Unexpected Anniversary Gift

We've been together ten years. I couldn't imagine what sexual play my spouse will let me do with her long hanging tits to get me off. I had to be satisfied with abusing those hangers in place of not getting oral from her. I was laying in bed playing with my shaft expecting she'll come into the room swinging her tits or them being roped and giving me a tit job.
She entered the room dressed in a dom outfit holding a whip , having her tits exposed and hanging over her new outfit. She dangled her hot tits in my face and gently whipped my erection saying, "Your tenth anniversary g*ft for staying with me." I told her I was surprised and she told me there's more. She blurted out, "You can come in now!" It was my chunky sister-in-law totally naked exposing her small breasts with hot nipples covered with freckles and her hairy red haired snatch.
My spouse gently tapped her sister's big ass with the whip and told her to give me a blow job while she watches. As her sister was giving a blow job, my spouse tapped my nipples and told me to put her tits in my mouth. "Make believe it's me sucking that dick ! " my spouse said. "Now pretend you're eating my hairy dark brunette kitty ! " I was eating out her sister's c**t and my spouse watched as she jerked me off and ordered her sister to play with her nipples pretending she was her. I reached my arms up and started feeling and pulling those nipples. I wanted my spouse to lick her sister's hot freckled tits as I played and sucked on my spouse's handing breasts.
The next day my spouse told me she's ok with her sister and me having oral sex only but nothing else, otherwise she'll never wear that new dom outfit.
