It was my freshman year in college when my life changed with my Mother, and I was twenty years old at the time. What I meant by a change is that's when I first discovered I actually craved for my Mother in a sexual way.

I know, right. I was amazed at first myself to have these unthinkable ideas swimming around in my brain about my Mother, but in my defense, it was really her fault it happened - at least that's what I told myself.

I guess I should take you back to when it all started.  It was a weekend night, and like every typical weekend, my girlfriend Becky came over to my house to visit me for a while.

Usually, that consisted of us sitting around the living room with my parents watching the television.  Until it became very late, and my parents would excuse themselves to head to their bedroom, leaving Becky and me downstairs on the couch.

Typically after waiting for about a half-hour to make sure my parents were asleep, we would start to fool around on the couch, doing nothing special - just some petting and kissing. Only Becky had other ideas tonight.

Becky, my girlfriend, and I had been dating since the beginning of college when we met in a science class and hit it right off. As it turns out, over the course of a couple of months, I quickly found out that Becky liked having sex as much as I did. But, to tell you the truth, I don't know who is kinkier as you'll see.

Because tonight as we kissed and lightly caressed each other, Becky suddenly broke the kiss and whispered, "Tommy, do you have any porn we could watch?"

"What? Are you crazy? My parents are right upstairs!"

"Shhh," she said, holding a finger to my lips while exhibiting a devilish grin. "That just makes it more exciting."

My semi-hard-on went to a full throbber when she said that. Only I didn't have any movies per se in the house, but there was always the internet. Lifting my body from the sofa, I went quietly to my room and grabbed my laptop. Hooking up the video port to the TV, I scanned for a porn site on the PC and in no time had found one that streamed lots of sex videos and picked a couple for us to watch.

It wasn't long before the explicit scene we were watching soon began to affect both of us, causing Becky to settle in closer to me before she rubbed her hand over my crotch while I worked my hand between her legs and brushed it against the material covering her mound.

This was so very erotic but scary at the same time, not knowing what my parents would do if they caught us like this.

So as we watched our little porn movie, my ears listened to every noise while my eyes every once in a while would glance over at a mirror that viewed the stair landing behind us since I figured I would surely see a light come on if one of them happened to come down and investigate.

By the second movie, we were really hot and had our hands inside each other's pants while we were panting like dogs. God, I just loved how my fingers dabbled with her pussy and clit, while she jerked my dick up and down, causing my dick to drip tiny amounts of precum.

In my excitement, I had forgotten all about glancing at the mirror because my eyes were glued to the screen watching a tall, dark stud with a 10-inch cock bang the shit out of a drop-dead gorgeous blonde.

"Oh fuck..." I groaned in sexual delight when my sperm quickly built from the pleasure Becky was giving me, and I slipped my fingers into her wet pussy, hoping it would help her climax alongside me.

But just as I felt myself ready to explode, I caught movement in the mirror. My eyes quickly peered into the darkened reflection, and I felt my heart stop when I realized it was my Mother sitting on the landing in her red satin robe just watching us.

Okay, I wasn't sure if she was watching us or the sex act that played on the family tube, but she was watching, just the same.

My hand froze inside Becky's snatch as I pondered over what to do. Should we stop what we were doing and tell Mom we were sorry? I wasn't sure, and my mind went into a panic, and as a result, I could only watch my Mother in the mirror while Becky kept jerking me off.

Only as I kept my eye on Mom, I noticed she hadn't moved an inch. In fact, as she sat there, it appeared as if she was totally absorbed in what we were doing. Strangely, that notion caused this sinful erotic excitement to surface inside me. This was definitely something new and exciting, and I couldn't believe how it was affecting me.

Then when I felt my cock begin to boil as this unthinkable lust rushed in my veins from my Mom seeing us this way, I heaved up off the couch while working my fingers deeper and harder into Becky's sweet pussy.

"Oh... Shit... Oh, shit!  Oh fffuck, B...B...Becky!" I groaned as my cum started to squirt. I closed my eyes and pushed my cock deeper into Becky's palm, causing my fingers to stiffen as they stabbed into her wet, swollen pussy. That's when I felt Becky rock on my hand, and her cunt gripped my fingers.

"Oh... Oh... Yes... I'm cumming too!" she said as her pussy gripped my fingers. Then, panting loudly as we both came back down from our mutual climax, I reflected on how hard I had just come from Mom watching us. Only as I slowly opened my eyes and shifted my vision to the mirror once more, I noticed my Mother was already gone.

Lifting myself forward, I turned off the laptop and, even though my pants were drenched with cum, we necked some more, giving me time to think if I should tell Becky about Mom or not.

Truthfully, I wasn't sure how she would respond to what I had seen or what she would think about me for not telling her when I noticed Mom, so I decided to keep it to myself.

After we fixed our clothes, I walked Becky home, then returned to the family room, unhooked the TV cables, and grabbed the laptop.

Quietly as I could, I crept to my room before crashing on my bed and just lay there thinking over and over again how exciting the evening was.

My mind wandered back to seeing Mom watching us, and whether I wanted to or not, I couldn't help but wonder if it would ever happen again and sinfully found myself wishing for it.

The following weekend, I was more prepared and had downloaded some scorching porn and saved it on the laptop. I wasn't sure how Becky felt about girl/girl stuff, but I figured this was the best way to find out.

Again, at around 11 o'clock, when Mom and Dad went up to bed. I told Becky I had gotten some new videos for us, and she seemed happy about it. We waited about an hour before I pulled my laptop out from under the sofa to set everything up again. Then I turned off all the lights and settled in next to Becky.

The first video we watched was your typical boy/girl theme with lots of sucking, licking, and fucking. It was nothing too raunchy, but as it unfolded, I kept a close eye on the mirror for any sign of Mom. Unfortunately, there was none.

But now it was time for the second video, and I felt a bit shaky as it started to play, keeping my eyes on Becky to see how she would react when she saw what kind of flick it was.

Steadily, I opened Becky's jeans and slid my fingers between her legs when the two girls began to make out. Becky's eyes widened as the scene unfolded, and I felt her getting moist to the touch. I wasn't sure if it was from my tickling her clit or from what she saw on the screen, but she was definitely getting hot, whatever the reason.

"You guys like this stuff, don't you?" Becky said while her eyes stayed glued to the screen.

"Don't you? I thought all girls have a little lesbian in them. At least, that's what I heard."

"Who told you that?" Becky responded, turning her head while giving me a puzzled look.

"Just the guys."

"Well, I don't know about that," she said. "I mean, I never wanted to lick any of my girlfriend's pussies."

"C'mon... never?" I said, "You never thought what it might be like to have a girl work her tongue around your mound? Or lick all your juices while you pushed her head down and rubbed your pussy against her face?"

She paused for a moment before turning her head back towards the screen and watched as the two women rubbed one another's breast with their hands.

"Well... I said I didn't want to do that to another girl," Becky hissed as she unzipped my pants and pulled my cock out. "But never said I wasn't interested in what it might be like to have it done to me."

I was so engrossed with our lesbian talk that I missed what I was initially waiting for. Mom had appeared again and was sitting quietly on the landing in her robe.

I felt my dick jump in Becky's hand as the rush of excitement grew. Knowing Mom was again present, watching from a distance, really affected me, and I felt my dark side emerging, wanting to take more chances.

The thought of Mom watching us again had made me so lustful I wanted to step it up from the time before. So as the girls kissed and fingered one another on the television, I worked my fingers into Becky.

In a voice I felt confident would travel to the stairs, I began some erotic talk and said, "So... why don't you imagine that the girl on the screen is doing this to you?"

Becky's body responded sexually as I moved my fingers in sync with what the girls were doing while the look on her face showed me how much she was enjoying what I was doing, and I barked, "She's going to make her girlfriend cum on her hand."

"Ohh... Tommy."

"Shhh... There's no Tommy here," I said as I pulled her hand away from my dick, "There are just us girls."

Becky's eyes were glued to the screen as the girls toyed with their twats while I shifted my eyes back and forth from the screen to the mirror. Mom seemed to be engrossed, but I couldn't tell from what until I caught her moving around and sinfully realized her robe had opened slightly, and the flesh between her breasts was now visible to my eyes. Only as I gazed at her beautiful melons, Mom's hand dug inside her robe, and I swallowed hard when she started to rub her tits!

Seeing that got me super excited, and I tugged at Becky's shirt, pulling it up and off her body, and paused for a second when her luscious globes were staring at me.

Of course. I thought, realizing my naughty girlfriend wasn't wearing a bra, and it only added to the sexual tension that filled the air. Quickly, I lowered my head down and sucked the closest soft nipple into my mouth.

"Ohh..." was all she could say as I flickered my tongue over it until it was nice and hard.

The girls on the screen were really getting into it now. One was at the other's pussy, lapping away, causing the other to moan loudly while she held the girl's head hard to her pussy and ground her box into the girl's face, and I croaked, "I bet you'd like to feel your girlfriend licking your pussy now, don't you?"

"Oh... Yes. Please lick my pussy."

Hastily, I eased Becky's jeans down past her knees and slid to her mound. I knew there was no way I could see Mom from there, but I was sure she would know what I was doing if she was watching us.

Pushing my head between Becky's legs, I began to lick her folds and was happy when her hands went to my head and guided me towards her clit. Slowly, Becky's hips twitched up and down as I worked my tongue in between her folds and began to toy with her little bud and heard her sigh, "Oh yes, honey. Mmm. Keep doing that. My god, your tongue feels so good. I can't believe I'm letting my girlfriend lick me like this."

My cock had never felt so hard before. Her pussy was drenched, and she just kept getting wetter and wetter. I could hear the girls on the TV loudly moaning and grunting as one announced she was cumming. The other girl egged her on, yelling, "Cum for me! Cum for me!"

Becky ground her pussy to my face, and I dug my tongue deep into her soaked snatch.

 "Oh... Oh... Yes... That's it... I can't believe it. This is so bad, but it feels too good to stop. Fuck, you're doing it. You're really going to do it. Oh shit! Oh shit! I can't help it! God help me! Fuck! I'm coming! I'm really coming! I'm coming on my girlfriend's tongue!!!" She whimpered as her body quivered out of control. I sucked and sucked, trying to get all her juices.

I had never felt her so wet. Her body convulsed on my face as she pulled me tightly to her mound. I almost couldn't breathe as she smothered me with her pussy and moaned, "Yes! God, yes! Keep sucking! Oh, fuck! Keep sucking!"

With her hand holding me tight to her pussy while she gyrated it over my face, I had to pull myself away, and I fell backward, catching myself with my hands behind me.

With my ass planted on the floor, now away from the couch, I had a clear view of the landing and caught my Mother's leg disappearing quickly up the stairs.

Becky's half-open eyes seemed glassy, and she had a contented look on her face when she called me back to her.

With a smile on my face, I crawled over and up her body, and we wildly kissed while her hand snaked down my body before stroking my dick.

I guess Becky felt it was now her turn to get me excited like never before, and she cooed, "Tommy... That was fantastic. It was like you were the girl doing me. I was so fucking hot."

"Yes, I could tell."

"Did that excite you? Seeing me so hot and wet," she said as she gripped my dick.

"Yes... Yes, it did."

And when she hissed, "Would you like to see me getting eaten by another girl?" I was flabbergasted. I didn't know how to respond to that question, but my dick did, and Becky went on, "Oh... You're so fucking hard now. I guess you do. You want to see me cum on another girl's face, don't you?"

I could only grunt as she worked harder on my steel rod and pleaded, "Tell me truthfully, Tommy."

"Yesss..." was all I could say as I felt the load building in my cock.

"So... just me getting licked to an orgasm? Or me doing a girl also."

"B..B...Both. Ohhh." I said as the vision of Becky going down on a girl wickedly filled my brain.

"You want to see me kissing her and feeling her breasts as I slowly inch my way down her body, pecking my way towards her thighs until I slowly run my tongue over her mound?" she teased, working a little quicker on my cock.

"Oh... Oh... Yesss."

"Then you want to see me lick her clit while pulling her ass to my face, digging my tongue deep into her wet slit until she's cumming hard in my mouth," she cooed as she jerked my dick faster and harder.

"Oh... God... Oh...Yesss. Yesss. Oh... Fuck her with your face, honey!!" I croaked as my cum jetted out of my cock and all over Becky. I had never cum so hard. Between knowing Mom had been watching us and now Becky's lesbian talk, I wanted more of this sexual bliss, and I felt my body quivered out of control as the last of my sperm slipped through Becky's fingers.

"Oh...God Becky, that was so hot," I said as I tried to regain my composure.

Becky slipped her top back on and helped me to my feet. Then, with my dick still exposed, we embraced one another and again passionately kissed before she said, "I think that's enough for tonight, Stud, but it was definitely a thrill."

"Yes, I thought so too," I replied as I tucked my dick away and zipped up.

"I'm looking forward to next weekend already," Becky said as we made our way to the front door.

I walked her to her house and gave her a goodnight kiss. But as I took my time getting home, I relived the night's experience and realized I was definitely getting hooked on what was happening and found myself wanting more.

The next morning at breakfast, I stumbled into the dining room. Both of my parents were already there enjoying their Saturday morning, and I lowered my tired body into a chair before propping my head into my hands.

"Late night, honey?" Mom asked as if she didn't know.

"Umm. Yeah, me and Becky lost track of time; it was around 1 o'clock when I walked her home."

"I hope her parents aren't too upset with you getting her home so late. I know both of you are adults now, but take it from a parent - we still worry."

"Yeah... I can see that, Mom. I'll have to pay more attention to the time."

"You want me to fix you some breakfast?" Mom said.

"No. I'll go make myself something. You enjoy your time with Dad."

"Thanks, son," Dad said as he looked...
