The doorbell rings

By: Metaldreamer

The sound seemed to get Christy out of her post-orgasmic daze. "It's open, come in!" She screamed, loud enough to be heard all the way to the front door.

That made you panic. "Christy!"

Seeing your reaction, and realizing you both were not in the best position to be caught on, she screamed again. "I-I mean, don't come in!"

Were your hands and face not covered in her cum, you'd have face-palmed.

"Too late."

The new voice made you both jump; turning to the door, you see a girl reclining against the frame, arms crossed under her C cup.

A redhead, a bit older than Sarah, is staring at the two of you with amusement.

Christy stands up, a bit nervous. "O-oh, hello Claire. Doug, she's my neighbor and friend."

"And Fiona's friend, too. She had mentioned her boyfriend, and here we meet, after having such naughty fun with your girlfriend's sister!" she says in a false shock that still makes you both wince a little in guilt. "By the way, you should remember to close the curtains if you don't want to be seen."

Christy does face palm at that, while you can't help but look at the clear bulge in her jeans."Look, I... okay, there's no excuse or this, but please don't tell Fiona," you beg.

Why couldn't you control yourself? Now your relationship is certainly ruined.

She looks down at your still kneeling form, her eyes never leaving your cum covered mouth as she saunters closer, biting her lip. Though not as gigantic as your girlfriend and her sister, she is still a head taller than you.

"Well, a good friend wouldn't lie, but I guess I shouldn't rat Christy out. What to do, what to do..." She pretends to consider her options before smirking at you. "I guess you will have to convince me."
