Relax

You relax. Clearly she just wants to show her appreciation and considering how excited you are about the whole situation. You don't think it's a bad thing. Marissa pulls your bed sheets down until they're below your hips and rubs you gently through your underwear. "My, aren't we well endowed" she slides your underwear down and strokes your cock with her hand.

You stay relaxed and let her take control. the scandalous feeling of being so intimate with a married woman and a pretty one at that sends chills down your spine. She smiles at you and pulls her nightie off. Her already attractive body is augmented in the pale blue moonlight. Her round breasts and stiff nipples all the way to the shadows between her legs. She moves overtop of your rigid rod and you feel her entrance against the head of your cock. It isn't long before she slides your manhood into her. Your whole body tingles at the feeling of being inside her vagina and she moans gently and keeps pushing you deeper into her until she returns to being rested on your lap. Your cock fully hilted inside her.

You feel her vaginal muscles squeeze the length of your cock as she starts gyrating her hips. She rides you slowly, her breasts jiggling a little. She pushes her hands against your chest and leans against you for support. You reach up and cup her breasts. They're a nice handful and you pinch her nipples that have been stiffened by the cool evening air. She moans a little more from you stimulating her nipples and she keeps looking down at you, a pleasured look on her face.

The sex is mostly quiet, but the cool moonlight stimulating your eyes, the way Marissa is looking down at you, and the feeling of her womanhood around your cock makes your whole body feel charged. She moves her hips more quickly, her body burning with her own desire as she closes her eyes and concentrates on the pleasure. You feel her body stiffen in your hands and around your cock as she has a gentle orgasm. Her vaginal wall massaging your cock.

Your own climax builds as her vagina spasms around your cock and you stiffen your body in preparation, "Marissa...I'm gonna..."

"ssh..." she responds, "Just let it all out." there's little you can do as she squeezes you tightly to send you over the edge. It feels like explosions of pleasure are going off in your head as your orgasm washes over you. You thrust your cock up as it starts to twitch and throb inside the countess and you feel your seed flooding into her. She tilts her head up and opens her mouth a little as she pushes down against your thrust and she feels your warmth filling her.

You both relax with her laying against you. your cock continuing to twitch weakly inside of her. She looks up at you and kisses you on the lips gently, her hand sliding against the stubble on your face. Then just as quietly as she entered, she slides off your cock and pulls her nightie on and leaves.
