There was an immediate response, and Susan felt her cunt twitch, getting wet quickly. She began to cry with shame, not wanting this, yet knowing she d...d.In a last minute attempt to stop this sin against nature--incest between a mother and her own son; Susan looked at her oldest son with teardrops falling out of her big beautiful baby blue eyes and pleaded again with him with what she thought was the most powerful argument for Mark to stop what he was about to do."Please Mark stops. You can't. Her perfect V-shaped pussy slightly poking through looking so juicy. I couldnt stop staring at it, I wanted to eat it so bad. As I move towards to kiss her, our eyes lock. I move my right hand onto her upper right leg, just inches away from her phat pussy. I put my lips on hers and we start kissing very deeply. I stick my tongue in her mouth then she sticks hers in mine. I go to put mine in her mouth again and as I do, I reach up to her pussy and start rubbing it as we kiss. She lets out some. I don't think that was enough. I think you need another smack. Hard! Leaving a big red mark the size of my large hands, how does that feel, slut? Being used and smacked and spanked? Is that punishment enough for you? I don't think so...I think you need another smack and another, each one pushing your body across that desk just a little bit, your erect nipples rubbing against your shirt, the desk, pinned underneath your body, another smack and another! My hand pinning you down against that desk,. But now, he stops.And raises the hem of his robe, to reveal a long, thin erection.And the other two grab her, one on either side, a hand on her back, another on the back of her thighs, and lift her, legs spread, impaling her on the tall, slender cock.And he folds his arms around her body as they leave go.And there they are, dancing in the moonlight as he fucks her in time to the waltz.And she feels a combination of discomfort, of pressure, but of sexual warmth as well, as he fucks her and they.
