I was at home early from school and always horny.  I had spied on my mom several times and masturbated to her nude body.  She has enormous tits  (44EEE)  And I love big tits, so I spent a lot of my youth hard for my mom.  I was always trying to hide my boner around her.  Anyway, since I was home early and no one was home, I had one of her bras in my room and I was nude and stroking to her bra, imagining her big saggy tits.  I also had several big titty mags laid out on my bed and floor to help my imagination.  I could cum multiple times as a young man and had already blown a load on my mom's bra and was starting up again, hard and having fun.  I didn't hear my mom come home because I was so focused on my fantasy.  She heard me and walked into my room while I was stroking.  Her bra was covered in my cum from the first time and laying on my bed.

"David, what the hell are you doing?"

 "Uh, Mom..."  trying to cover up, but clearly busted....  "Just, uh, you know...  guy stuff..."  I looked down and started trying to gather up my mags, ignoring the bra and hoping she wouldn't notice.  She came in and grabbed my arm, stopping me.

"You horny little fuck!  Where did you get all these?"  She was trying to sound mad, but she looked down at my hard cock and didn't seem to be as mad as I thought she would be.

"I just bought a few.  I'm sorry, mom.  I'll get rid of them."  I was still hard and didn't think she had noticed her bra.  "Can I get dressed now?"

Mom looked at me and smiled.  "NO!  First, I want you to explain this."  She reached down and picked up her bra.  "Why is this in here?  And why is it wet?"  She rubbed her fingers in the cum and clearly knew what had happened.

"Well..."  I looked down, knowing it was useless to lie...  "I really like your bras, mom.  They make me hard.  I’m so sorry, mom.  Please don’t be mad at me.  I’ll clean everything up.”  She still held my arm, but loosened her grip.

“David, honey…  I’m not mad at you.”  She released my arm and smiled at me.  “I understand a young man’s needs.  But, you need to be completely honest with me.  I don’t want to get your dad involved, but if you’re not being honest…”  She trailed off, looking down at my hard cock and then back in my eyes.

I was panicked at the mention of dad.  He would kill me!  I knew I needed to be completely honest or mom would know I was lying.  “Okay, mom.  But, please don’t be mad.  And, please don’t say anything to dad.”  She smiled at me, nodded, and rubbing my shoulder.   “I’m just horny all the time, mom.  And…  I …  love big tits.  And, I really love yours.  I buy all these mags and try to find other tits that look like yours.  I’m so sorry, mom, but I can’t help it.”  Her reaction to what I said was totally unexpected.

“Honey, it’s okay.  That’s really sweet of you to say that.  But, how do you know what mom’s tits look like?”  She smirked a little, her hand still on my shoulder.

I could tell she already knew, but was going to make me to say it.  “Well, mom, sometimes I spy on you when you’re in the shower and dressing.   Please don’t tell dad.”  I was sweating, but still hard.  I secretly felt excited and relieved telling mom the truth.

“Hmmm…”  She looked down at all my magazines and then at my cock before looking me in the eyes again.  “Well, it can be our secret if you promise to get rid of all these mags.  Deal?”

I smiled, relieved.  “Deal!  No problem, mom.  I’ll get rid of them now.”  I started to gather them up, but mom stopped me.

“Just a minute, mister.  I’m not done with you yet.”  She smiled at me.  “Close them and stack them all up.  Then I want you to do something for me so that I know you’re not lying.”

“Uh, okay, mom.   I’ll do whatever you want.”  I had no idea what she had planned, but I was just happy she wasn’t planning to tell dad.  I stacked them all in a nest pile and waited for her direction.

“Good, honey.  Now….  I want you to stroke for mommy.”

“WHAT!?”  I nearly collapsed in disbelief.  “But, mom…  I mean…  what?”

“I want to believe you, honey when you say these mags only reminded you of me, but you need to prove it to me.  Otherwise, I might need to tell dad.”  She could see I was listening closely at the mention of dad.  “So here’s the deal.  Get rid of the mags and cum for these.”  She unbuttoned her top and slipped off her bra revealing her huge tits just inches from my face.  My eyes were wide and dick was ready to explode.

I could barely speak, trembling with excitement.  I couldn’t believe my mom was standing there letting me see her tits up close.  I completely ignored the stupid mags and totally focused on mom’s tits.  “Mom, your tits are so perfect!  I won’t last long.” 

Mom smiled squeezing her tits for me.  “Call me mommy.   Tell me you want to cum for mommy’s tits.”  Then she gave one of her big thick nipples a little tug.

I was so hard and horny I would have said or done anything.  “I love you mommy!   I really want to cum for my mommy’s tits!”  True to my word, I only stroked a few times before blowing my second load that day.  It felt so good having my mom watch me cum.  It was so intense.

“Hmmm… “  She smiled big at me, still displaying her massive tits.  “Your secret is safe with me, honey.  I can see you were telling me the truth.  So, I’m not even the least bit mad.  But, I don’t want to see these mags around here anymore.  Okay.” 

“I promise you’ll never see them again, mommy.”  It felt a little weird calling her mommy, but I didn’t mind too much.
