I was cucked by a real man

I am not a very insecure person, at least I wasn't until I started dating my girlfriend. I'm a 5'9 20 year old with no body and my voice still cracks like I'm in puberty still. I've been picked on by everybody about my boyish looks, everyone except Jessica. Jessica and I had been ********* best friends, she was the girl next door I have been pining after for so long. I had worked up the courage over years to ask her out our senior year.

It's wasn't long after graduating high school that we decided to move in together. As two 20 year olds ready to take on the world, it was like a dream come true for me. Every night we would cuddle together and drift off to ***** after a wild round of fucking.

After two months of living together I had the misfortune of running into Mark, the most obnoxious asshole I've never met. He was easily 6 foot tall and had huge muscles with a large pot belly. He looked to be in his late thirties or early fourties' with a bushy beard that had greying hairs. He spoke with a cocksure attitude that just made him sound like an ass. He was everything I wasn't.

The day we met him was supposed to be a regular gym date with Jessica but the entire time this asshat kept coming up to try and talk to us, to her. He would try and position himself between us, interrupt me, and flex his huge muscular arms right in front of us.

It didn't help that after our work out he followed me into the locker room to keep on talking.

"Man Charlie, how did a wimp like you pull a badi butch like that?" He was so loud right next to be that all I wanted to do was tell him to fuck off. "Her tits were banging, are they double Ds?"

As we were changing though I did notice something, as he pulled his gym shorts I witnessed a huge huddle stuffed tightly into a black thong with hair sticking out everywhere. It pissed me off enough that I couldn't even grow a beard like his but this guy could grow pubic hair thicker than me too. That was the true day that my insecurities started.

From then on everyday at the gym this asshat would come up and "workout" with us. It would most consist of him bragging about his PRs or flexing his huge arms. It didn't take long for me to notice his obvious flirting with Jessica either.

After a year of this non-sense, Jessica approached me one day with a suggestion that would haunt me for a long time.
"We should add a third to the bedroom" she said it so calmly over breakfast that I almost ******.
"Why? Am I not good enough for you?" I was on the verge of tears at just the suggestion.
"NO! NO! Not at all! It's just that we're both each other's first, we've never gotten to explore other people and I've kinda always wanted too." She rambled on so quickly that I was having a hard time understanding her.

"Well, who do you have in mind?" I was sick to my stomach just asking but I was aching to know.

"Well, no one in particular, but I'll let you pick, anyways I've got to go to work. Love you!" She scrambled from our kitchen table and out our apartment so fast that I was left in a daze.

As my day went on I thought about who I should choose if I were to agree and while on my lunch break I ran into the last person I wanted to see.

"Hey puny!" Mark said as his heavy hand landed on my shoulder.

"What's up man" I could barely contain by irritation.

"Man for a guy with a hot ass bitch, you sure are grumpy." He said as he sat down beside me in the booth. "What's eating you bro?"

For a second I forgot how much I hated him, but that was all it took for me to spill my guts about our conversation from this morning.

"Aw that sucks bro, but have you considered her offer? Who knows you might be in to it. I mean after all you clearly aren't doing the job for her now, so what's the harm in trying to fix that before she cheats." He said it so matter of fact that I could feel my heart drop and the ***** rush to my face.

"I have been doing the job! I have her cumming every night! You just haven't seen me in action asshole!" I blurted out that last part before thinking it through and I would soon come to regret it as the smile spread across his face.

"Then show me." Those three words of challenge, I felt in that moment if I did back down that I would be saying that I was bad in bed. I had already started typing the message to Jessica before responding.

"I fucking will, my house tonight and after I fuck her brains out she won't even have the energy to look at you." I stormed out the restaurant and marched straight to my car without even thinking.

As night came around, me and Jessica sat in our living room the conversation couldn't stay quiet.

"I can't believe you said yes and found someone in a day!" Jessica was practically vibrating with joy.

"I'm not that insecure that I can't have fun babe." I lied, I was nervous.

My nerves were killing me, I had issued the challenge without a second thought, but it was exciting. I was already hard just thinking about what was about to happen. That's when we heard the knock at the door and in came Mark. He was sweaty and still in his gym clothes.

"Okay let's get fucking started." He said with a perverted laugh.

After a little preparation and teasing, me and mark had stripped down to our underwear with Jessica naked and kneeled between us.

"Bigger man goes first!" Jessica said with a sly smile looking at me.

That was when my stomach dropped. As she pulled down my boxers and marks, our two hard cock came out. It wasn't even a competition.

Marks throbbing erection was easily twice the length and girth of my with much more hair. He was even uncut. Jessica sat shocked for a second before mark spoke.

"Bigger man goes first, sit down Charlie." He chuckled as he slid his boxers to the grounds. "And don't be shy Jessica."

Jessica looked at me and then back at Marks huge sweaty cock before scooting over on her knees to be directly in front of Mark. Her breath was ragged as she slowly put her hands around the base of his cock. First she started in slow methodical strokes, from the base to the tip with both hands.

The burning in my gut was unbearable, but at the same time I had never been so hard before in my life.

She finally stopped and leaned forward, her lips which I had kissed so many times before wrapped around Marks sweaty cock head and she started to lick his foreskin. After a few second of licking she slowly started to move her head down. She slowly went down all the way to the base before she came back up for air with a gag.

"Holy shit" she whispered.

"That's what they all say." Mark chuckled.

Mark then took both of his hands and grabbed Jessica's head. With a gently ***** he started to push her lips around his cock again. Up and down she went, gaging every time at the base, his base, while she never gaged at mine.

I was so hard that I started stroking myself. After a few more minutes of gentle throat fucking, he finally came. As he clenched up and pushed her head down violently, I flinched and came as well.

"Aaauuuggh, who's up for round two!" Mark yelled while pulling Jessica's head off of his cock.
Jesica was still chocking when she answered for me.

" we are!" Her eyes wild with excitement.

"Hold on I need a break I just came," I stammered out while looking for some tissues papers.

"Well while you wait, me and Mark can continue." Jessica said while Mark was groping her ass.

"What! Hold on-" I started but was too slow as Mark and Jessica moved on.

Jessica bend over our couch while Mark walked up behind her. He slowly put on a condom and spread her ass while chucking again.

"It's always the boys who quite first." He sneered as he rammed his fat cock into my girlfriend.

She moaned as he thrusted into her like a jack hammer. Each stroke making her moan again and again. Part of me wanted to stop but the other part couldn't look way as I was hard again without even realizing it. As Marks bear gut slapped against Jessica ass all I could feel was shame, embarrassment, and extreme arousal. I watched as Jessica for the first time in her life started to squirt on our couch to a cock that wasn't mine. After a few minutes. Jessica had Marks stop and she looked over at me. She had a look of disgusted as she talked.

"Babe, I think we're going to need extra condoms, can you go grab some?" Her voice snapped me out of my trance as I looked. Between her and Mark.

"Ss-sure thing babe." As stuttered while pulling my pants up and throwing on a shirt.

I paused outside our apartment door before leaving and pressed my ear against the door as I heard Mark, that asshole, fuck MY girlfriend in a way I never could with a cock I didn't have.

Tears rolled down my face as I drove to the store.
I don't even feel like a real man.
