You cop a feel, and then discovers her huge secret

You know it's wrong of you to take advantage like this, but the sight of Rachel's beautiful body makes you unable to just leave her side right away. Thus you carefully get back to her chest again, gently cupping a feel of her soft big tits, and feel the hardness of nipple press into the palm of your hand.

"Mmmm, John..." She suddenly moans, making you freeze in fear as you think that she's just caught you red-handed with groping her in the sleep. As you look to her face you find that her eyes are still closed however, and after a moment you figure she's just talking in her sleep.

"Uhmm, yeah..." She moans again, and in obvious delight, as you still haven't removed your hand from her teat. You find her reaction to be quite intriguing of course, making you continue the cautious groping, and especially due to the mention of your own name.

Soon enough you find yourself becoming a little more daring, pinching her nipples gently, and drawing some more of those soft moans from her lips. Then eventually you start moving even further down her beautiful body, caressing your way across her ribs and tummy, until you've reached curve of her hips...

By the time you let the blanket slip down to reveal the top of her trousers, she suddenly makes a restless move in the sleep however, and you quickly retrieve your hand again before you risk her waking up.

Instead she's just seeming to be get herself comfortable though, And you look curious when you notice that her pants seemed to be being stretched by something that was growing inside it. The bulge formed extended from her crotch to the right of her hip.

You pondered whether to leave it alone or touch it, curiosity getting the better of you and you decided to touch it. You reached out and touched the bulge in her pants, careful not to wake Rachel.

At the first touch you knew that whatever it was was hard, and as your hand wrapped around the thing, you started to have a hunch of what it might be, imagining that Rachel had left a dildo hidden inside her vagina the whole time and it had slipped out. The object pulsed in your hand and Rachel groaned, so you quickly took your hand away, looking to see if she hadn't woken up, but she was still sleeping in a deep sleep.

The pulsing of the thing in Rachel's pants led you to think it was something else, but you couldn't believe that she could actually have that. Then you unbuttoned her pants and pulled them down as carefully as possible so as not to wake her.

After removing Rachel's pants, you looked closely at the bulge in her panties with the most defined shape leaving no doubt what it was. You watched in amazement as the object moved inside the more elastic material and slowly escaped over the top, until your housemate's 10 inch hard cock was mostly exposed over her belly, with only its base and her big balls still filling her panties.
