It had been a month since I moved into a new apartment with my girlfriend Beth and more than two months since she had started having sex with her coworker Kevin.
I could hear them fucking in the bedroom as I waited out in the living room. I was thinking about how much my life had changed. Since Beth first had sex with Kevin she has had sex with two other guys as well, but none as much as Kevin. They had sex at our place 4 or 5 times every week and I suspect while they were at work as well.
On the other hand Beth had sex with me maybe once a week, although she'd have me eat her out after just about every time they had sex. I hated it first, but I was getting used going down on her cum filled pussy. In fact to my utter humiliation I started to get erect just about every time I did it.
"Hey little buddy!" I hear Kevin summoning me from the bedroom. "she's ready for you!"
I walked in and saw Beth naked on her back on our bed. Her legs were spread giving me a perfect view of her freshly fucked pussy. I could see some of Kevin's cum between her wet pussy lips.
I knew the routine. I lowered my mouth to Beth's pussy tasting the now familiar flavor of Kevin's cum.
"Jake, Kevin wants to go another round and you know he likes a clean pussy," Beth said to me, "so make sure you clean out all the cum while you are down there."
I heard a chuckle from Kevin, I still hated that cocky asshole.
I moved my mouth over her vaginal opening and began sucking out Kevin's cum. As I did Beth began to push it into my mouth and I quickly swallowed.
Once I was satisfied Beth's vagina was clean I moved my tongue back to her clit and licked her to an orgasm.
"Thank you Jake, you can leave the room now. I actually would like Kevin to spend the night so why don't you sleep on the couch tonight?" Beth gave me a quick kiss. "Goodnight sweetie!"
The next morning after Kevin fucked my girlfriend again he finally left and I had some alone time with Beth again.
"Sweetie guess what? Kevin got something for us!" Beth showed me a box of condoms.
"He said it weirded him out you cumming in my pussy and he would prefer you to begin wearing condoms when you have sex with me."
"Kevin will be wearing them too?" Maybe I wouldn't need to eat his cum anymore I thought.
"Of course not, that cock is amazing and I want to be able to feel every bit of it. Besides nothing is sexier than feeling is his cum shooting deep in my pussy."
"So only I need to wear them!"
"Yes, but it's not so bad. Kevin is such a sweetheart he even bought the condoms for us. And he got these, they are called snugger fit condoms. Apparently they are made especially for small penises like yours. He is just so considerate isn't he?"
Beth reached down rubbing my erection through my pants. "That's it sweetie, why don't we try one right now?"
I undressed as Beth opened the condom and handed it to me. I easily rolled it onto my dick. Beth tickled the underside of my penis and in a baby voice said, "do you feel snuggly in there little guy? Hehe."
I laid on my back and Beth lowered herself down. It felt strange being in her this way. I could feel the pressure but not the wetness of her vagina on the skin of my penis. Still I was rock hard. I couldn't explain it but lately my stamina was even worse than before. It seemed the more humiliation I felt the quicker I came. This time was no different. A couple rolls of Beth's hips and I filled my condom breaking my own humiliating record of quick finishes.
"Oh my god did you already cum? That was only 10 seconds maybe! I barely felt anything, I assumed you weren't even all the way in yet!" Beth lifted herself from me. "But see no mess! This is great isn't it!"
"I'm not sure Beth, I think I like it more without the condom." I replied.
"Don't be silly Jake, you came so fast so obviously you loved it! Besides at least Kevin is letting you still have sex with me right?"
"Why would I need HIS permission? I'm your boyfriend!"
"Maybe but... I think he kind of laid claim to my pussy with his huge cock. It sort of usurped your tiny one." Beth continued, "Besides he's this strong alpha man type. Even you've got to admit he is more masculine and tougher than you. It is safe to say he owns this pussy!"
"Speaking of," Beth paused. "I need you to take some naked pictures of me for Kevin. He wants to show a buddy of his from the gym. He wants to try a threesome with me!"
I took a bunch of pictures showing every detail of my girlfriends naked body to this guy I never met. "There is just one more special picture Kevin asked for, come over here."
I hesitantly walked next to Beth, I was still naked from the sex we had. Now that I had come my penis had retracted to the point just the small head was poking out. Beth put an arm around my leg and had her face against my hip and snapped a selfie!
"What are you doing?" I asked.
"Kevin had this really funny idea. We are going to send this picture to his friend after all the others with the tagline 'why poor Beth desperately needs our help' isn't that hilarious!" Beth nearly fell on the floor laughing.
