Give her what she wants

"O.k." I said "Lean against the wall”

Tracy did as ordered and I walked over and checked out her fine ass. I could see the outline of her underwear through her shorts. I roughly pulled her shorts down to reveal a pair of white cotton panties.

“What’s this?” I said “I thought I told you. G-string, C-string, or nothing!”

“I – I’m sorry.” Tracy stammered “I - I forgot”

“Maybe we should just forget this” I said cruelly

“NO!” P-Please John! Please!” cried Tracy desperately “I’ll remember next time. I promise. Don’t go?”

“O.k.” I said “I’ll give you one more chance, but no more.”

“T-Thank you. Thank you” Tracy almost sobbed.

I reached out and pulled, first her shorts then her panties down to her ankles, kneeling down to get a better look at her ass and her pussy, its lips already puckered and moist. I breathed in the scent of her, a pungent mixture of sweat and desire, before standing up.

I drew back and slapped her ass.

“AH!” she yelped

“That’s for forgetting!” I said the slapped her other cheek

“AH! What was that for?” she complained

“To even you up” I said “I like symmetry”

I reached up under Tracy’s shirt and felt, as expected, the back of her sports-bra. I quickly unlatched it (after the fiddling I’d done with wires, etc. in the lab a bra was easy.)

I then reached around and gave Tracy’s newly liberated breasts a gentle squeeze causing her to purr in appreciation.

I quickly undid my pants and pulled out my already painfully hard erection then, separating Tracy’s thighs with my hands, I placed the tip at her entrance. I felt its warmth and moisture inviting me in.

“Ready?” I asked, somewhat redundantly.

“Yessss” Tracy hissed.

I pushed the head of my manhood between her fold then let go of Tracy’s thighs, grabbed her waist and pulled her toward me, burying myself deep within her. She groaned and almost forgot to keep her hold on the wall as she stood unsteadily on her blades.

The feeling of Tracy’s pussy was unbelievable. She was so wet, warm and tight, and the noises of pleasure she made simply drove me on. I pulled back and then thrust into her once more. Over and over, until finally I could hold on no longer and I spilled my seed deep inside her. As I did she cried out and her body convulsed and then shivered as the pleasure of the orgasm I had told her she would have wracked her body. I had to grab her tight and hold on to stop her toppling us both over forward into the wall.

Finally her body went limp and I withdrew.
