Yes

"...R-right. Want to come over today?" Your cock feels like an iron rod in your pants as you speak, images of your well-endowed family members popping into your head.

Allison pauses, her cheeks reddening slightly as the unintentional heat in her voice makes her sure that you're not just inviting her over to 'meet the family'...though in a way that's exactly what you're doing.

Giving her hips an obviously intentional extra wiggle as she slips into her pants, Allison smiles, nodding in agreement. "Of course, I'd never give up on a chance to experience your...hospitality." Her smile widens a bit. "Is your sister going to show me in again?"

You swallow, the knowledge that you've set things in motion both exciting and terrifying you. "S-she might." With a final grin at your reply, Allison finishes dressing and hurries out, obviously in a bit of a rush...and after checking the time, you're not too far behind.
