"Oh?" Joanna says with a raised eyebrow, intrigued by your request. "Well, I've never compared... but I guess there's no harm in doing that now." She hesitates for a moment before slowly moving aside to make room for you to remove your own penis from your pants.

As she sees it fully exposed, Joanna can't help but let out a soft gasp of surprise and admiration. "Wow," she breathes, looking at it with wide eyes, "you're much...

much bigger than I expected." She reaches out tentatively, cupping your erection in her hand and carefully measuring its length. Her face flushes with arousal as she feels the hardness against her palm. "It's... almost eight inches?" she whispers incredulously, unable to hide her awe at your size.

With a shiver of anticipation, Joanna moves closer to you, pressing their bodies together and positioning herself so that your erection is nestled against hers.

As you ask why they should wait until tomorrow to change positions, Joanna's curiosity is piqued. "You want to try something different right now?" she asks with a mischievous glint in her eye. "Well... I guess there's no harm in experimenting."

She leans forward slightly, placing one hand on your shoulder and the other on your knee before gently pulling you toward her until you're straddling her lap.

(After switching positions as you suggested, Joanna wraps both arms around your waist, holding you close while you sit astride her.)

"So," she says softly, nuzzling her nose against yours, "how does this feel?"

Her hands roam over your back lightly, exploring every inch of skin they can reach through your clothes.

Her heart swells at your words, and she presses a gentle kiss to the crown of your head. "Why, thank you," she says with a blush, trying not to sound too full of herself. "I just try to be the best roommate I can." She takes a deep breath, feeling more relaxed and at ease than ever before.

She giggles playfully, giving you a mischievous look. "Oh, you want me to pick you up and carry you around like a princess?" She pretends to consider it for a moment before breaking into another laugh. "Okay, okay! If that's what my handsome prince desires..."

With surprising strength, Joanna effortlessly scoops you up into her arms, cradling you against her chest as she stands up from the couch.
