Unexpected company

You stop moving your hips, although your cum continues to sprout into Mia's pussy. You activate the invisibility ring and put a finger to your lip. It turns you, Mia, and the blanket invisible.

Mia looks alarmed. "Are you crazy?" she whispers angrily. "Someone's about to walk in on us naked and having sex!"

"Relax, we're invisible. Just stay quiet," you reply.

You hear the trash can fall away from the door and footsteps followed.

"That's weird. Why is the trash can blocking the door?" a male voice asks.

"Maybe someone had the same idea as we did?" a woman responds.

"I don't see anyone," the man says. "Probably was moved by the wind. I'll put it back so that nobody will disturb us."

Mia looks up at you. "I know those voices! That's my producer Tom and one of our interns. Summer, I think."

You can see the two people walking in your direction. The man looks like he's in his forties with a receding hairline and slight beer belly. The woman with him is a young redhead with freckles all over her face. Her hair in is a ponytail. She's about 5'8 and you can see her creamy thighs creeping out of her black skirt. As she gets closer, you can see that she has a pretty nice figure, though not as nice as the woman currently underneath you.

The couple walks up to a spot about 10 feet to your right and Mia's producer, Tom, lays out a picnic cloth. Summer slips off her heels, takes off her jacket, and sits down. Tom quickly joins her and they start making out right there, unaware of your and Mia's presence.

"Oh god," Mia whispers in your ear. "She's barely 20 and he's married. This is disgusting."

Your cock, which had been softening inside Mia, had started to come back to life as you watch the couple beside you. A few buttons on Summer's blouse are undone and Tom has one hand inside on one of her breasts. You can see the pale skin of her chest and the hint of the side of her other breast.

The adulterous couple doesn't take their time and they both lose their tops while continuing to make out passionately. Summer's breasts are quite the handful and her white bra is hastily removed by her older lover. Summer then undoes Tom's pants and whips out an approximately 6 inch cock. Mia looks impressed as the intern takes the cock into her mouth.

"That's it, suck my cock like you did that first time," Tom moans.

Below you, Mia is licks her lips slowly before turning to you. "Get up, I want to suck your cock," she whispers. Careful not to make any noise, you stand up and Mia immediately starts to suck your cock which is still wet with her cum. At some point, you think you can hear both women moaning in unison.

You alternate between watching the woman in front of you and the couple next to you. Summer pulled a condom out of Tom's pants and stands to remove her skirt and panties. Opening the wrapping and tossing it aside, Summer bends down to put the condom onto the portly man's cock. Once she's satisfied, Summer turns around and proceeds to sit on his cock, riding him reverse cowgirl.

Mia's blowjob has slowed down as she watches Summer bounce up and down her producer's cock out of the side of her eyes. Eventually she stops and just turns to watch them, leaving you with an erection that needs to be serviced.
