"I've been so horny thinking about your visit over the last few days," Mom whispered to me, placing a hand lightly on the crotch of my jeans. "And all the things I want you to do to me. My ass has been missing your attention." She pressed her lips sensually to my neck, slowly kissing up towards my ear. "Once Stacy leaves... mmm, I am going to use you so hard."
"Are you guys in the kitchen?" my sister called out from the living room.
"Yes, we're in here." Mom gave my crotch another squeeze, then moved a polite distance away from me before my older sister entered.
"Hey, I'm gonna go ahead and get the kids home. Great seeing you, Tyler! Maybe I'll come back over tomorrow and we can hang out some more."
"Sure thing," I responded. Stacy moved to give me a hug. I felt a little guilty for savoring the feeling of her sizeable breasts up against me, but knowing what I was about to do with Mom made it not seem so egregious. Stacy, with her back to Mom, couldn't see her seductively place a finger to her lips and suck on it playfully while she maintained eye contact with me.
Gathering her things, Stacy went to get her two kids situated in the minivan to head home. Mom waved out the front window as I moved up next to her.
"What's first on our schedule?" I asked, moving my hand to Mom's ample ass and giving it a firm squeeze through her pants. I was fairly confident that Stacy wouldn't be able to see, even if she looked back through the window.
"I have to shower. Want to join me?"
"I'd love that."
As Stacy's van pulled out of the driveway, Mom started toward the stairs. I followed, gazing lustfully at her ass. Feeling my eyes on her, she paused halfway up the stairs and bent at the waist, pressing her butt back at my face and shaking it slowly side to side.
"Is this what you want, baby? Some of this?" I pressed my face into her, eagerly awaiting the next few minutes when I would get to see this ass unclothed, in all of its plump and sexy glory.
"Yes, ma'am. Can I buttfuck you in the shower?"
"Mmm... so direct. But, no. Not yet." Mom continued her ascent of the stairs, turning left into the master bedroom. I followed obediently.
"You haven't seen the new shower I had put in, have you?" Mom asked once we were in the bedroom. The renovations had happened about three months ago, so it was all new to me.
"No, just the pictures you posted of it."
"I love it. Very spacious. But there's still one thing I haven't gotten to do in it yet." She grinned at me evilly, slowly sauntering towards me. "I haven't gotten my pussy stuffed by a big, thick cock in there yet."
"Mmm... one like this?" I smiled at Mom as I unzipped my pants and pulled down my boxers to reveal my erection. I had shaved the previous day in anticipation of my visit, so my eight inches was looking particularly glorious.
