Eventually, she stops you

"FUCK...those fingers feel good..." Meredith hissed, wanting to stop you before you tried to put your dick inside of her, but the feeling of your fingers grazing her cunt felt to good for her to do it right now.

"You like that honey? Stick with me and you can have it all," you whisper to her, using your position of power in hopes she will give in and go all the way with you.

"UH. I want to stop you, but it feels too good," she moaned as you pulled her panties to the side and slide three fingers up her married snatch, beginning to rhythmically thrust in and out of her as she arched her back and pushed her hips into your invading digits.

"I want to fuck you Mere," you whisper to her as you bend her over the desk, hiking up her dress and dropping your pants as you started going in for the kill.

"Stop...John...stop. You know I'm married, so I cant let you put it inside me," Meredith whispered as she heard your pants dropping and felt your dick running along her pussy lips, finally remembering her husband and her marriage as she pushed you away.

You're pretty sure if you had pushed into her and gotten a few thrusts in that she wouldn't have stopped you from completing your mission of spreading your seed inside of her, but you decide to play it safe and back away from her as she gathers herself and starts to get ready to head home.

"Maybe you'd like to suck it instead Meredith? Oral sex isn't REALLY cheating, you know," you ask her as you kiss her again, Meredith melting into your kiss again as you pushed her to her knees.
