You chuckle, for its immediately clear what "room" you find most appealing to sleep in. You say, in a teasing tone:

"Well, I've always fantasized about being inside a gorgeous giantess pussy: sleeping on it is part of the whole deal!"

"My my, it seems like I've got quite the "pussyphile" tiny here, hehe. Don't worry my love; I also love to have you inside there. Come, get back into your bedroom my love." your girlfriend replies, before grabbing you and shoving you gently inside, feet first as to allow you an easier exit once you need to come out. It also helps the fact that she's able to get a last look at your face (and to send you a kiss) before you are fully inserted within.

She pushes you as deep as possible, leaving her with all tightly closed. She then gently pats the area where you are, giggling as you move slightly when you react to it. She then whispers: 

"Now, stay tight...unless you want me to shower you with my cum again, hehe. Otherwise, let's enjoy our first sleep together as a couple. I love you."

Soon enough, she turns back around, laying on her belly and closing her eyes. 

And as sleep starts to cover your mind and make your eyelids heavy, you say, even though you're not certain she can hear you:

"I love you too Abigail. You've no idea how thankful I am for being here, in a situation like this, for real. Sleep well, my beloved."

And then, you go to sleep, the sounds of your giantess' heartbeats a lullaby to your ears.

Eventually, however, the rest come to an end, for lunch is ready. Now, who comes to wake you up?
