Wife Starting To Pretend

After months and months of telling my wife about my desire of being cuckolded, asking her to fulfill my passion, she surprised one night. We were going to bed like a normal night and she leaned over and asked we i wanted to have sex. I immediately said yes as I started to remove the covers to find her laying in bed without pj bottoms and a clean shaved pussy. I slowly started to kiss her inner tights working my way up towards her freshly shaven pussy as she grabbed my hair and pulled me up towards her mouth and he kissed me. She then said she needs my cock inside her. I easily slid my cock inside he making this last as long as possible when she wrapped her legs tight around me, digging her nails into my beck pulling me into her with every thrust knowing i was about to fill her pussy with my cum. Moments after my ejaculation I fell onto to the bed and she rolled towards me and kissed me passionately on the lips and asked if i could handle not cumming unless i really could have self control. I said i have complete control and she said good that a commitment and reached over and laid a purple mini vice chastity cage on my chest. She watched me install it and she pushed the lock tight till i heard the snap. She said from now on every time I ask, talk or complain about the chastity device or anything about it, one more day i am locked up without orgasm. She said tomorrow is one day and she will unlock me if i pass the test. I smiled and said this will be easy. She smirked back at me, she lifted her leg to expose her cum filled pussy and told me she wants to reach another orgasm with only my tongue. I hesitated at first until she grabbed my head and forced it towards her dripping pussy. I licked my cum and her cum for what seemed like forever until she wrapped her legs so tight around my head as she organised and pushed more cum into my mouth. She tasted wonderful i finished my task and covered her up with the hopes to be unlocked in the morning but the desire to be locked for ever.
