Isabella absent-mindedly worked away at cleaning the dishes, humming along to whatever white girl music of the month enthralled her. I can't stand the music she likes, but it wasn't too bad though because I enjoyed how she swayed her juicy hips back and forth with the song. She was in a lazy Sunday kind of outfit, one you'd only wear around at home: An oversized t-shirt that said 'I'm not fat, I just have big boobs' over her huge cow tits and only panties underneath that I could get glimpses of whenever she bent forward a little too much while doing chores. Even better, the summer heat made her sweaty, which mixed with her perfume to make a smell I could only describe as sweet muskiness. It's hard for me to think about anything else when Isabella is wearing this particular scent... God, this effect she had on me is exactly why I started dating her. She was so innocent, but her body was one of a completely slutty woman. I knew I had to act, and I had a plan. Today was April Fools' Day, which meant an opportunity for my usual antics with her. I crept closer to her from behind, her humming growing louder as I drew near. Finally, my time to strike.

"April Fools!" I announced, making her jump as one of my hands slid past her arm, firmly grasping onto one of those huge breasts. My other hand went under her shirt to her tummy, squeezing and rubbing its softness through her thin cotton fabric.

She gasped in surprise at the sudden touch, and looked towards me with pouty confusion. "Why are you doing that?" She asked, looking down at my hand, still playing with one of her boobs over her t-shirt.

"It's April Fools, you dumb cow." I answered back, trying to hide my excitement. "This is just what couples do on this day. Don't you know how this works? You don't have any idea what's going on..."

She was starting to get distracted by my groping and kneading, but tried her best to continue the conversation. "Ah! I don't really-ugh- know how this... April Fools... works... but if this is how it is then go ahead... uhhh..." Her voice died off in midsentence, as she endured my unrelenting groping. She had put down the dishes, and now looked upwards with a look of mixed confusion and arousal.

I didn't let up at all; instead I just kept tugging at her breast, causing her to wobble her shoulders in ecstasy. I moved from rubbing her stomach to running my hand along her sweaty inner thigh, feeling the heat coming from her body. Her breathing turned labored, as did her moaning, but she remained silent otherwise. This was where I stopped my antics to ask her something.

"Do you like these kind of jokes, Isabella?"

"Y-Y-Yeah?" Isabella stammered out, blushing furiously. The way she looked down demurely caused another thrill run through me. "Jokes are always fun, even if I don't understand them all the time..." She added sheepishly.

"That's okay. Whenever you're confused, I'll be there for you, and explain everything to you."

She gave me an endearing half-witted smile. "Thanks... What does that mean for today?"

"Well, you see..." I leaned in close to Isabella, my lips inches from her ear. My hand toyed with her left nipple as I whispered into her ear, "on April Fools, I have to grope you, and you're supposed to try to pretend its not happening. Got it?"

She nodded slowly, taking my word for it without hesitation. "Seems like a weird tradition, but sure, I can do that..."

I finally ended my groping, and pulled my hand away from her boob. I glanced up at her face, seeing her mouth hang open slightly. All that touching really put her in a daze, which suited her perfectly. I turned to walk away, planning my next groping attack. "Final thing! No masturbation!" I called from behind, giving her no chance to respond before walking further into the house.

I heard her muttering in thought behind me.

"This holiday even has rules about masturbating, huh..."

I had waited a few hours, before checking up on Isabella again. And luckily for me, she was in the perfect situation for a little more fun. I found her in the living room,
