“Mike, my mom needs you to change her smoke detector batteries,” my wife Holly told me.

It was the usual story. My monster-in-law needs something and I have to blow my Saturday morning to do it.

Holly’s dad died when she was in high school and Jane never remarried. I don’t think she ever dated anyone, at least it was never mentioned to me. It’s surprising because if you can get past the battle-ax personality, she’s an attractive woman.

“Fine,” I grumbled.

She kissed my cheek and said, “I’ll make it up to you later, baby.”

She would too. I always got a blowjob after helping her mom with something. My wife, while not being submissive to her mother, felt powerless to say no to her, even at almost forty.

It caused some issues in our relationship over the years, including my almost calling off the wedding when she wanted to control every aspect of the wedding down to my groomsmen’s shoes. Shoes for Christ’s sake. The woman was a control freak.

“I’ll head over there now. I’d rather not ruin my whole day.”

“Thanks, Mike. You’re the best.”

“Yeah, yeah, yeah.”

She berated me so much, I initially thought that Jane was racist and my being black and Holly being white was the cause of her hatred for me. Holly assured me that she wasn’t racist and she adores our twin girls with no outward signs of aversion to their skin color.


I walked the three blocks to Jane’s house in a fairly angry mood. I had to remind myself of the blowjob I’d be getting later, to help calm me.

Jane, my mother-in-law was standing on her porch when I got there.

“It’s about time, Mike. You’re going to make me late for my hair appointment.”

Yeah, I noticed she didn’t say hello to me too.

“Jane, it’s going to take half an hour to do the batteries. You know that from the last several times.”

“Yes, well get moving. Make sure to lock the door when you leave and don’t make a mess.”

“Oh, you’re not staying?” My morning just brightened. I wouldn’t have her snapping at me over every little thing from dirty ladder feet to not dusting the detectors.

“No. I told you I have a hair appointment. Start listening and you might learn something someday.”

I turned and walked around the house to get the ladders. Yes, ladders. She has a vaulted ceiling in her great room that needs a very tall ladder. That ladder is too tall to fit in the bedrooms, for which I need a shorter ladder to reach the detectors. Whoever designed her house must’ve hated their son-in-law too.

It occurred to me that I’d never been in her house alone. I had been there with just my wife, but never alone. A wicked grin crossed my lips when I decided to snoop around.


With all of the batteries changed, I put the ladders away and walked back into her bedroom. The first thing I did was open her nightstand drawer and I was shocked by what I found.

I wouldn’t have been surprised to find a vibrator in there, it was the butt plugs and anal beads that shocked me. Who knew she was kinky? I thought.

Like mother, like daughter. My wife and I did just about everything. She was a very sexual woman.

I found an iPad in there and guessed correctly that the passcode was Holly’s birthday. When the screen opened I was more shocked than before. PornHub was open and the scene was called: “White wife dominated by black bull.”

“Holy shit!” I said out loud and sat on the bed shocked.

I looked at her history and found that every video she watched featured a black man or men and a white woman. My mother-in-law masturbated to black men. Of course, I immediately wondered if that was because of me. Did she want me? Nah, there’s no way, I figured.

Then I opened a second tab which was on a pay-per-view site. Who pays for porn? The shit’s free all over the place. Anyway, I was floored by what she watched on that site: “Mommy, Me and a Gangster.”

Another holy shit moment for me. Not only did she watch interracial porn, but she also watched mother/daughter sharing interracial porn. I was stunned speechless.

I put everything back the way I found it and closed the drawer. I must’ve taken longer than I thought because I heard Jane return.

I quickly made sure everything was in its place and walked downstairs as calmly as I could.

“Oh! I didn’t expect you still here. Is there a problem?” She sneered.

“No. I was just making sure I didn’t leave a mess.”

She walked away ignoring my answer and I said, “Bye, Jane. Your hair looks nice,” as I walked out the door.

I couldn’t wait to get home and tell Holly what I found. I wondered if she’d be mad at me for snooping as I did, but I’d risk it. What I found was just too damn good to keep a secret.

I saw the girls’ car was gone and was glad. If my seventeen-year-olds were out, I might get my blowjob sooner rather than later.


“Honey, I’m home,” I shouted as I hurried through the door.

“Everything go okay?” She asked.

“Where are the girls?”

“Don’t you remember? They went up to Mickie’s parents’ lake house. They’re spending the night.”

I smiled, pulled her into my hip, and planted a deep kiss on her lips.

“Mm, baby!” She purred breaking the kiss. Save that for later. I’ve got some chicken salad made for lunch.

“Okay,” I said, “but I’m hitting that right after lunch.” I smiled and she kissed me.

“You’d better be. We haven’t had the house to ourselves in ages.”

I slapped her ass as she jiggled into the kitchen. “Oh! You’re never gonna believe what I found at your mom’s.”

“What’s that?”

“Anal sex toys, and...”

“What! She shrieked. Did you go snooping around?”

She didn’t look angry, but I knew I had to tread lightly.

“Yes, just a little.”

She was about to say something when I held up my finger.

“Baby, she had porn on her tablet.”

“Michael!” She gasped. “What the hell were you doing going into her tablet?”

“Baby, wait! It gets better.”

She glared at me, waiting for me to continue.

“She had interracial porn up.”

Her hand flew to her mouth in shock. “Get out?”

“Yep. Black guy dominating white girl stuff—and baby? She had mother/daughter doing black guys together porn.”

“Holy shit!” She practically screamed.

“Baby, I’m still shocked. Your mom gets off on incest and black and white porn.”

“Michael?”

I knew what she was going to ask before she said it.

“Do you think she wants you?”

“I doubt it. She hates my guts. I’m sure it’s a coincidence.”

She looked at me with that look that all wives develop after marriage. It’s a cross between “are you that stupid” and “give me a break”. You all know the one.

“Well, don’t you be fantasizing about her. Eat your sandwich,” she said with a sharp tone.

Just then the phone rang. Of course, it was Jane. She talked to her about seemingly nothing as I ate my sandwich. And then my wife frowned and looked at me.

She said, “Mom, the girls are gone today and we were gonna have some us time. Mike can take care of that for you tomorrow.”

Great! What the heck did she want me to do for her now?

“Mom, no. I told you...”

She was cut off and I could see her getting angry. She didn’t get angry with her mother. Frustrated sometimes, but never angry.

Sometimes, I regretted being so handy. I had been a union carpenter for twenty years. I could also work on cars if the repair was minor enough. Jane took advantage of that very regularly.

“Mom, enough! I’m not losing my rare day alone with my husband so he can do your brakes.”

Damn! I knew it would be something like that. I’d have to go to Auto Zone and get the caliper tool kit. What a pain in the ass. I bet she needs an oil change too.

“Oil change? Mom, no! Not today.”

I knew it. I was rooting for my wife on the inside. I was silently urging her to stand her ground. Just then I had an idea.

“Tell her we’re going to Galena to get some wine,” I whispered.

She smiled and said, “Mom, we’re going up to Galena to get some wine. It’ll just have to be tomorrow.”

Bam! Score one for the good guys.

“What wine? You know I like the Galena Cellars Port and the General’s Red.”

Then she frowned. Oh shit!

“When did you get that, Mom?” She asked worn down.

“Mom, can’t we just...”

Damn! Whatever Jane said ended the battle and it looked like I was going to Auto Zone.

“Fine!” She shouted and slammed the phone down.

She looked at me sadly and said, “I’m sorry, Mike. She has to drive her friends to Lake Geneva tomorrow and her brakes are squeaking.”

I shook my head, “Yeah, whatever. Let me go do some more work for the kinky freak that hates me.”

“Ugh! Don’t remind me of that,” she whined. “I’ll come with and run interference for you. Maybe she’ll leave you alone if I’m there. Besides, she has the wine I said we wanted. I forgot we gave her a case of each last time we got back from Galena.”

“Yeah, another failed attempt by me to get her to treat me better. Christ! You’d think she’d be intimidated by a 6’5” 250-pound guy?”

“Who’s got a body built for sin,” she laughed.

“And an appetite for passion. Come on let’s go to the parts store so we can get home faster.”


I had the car up on jack stands, the oil drained and the brakes finished. I’d been working for over an hour and a half and I was tired of being on my back on her hard driveway. I wasn’t a spring chicken anymore at thirty-eight.

I put the new filter on and lowered the car—and then I screwed up.

I had the oil container open on the driveway and as I backed up, I knocked it over. Just at that moment, the ladies walked outside with wine glasses in hand. Oil was pooling on her spotless concrete and Jane lost her shit.

“You careless jerk! Wipe that up immediately! I’d you’ve stained my driveway, I’ll...”

Jane was cut off in the middle of her screaming tirade by my angry wife.

“Shut up, Mother! It was an accident and cat litter will absorb it all up.”

I stood there shocked as Holly walked into the garage and grabbed a pail of cat litter. Jane said nothing as Holly set it next to me.

“There you go, Mike.”

“Uh, thanks,” I muttered as I poured it on the spot of oil.

Jane snapped out of her shock and shouted, If my driveway is stained, you’ll be...”

“Enough!” Holly shouted. “Get in the house now.”

I looked at Jane who meekly turned and walked towards the house.

“You too!” She shouted at me and then an evil grin crossed her lips. I wondered what the hell she was up to?
