I guided her to turn around.

Anna now sat on my lab with my cock in front of her. She continued to stroke me while I look at her chest jiggle in the rhythm of her accelerating movements. I put my hands on her hips and caressed her. Let myself feel up her curves, slipped my fingers under her waistband and grabbed her ass spreading her cheeks slightly. My right hand found it's way around her thigh to the front and between her legs again. Anna was still soaking wet and a shiver went down her spine when I started to play with her again. With her free hand she squeezed her own breast and moaned every time she breathed out. I was just about to cum all over when she slipped aside her slip to reveal what was underneath but I pulled her in close so she dropped onto of me.
I pulled my cock out underneath her, gave her a kiss and stroked myself over the edge. I came all over her back and ass. I don't think it has ever been this much. I let go of myself and pulled her in closer for more kisses.
She smiled at me. Stood up and turned around.
"Quite a mess you made.", she winked.
"I think it's more your fault than mine but okay. Do you need a tissue?"
"Honey, I think I need a shower and new underwear. You soaked these with your cum."
I stood up and headed towards the bathroom.
"I can offer a shower but sadly I don't have any fitting panties for you."
I said it with an obviously acted sad tone, as I held open the door to the bathroom. She walked past me and into the shower cabin.
