An Agreement

Gangbang

I have two sisters, and they’re both bitches. I’m eighteen, and my sisters are one and two years older than me. Somehow they became accustomed to teasing me about jacking off. Marin, the younger of the two, walked in on me jerking it. She barged into my room without knocking, and I was naked on my bed really getting into it. She began laughing and hurried out of the room. I was so embarrassed, and it was pretty obvious by the double laughter that ensued that she had told my other sister, Rena.

From then on, they always smiled wickedly at me, and joked with me whenever it was even remotely appropriate. They kept it under control around our parents, but if the three of us were home alone, I just wanted to lock myself in my room. But then they would just tease me even more about being alone with myself. I always stood up to them, but two against one always wore me down. So when I had enough of letting them tease me, I began playing along with them.

If they started teasing me about jacking off, I would agree with them that I had indeed been jacking off, every single time they joked at me. I would describe in detail my masturbation practices. At first, they were always turned off, and I thought they had finally grown tired of teasing me. Especially when I would talk about how much I ejaculated. They would always wrinkle their noses and leave me alone.

However, one day Rena made a quip about me being selfish or something, and that “apparently that’s what self-love does to you”. Another of her endless masturbation jokes. I was quick to respond about how loving yourself was better than being with a bitch, or something lame like that. Rena turned her nose up at me and walked away.

Marin, however, kind of laughed.

“Geez, Rena is a bitch, isn’t she?”

“What? You’re just as bad.”

Marin smiled. “I know, but we’re just having fun with you.”

I felt like poking some fun at her. “Maybe you wish you got it as good from your hand as I do from mine.”

Marin laughed. “What makes you think I don’t?”

I just stared at her. “Don’t even tell me you frig yourself, and then tease me about doing it.”

Marin glanced around, in case our parents were nearby. Everyone was going to bed, and our parents were in the next room.

“Let’s talk in your room,” Marin said, pulling me into my room.

She closed the door, and sat on my bed. It was odd for her to be so warm towards me.

“There’s nothing wrong with masturbating,” Marin blurted. “We just like to tease you about it because it kind of turns us on.”

The thought of my sisters getting off with me in mind was kind of arousing. I had never really thought about istanbul escort my sisters having sexual thoughts or masturbating. It was always one of those things that you knew happened, but you never thought about. Now it was all I could think about.

“Rena frigs herself too?” I asked.

Marin nodded.

“Wait, how do you know for sure?” I asked.

Marin smiled. “Because I’ve seen her. We watch each other.”

I suddenly felt my dick pressing against my pants. I had to sit down on the bed and cover my lap to hide it. Marin enjoyed teasing me like this.

“Really?” I asked, very interested. “Why?”

Marin shrugged. “It gets us going. We’re not lesbo or anything, we just get off having someone watch us.”

“If you’re not a lesbo, then why do you have your sister watch you instead of your brother?”

Marin cocked her head. “Because sisters share everything. Besides, we might be tempted to have sex.”

Somehow that almost made me shoot off in my pants. Marin caught a quick glimpse of my erection straining under my pants, and smiled.

“We should just agree that we won’t have sex, just watch each other,” I said. “Besides, we can’t do it without protection anyway.”

Marin hesitated, and then shrugged. “Okay. So we don’t fuck, just masturbate.”

Hearing my sister swear, especially that wonderful word, really got me off. I waited until she started taking off her clothes. I took my shirt off, and she did too. She didn’t wear a bra under her nightshirt. After she pulled the shirt over her head, she nervously tossed it aside and let me stare at her tits. I tried not to stare, but seeing her tits was really nothing compared to watching her finger her pussy.

I took my short off next, and sat in my boxers. My erection was so obvious I might as well be naked. So while she took her panties off, I took my boxers off.

There we sat, naked and staring at each others’ bodies. We made eye contact finally and Marin sheepishly smiled.

“It’s pretty big,” she said, her eyes falling back down to my dick. “Have you measured it?”

I swallowed, never before having exposed myself to a girl. “Seven inches.”

She raised an eyebrow. “Really? I never thought seven inches would look so good.”

I blushed, and my cock twitched, to Marin’s surprise. She giggled. I leaned back, letting her get a good look at my balls too.

“Well, what do you want to do now?” she asked.

“This is the part where we masturbate, right?” I said.

She nodded. “Okay. We don’t have to be embarrassed, since we’re both after the same thing. One of the things Rena and I were always nervous about was cumming in front yenibosna escort of each other. But after we did it, everything was cool.”

The thought of my sisters masturbating in front of each other really got me going. I instinctively grabbed my dick and tugged at it. Marin took that as a sign to start, and her fingers found her pussy. I watched her trace her slit all around, and she played with her clit a bit. When her hand began fondling her tit, I lost myself in my own self-love.

I jerked it good, and Marin kept up with my pace. She began frantically rubbing her pussy, spreading her lips for me to see. I couldn’t stop wanking myself, and I knew I was going to cum soon. From Marin’s breathing and bucking, she was too.

“Do you want to cum at the same time?” I asked, gritting my teeth.

Her eyes rolled back into her head. “You’d better hurry then!…Eeeeeeaaaaaaaaaahhhhhhhh!”

Marin came so loud I was sure someone would hear us. But in a moment I went over the edge and let loose into the air. I shot up pretty high, and it fell back down on me and some of it shot onto Marin’s arm, which was busy rubbing her pussy. I came a lot, and our orgasms both settled until we were left panting.

I watched Marin rub my semen on her arm. She smiled, feeling the texture.

“You came a lot,” she said. “And it’s so thick!”

I just stared at her. Our eyes were locked for a few moments, until she finally got up and stretched. I got a fabulous look at her naked body. She smiled at me.

“That was fun,” she said. “You were right, it was better having you watch me. It really turned me on having your dick to look at.”

“Are you going to tell Rena?” I asked, worried a bit.

Marin shook her head. “I don’t want her to get jealous. Besides, I can tell you all of the things we do together.”

The thought made my dick twitch. I cleaned myself off, while Marin put her clothes back on.

“Do you want to keep doing this?” I asked her.

She glanced at my naked body, contemplating it for a moment. Then she smiled at me.

“Yeah.”

I grew nervous all of a sudden. “You know, I’m a virgin.”

Marin paused. “I am too.”

“Really?”

Marin sighed. “Somehow that makes me feel better, knowing we’re both the same. Rena isn’t, she’s had sex quite a few times.

“Rena’s a slut?” I asked. “That’s too perfect.”

“The temptation to fuck is going to be stronger for us.”

“What do you mean?”

“Neither of us has had sex, so we both want to know what it’s like. And if we’re both really horny, we might just go for it in the heat of the moment.”

“Then sefaköy escort we should plan for that,” I said.

“How?” Marin asked.

“We should have sex.”

Marin looked at me oddly. “We can’t.”

“We’re just going to frustrate ourselves by masturbating. If we just have sex once, then we won’t be tempted later on.”

Marin thought for a moment. “You’re going to have to pull out, since we don’t have any protection.”

“So you want to?” I asked.

Marin nodded excitedly. “Yeah, it’ll be great.”

“When? Tomorrow?”

Marin shook her head. “Tonight. But later.”

I was surprised she wanted to do it so soon. But I wasn’t going to argue.

“Come to my room after midnight. We’ll have to be quiet.”

I nodded, and she smiled before leaving.

I had to wait for about an hour for midnight to come. I laid on my bed with a full erection thinking about Marin’s sweet body. I couldn’t believe I had just masturbated with her, and now I was going to fuck her! When midnight finally came, I quietly went from my room to Marin’s.

I was careful to close the door quietly behind me. Marin was naked on her bed, and I approached her without saying anything. She didn’t say anything either, our eyes were fixed on each other. I laid on top of her, my dick pressing against her stomach. I grinded my groin into her, and we both moaned. I kissed her on the lips, and we wrestled each other’s tongues for a while until we were ready to fuck.

I moved myself into position and spread her pussy lips with my cock. I slowly entered her, and savored the feeling of filling her up. I broke through her hymen with only a gasp from her. I began fondling her tits eagerly, while she ran her fingers up and down my back.

“I’m cumming,” she whispered into my ear.

She threw her head back and silently cried out, holding me tightly to her body. She kissed me as she came down from her orgasm, and I could only give her a few more thrusts before my own orgasm came. I withdrew from her and aimed my dick at her chest. I grunted as I released thick jets of semen onto her body. I covered her stomach, and managed to tag her breasts too. She was delighted to receive my cum all over her.

We kissed for a while, and eventually we nodded off. I awoke early the next morning, and I hurried back to my room. The next day, Marin and I kept our sibling distance, until she pulled me aside and told me Rena wanted to masturbate with her. They both went into Rena’s room and I entertained thoughts of them pleasuring themselves with each other. Somehow I had to have Rena too. I wasn’t even sure Marin and I would have sex again since we had agreed to do it only once. But if we were all in on it, then things would be more open, and Rena wasn’t a virgin anyways so she would have protection.

Marin and Rena emerged from the room after a while, and Marin flashed me a smile. I decided to enlist her help in taking Rena.
