Assfuck her

I cease fucking her and slide my cock out of her snatch, a trail of pussy juice linking the tip of my cock to her wet pussy lips. Stacey's puckered asshole looks so inviting and I can't resist.

"What are you doing?" she asks as I prod her asshole with the head of my cock.
"What do you think?"
"I...I've never done that before," she pleads.
"Well there's a first time for everything," I reply, her pleading actually turning me on even more.
"Please..." she begs.

There's no way I can hold back now, though. I hear a sharp intake of breath from her as I penetrate her anal sphincter with my cockhead, and the feeling is unbelievable as I slowly push my cock inch by inch into her incredibly tight arsehole.

I grab her by the hair and pull her head back as I sodomize her right there on the stairs.

"I bet you love it...tell me you love it"
"I love it" she moans.
"What do you love?"
"I love your big...hard cock...up my tight arsehole"

With that I know I can't last much longer, and I savor those last few seconds, knowing I'm about to nut.
