Seems like you have to

Stacey swiveled around in my lap to face the now-locked door, grinding her ass up against my cock and moving my hand to hold her soft, enormous tit. I played with her giant nipple as she bent over to pull her large, lacey panties down. Her nipple was pointy and she was clearly turned on. And actually, I hadn't gotten any softer, either. Her ass kept grinding up against my dick and I had to admit it felt pretty good. She pulled my other free hand down towards her crotch, and repeated "No penetration... If you insist." She was soaking wet, and had clearly shaved recently with a thin landing strip pointing towards her gushing pussy. She guided my fingers towards her large clit. As we moved together, I noticed just how soft her entire body felt. I pressed my fingers down.

She jerked up and clasped her hands over her mouth, crushing my hand into her breast, barely stifling a shrieked "Oh fuck!" She turned to look at me with an expression of almost painful longing. She ground even harder against me. I kept going, and she led my hands up to grope her massive tits.

They felt amazing, but I knew I had a job to do to get out of this mess. I returned my fingers down below, and she began moaning. "Fuck fuck please... Omigod fuck me don't stop please fuck..." Her entire body began rippling as I played with her. I stuck some of my fingers inside her, breaking my "no penetration" rule a bit, but it was only fingers, right? And it seemed like she really needed it. We kept going as she let out moans and squeaks of pleasure, gyrating and losing herself in my lap; I'd never been with someone so vocal and so sensitive.

When she finally came it was explosive. She jerked forward and strained against my hand, letting out guttural, animalistic moans as she clasped her hands over her mouth again to stifle the noise. She was still loud, half roaring and half crying. She slapped her ass up and down against my legs, trying to both escape and prolong the pleasure.

Finally she came down, and slowly slipped to the floor. She turned around and looked up reverently, reaching up to begin slowly stroking my dick again. She freed her large, sagging tits from her bra and dress, giving me a long eyeful. "Thank you, John... That was amazing. I haven't felt like that in a long time."

I just sort of smiled, not sure what to say or do.

"I really, really want you inside me," she followed up, with a slight tremor.
