Her father.

"...That's probably my father! I forgot to mention to you that he's stopping by," she explains, not the slightest hint of worry on her face.

Oh, shit. Come to think of it, you never got to meet her father! When Tia moved in, you only saw her mother, Cassandra, helping out with her daughter's move-in. You remember Cassandra being quite supportive of her decision to move in with you. On a side note, you remember being awed that your girlfriend's mother looked quite young and fit, and similar to Tia, she had large breasts, possibly even bigger than her daughter's breasts!

What fills you with dread is that unlike Cassandra, Tia's words about her father rings through your head.

Uhm...yeah, he wasn't really supportive of me moving in with you, but I tried to explain to him that I feel more comfortable moving in with a friend I know rather than some stranger. My mom was a little worried too, but she's definitely more open-minded. She told me she's okay with the arrangement now, but when I called my father, he was still against it...

Sounds like a father looking out for his daughter, which you totally understand. But here you are with an unexpected visit on your hand and you are carrying his daughter around you like a child with the intention of rocking her in the shower.

You are scared.

BANG! BANG! BANG!

"We better hurry and open the door. I told him that I wasn't going anywhere today," she explains. Didn't she realize that you and herself are both naked?

"Shouldn't we change?" you suggest, starting to sweat. You realize that it would mean Tia's father has to wait outside longer, but there is no way around it.

Tia curls her lips. "We could, but my father is very impatient. He's not going to like the fact that he'll have to wait."

You pause for a moment, a little concerned at how easy your girlfriend is taking this.

"Tia," you call seriously, pulling her slightly away from you so that you could see her face. In reaction, she shifts her hands from your back to your shoulders so that she doesn't fall while wrapped around you naked. You could feel your hard cock touch the bottom of her ass as she leans slightly back.

She raises an eyebrow at you. "What?"

BANG! BANG! BANG!

"Tia! Are you in there?" Tia's father yells. You can hear his father growing a little worried and impatient in his voice.

Fuck!

"Why are you so calm about this!" you exclaim, "Aren't you worried what your father might think if he sees us like this?"

Tia blinks a few times, looks down, and starts to see what you mean. She hums and then smiles reassuringly at you. "I guess I'm a little worried, but I don't think it'll be a huge issue. There's nothing wrong with us being like this, even if I think it is a little strange. I'll just tell him we're lovers now."

Your eyes widen and you realize that she's accepting all of this, not just with your immediate action and commands. She feels content with any decision you make or action you take, even after the fact!

Come to think of it, there should be no worries with meeting her father like this either! As horrible as it sounds, he could meet her father right now while carrying his daughter naked, and have him accept the situation!

Would that be too cruel, though? Maybe it would be better to, at least, change into some clothes so her father doesn't get a heart-attack before you could explain the situation and relationship to him.
