We continue to have sex even when my wife has a lover. The frequency drops significantly but, it is important to her to keep that special bond that having sex produces. I did tell her that if she wanted to be exclusive to her lover then I could live with that. She said that there may be times when she just doesn’t have the urge to be intimate with me but over the long term she didn’t want complete abstinence between us.
My wife allows me to masturbate and on occasion she will allow me to do it in bed next to her. That is the extent of our sex life now. I must enjoy it since i have no desire to leave or change our arrangement, i have simply accepted that it takes more than just me to keep her satisfied in all of her needs.

My wife likes it with her lover sitting, her on his lap with her back to him, makes it easy for me. We also have done it with her on her back and her lover sitting on his knees with her kind of supported like that, has her pretty open. In some ways we find her being done doggy the hottest, I am very aware of her lover, his balls hitting me and due to it not being easy for me to lick her in that position and all, including my tongue touching his cock at times. I am very aware of her lover and his cock and my wife enjoys gently teasing me about my tongue on her lover’s cock.
We too indulge in this, my husband absolutely loves it as do I. One thing we have found is that if you lay on your side with the bull fucking you from behind it gives the cuck better access to pussy and cock. We found that after fucking in the doggy position with me straddling his face, he couldn’t get as much access as we would like. Far more area for him to clean while I’m getting fucked.
