Give in to desire

Actually having a girl touch my cock would be nice, but getting so see Candi's massive tits and getting to finger her pussy? That was worth looking like a bitch in front of the other two girls.

"Hold the fuck up. You can't expect me to go along with this." Sam said in her whiny tone.

"It's just hand stuff babe. It's not cheating or anything. We've been over this." Candi held the glass precariously over me. My jaw starting to hurt from being open too long.

"What?!" Sam said. Exacerbated. "That's so clearly not the issue here!"

"Riiight okay I get it." Candi said mockingly. "My precious girl is a little uncomfortable with her brother fingering her."

Shivers went down my spine. Fuck I hadn't even considered that as an option.

"I think you should be a bit more open to what the universe presents to you." Tands said like she was giving ancient wisdom. "You might find yourself less tightly wound."

"Shut the fuck up Tandi."

"My case in point." Tands, or Tandi I guess, said. Smiling blankly at me.

"It's fine, he doesn't have to do you." Candi said. "Just us two is fine, right?"

"Do you..." Sam stopped herself. Hesitation and insecurity painted all over her face. "Yeah. That's fine."

It didn't feel like it was.

"Then hold on to your dick boy."Candi jolted me a little closer to her. My chest pressing into her soft overflowing cleavage. "Let's see if you're a man or not."

She was really playing up that aspect. Which was especially cruel when she'd told me to lose on purpose. Whatever. I'd play it tough and cool, only coughing slightly at the end.

Candi tipped the glass over and I learned the neat fact that fire can exist as a liquid. They told me it would burn, but only now was I appreciating how that could feel. Like an acid was going down my throat, dissolving my flesh.

From the first drop of it I was instinctively coughing it up. Tandi giggling innocently with glee while my sister brooded on the couch. Looking mad at me for not being able to handle it.

"Wow, loser and a quickshot." Candi smiled. Her tongue running over her dark black lipstick. "Well... maybe this will toughen you up."

She tipped the glass over. Igniting my whole mouth in a hellish fire. Like an animal I bucked and struggled against the pain. Coughing up and spitting up most of the liquid she dumped into my mouth.

Spitting it all over the thing in front of me. Which happened to be her tits.

"Look what you did you little fuckstain!"

"Down puppy." Candi held out her hand. Warding off my sister.

She stopped charging me but remained standing. Glaring at me as I gasped for air and coughed out the remaining drops.

"Down." She said again. More commanding and paired with a hand gesture pointing downwards.

She complied. Getting on her knees but not looking happy about it.

"Come." Again she gestured. Like she was actually commanding a dog.

On all fours my sister walked across the filthy carpet. Her face bright red and blushing as she waited in front of her girlfriend.

"Good girl." Candi pat her head and I could see Sam's eyes roll up. If she actually had a tail it would be wagging like crazy right now.

"I love it when you do that to her." Tandi wrapped her long arms around me. Resting her head on my shoulder. "Doesn't she just look happier like that?"

She snarled at us and then went back to enjoying the head rubs. It was a little fucked up, but Tandi was right. My sister was less of a bitch when she was acting like a bitch.

"Oh that must be Liv." Tandi said, rushing over to grab her buzzing phone. "I'll go help her up. And I'll collect my prize later if that's okay!"

She giggled at me as she bounced out the door. I wasn't sure if I should be aroused or scared to give her that prize later. There was something sinister behind that vapid aloofness.

"Oh she's coming?" Candi stopped petting my sister and picked up her glass. Downing the whole thing in one long go. "Guess I better go get cleaned up. You two play nice now. And if you wanted to give your sister her prize in secret...now's the time."

As she left to the bathroom my sister got back onto her feet. Sitting back on the couch like nothing had happened.

"You're such an embarrassment to have around."

"What?"

"Just take the drink and say thank you next time, please." She kicked up her feet on the couch. Scrolling on her phone while talking to me. "Would it kill you to not be a lame loser for like five minutes?"

In silence I walked over to the bench with my original drink on it. Cautiously taking a sip. It was good actually. Kinda sweet. Cool and refreshing, but also made me feel warm?

"Are we just not going to talk about that?"

Sam looked up from her phone at me with a tight intense glare.

"I'd rather not."

"It's weirder if we don't."

She slammed her phone down in frustration. Eyes turning off me and onto the ground.

"I have a fetish okay? Is that what you want to hear? That your sister is a big lesbian freak who likes acting like a puppy? Do you feel better now?!" She looked about ready to bite my head off. More angry and defensive than I'd ever seen her.

"I don't think you're a freak." I drank more. Letting it soothe my throat.

She seemed a little taken aback. Unsure if I was being genuinely cool with this. This was probably a chance for us to get closer. For us to move a step towards fighting less. But a part of me couldn't help but nettle her.

"You know... I have always wanted a dog."

"Fuck off."

"I can take you for a walk to the park. Teach you to fetch my slippers."

"If you don't-" She stopped her threat mid sentence when her phone buzzed. I would have kept messing with her, but in a strange coincidence my phone went off as well.

I looked at it and there was a message from an unknown number. No words. Just an attachment. A picture.

Candi. In the bathroom. Tipplers and tongue out. A hand grabbing her right tit to bring it closer to her tongue.

Fuck it was so worth taking that shot for this. They were so perfect. So big and soft and full without a hint of sag. Her large plump nipples accented with silver piercings that just did things to me.

I wanted to suck on them so bad. To rub my face over them and just take in the scent. They still glistened in the light from the drink I'd spat up. But that wouldn't stop me from diving right into them.

A noise from Sam grabbed my attention. A faint moan slipping out of her lips. She looked at her phone, eyes filled with the same kind of longing I was feeling right now... could she...

A reflection on the glass door leading to the balcony confirmed it. I couldn't make it out completely, but the shapes and the colours were close enough.

Candi had sent both of us that picture.

I felt a touch bad at that. A reminder that this was my sister's girlfriend's tits I was drooling over. But it sounded like they might have an open relationship? At least partially. Maybe....

A message popped up below the picture. Bookended by black heart emojis.

"Hope you enjoy your prize loser ;) I'll be taking mine later tonight.”
