An interruption.

You are just idly toying with the purple dildo, when Carla unexpectedly walks into the room.

Seeing the two of you in the buff, she gasps, and asks with a shocked look on her face, "What are you guys doing? And why do you have my dildo?"

You are trying to think of a response, yourself a little shocked, when Kat says, "Um, we found the dildo here, and we got a little carried away. We were going to clean it."

"You used it?" she asks incredulously, her eyes getting as big as saucers.

Kat nods sheepishly. Carla seems at a loss for words. Her mouth opens several times like she's about to say something, and then it just closes. She looks kind of like a fish. Then her eyes light upon your hardening cock, and she can't seem to take her eyes off it. It's not even half erect but still an impressive length. You wonder if you have a chance of fucking her too, so you decide to stroke your rigidness and see what she does. You see Carla's cute little tongue lick across her lips. She starts fidgeting a bit, shifting her weight from one foot to the other. She bites her lower lip. Your dick is now standing straight up, your nine inches fully extended. Kat sees what's happening and watching Carla get hot and bothered watching you is turning her on. She puts her hand on her mound, beginning to rub her pussy lips. Carla's eyes dart over to Kat's groin. She can't seem to figure out whose sex she should be looking at.

"Why don't you come over here, and I'll show you what we were doing?" you ask with lust in your voice. “Don’t worry. It won’t bite.” You motion with your free hand for her to join you.
