knees servicing a room full of horny guys.
• A pair of fraternal twins, brother and sister, having been close all their lives end up going to the same college together and even sharing a room. When the two guys across the hall realize they're not a couple they become regular fuck buddies instead.
• After a couple's relationship starts going stale they try opening up and seeing other people. When the woman has much more luck finding dates and getting fucked she decides to share those horny men with her partner, even if it takes some convincing.
• When a young man comes home from college he's surprised when his mother doesn't meet him at the door, and even more surprised when he walks upstairs to find her in her bedroom with a pair of men. When they notice him they decide that, even if he's a guy, two cum dumps are better than one.
