She smiles and tells you she doesn't want to hurt you. But the connection with him has become real. Because of that the sex with him is even more amazing. Even without that connection his big cock can quickly bring her to orgasm. With that emotional connection though her body flows in orgasms, her pussy drips, her body and mind constantly desire him.
She hints at an out for you. Your sweet wife telling you "I don't want to hurt you." She has seen how her love for another man effects you. How it hurts you, causes you shame, fear of losing her and even more inadequate than you felt as just a cuckold when she was just having casual sex. She doesn't want to stop but she gives you a chance to end it.
In you mind, you want to tell her to stop. Your mind tells you this is not a good idea. That it is going to crush you. She sees the turmoil in your eyes as she rubs her body on your dick.
She feels your hardness because at the same time you are fantasying in your head her fucking him, her staying the night with him, waking up and making love with him. You want to slide your dick in her pussy but there is also a voice that is telling you. "Wouldn't it be hot if she saved her pussy for him."
She slides it insider her. It feels great, warm, wet, pleasurable. You slide it out and rub it against her clit. You can't help yourself... you tell her "It does hurt you love him, but i'm also thinking it would be hot if you saved your pussy just for him."
She smiles. It is dark and twisted but that turns her on. She has a wicked smile and a giggle. "Yeah, you would like that, my pussy only being for him?"
You moan as your dick rubs on her pussy. Not a grunt like her boyfriend makes when he drives his big cock inside her. A moan like a submissive sissy.
The conversation has you on the brink of a more pleasurable orgasm than you can ever have inside her and you gasp and tell her. "I'm not sure if it is what I truly want but it would be hot." A typical answer from a submissive male, you need her to deny you, to lead.
"I can't wait to fuck him, spend the weekend with him, wake up and make love to him." She talks dirty to you. Her orgasm building as your dick rubs her clit.
At the same time you both shake in pleasure. Your dick spurting cum across your stomach and her pussy becomes drenched with her own juices as you both gasp and orgasm together in the fantasy of her with him.
She gets up and walks to the bathroom, smiles at you and says "You are so hot."
