No shirt and no shorts

They were in there for far longer than they needed to be. I could hear muffled giggling and talking through the door, and maybe even a slapping sound at one point? Had Callum tried something leaving Sarah to slap him in retaliation?

I wanted desperately to barge in and see what was happening, but I already knew what would happen. Sarah would say I didn't trust her, or that I was being overprotective. She was clearly in a mood tonight and I wasn't about to let any suspicious ruin our perfect lives together.

Eventually they came out of the room, and I couldn't believe what I was seeing. Sarah wasn't just shirtless anymore, she had also taken off her shorts! Now she was only wearing her bra and a matching lacy thong that made her ass look even bigger than it already was.

"See, I told you he'd love them!" Sarah said to Callum, clearly catching me staring at her.

"Guess you're right then, you win the bet." Callum said, draping his arm around her again.

"What's going on!" I really could believe how they were acting, even with Sarah having a bit to drink.

"Callum didn't think you'd appreciate these." She gestured down to her exposed lower half. "But I knew you would, so we had a little bet about it."

"That's not... why are you just in your underwear now!" Was I crazy, how didn't she get that was what I was talking about?

"Oh right, well I figured I might as well clean both at the same time. I want to make sure they're both in perfect condition for you." She skipped over and kissed my cheek, her warm body pressing into mine. It was a moment I'd like to appreciate alone, as is my mind was focused on Callum who was staring right at Sarah's ass.

"Thanks Sarah." I said, trying to sound sincere. "You must be cold though, let's get you into something thick and warm."

"I'm actually quite hot!" She exclaimed, bounding off me and falling backwards onto the couch. She fell with so much **** her boobs very nearly spilled out of her bra.

"I really don't think I'm comfortable with you dressing like that when we have a guest."

"Oh lighten up boy." Callum slapped me on the back hard, knocking the wind out of me. "This is a party, we're just having fun!"

"Yeah it's a party!" Sarah stood up on the couch and began dancing to non-existent music, swaying her hips back and forth. "And it's like Callum said, I'm not showing any more than I would with a bikini!"

So this had been his idea, why wasn't I surprised. They were right in a way, even if I'd never seen Sarah wear a two piece bikini before.Still, what made my blood boil the most was the idea that Callum got to see her wearing this sexy underwear before I did!

"Maybe we shouldn't be jumping up on the couch though. I don't want you to trip up." The only thing that could make this nightmare worse would be seeing my beloved get hurt.

"Hmm fine." Sarah said, a mischievous smile rising on her face. "Catch me!"

She leaped off the couch towards me as I braced myself to catch her, suddenly finding myself being shoved to the ground.

Callum had pushed me and taken Sarah from himself. He gripped her bare ass tightly and held her just high enough to have her boobs press into his face. He let go of her before I could lay into him, but that smirk on his face told me he knew what he was doing.

"Sorry bro, your weak little arms wouldn't have been able to catch her. Not when her two fat stacks weigh so much."

"Ok that's enough! You've been trying to feel her up all night!" I stood back up, putting myself between this bully and the love of my life.

"Hey that's a serious accusation! I have a girlfriend you know and I don't appreciate you accusing me of cheating on her!"

"Come on Liam, please don't ruin the mood. We're just having fun." Sarah pleaded with me.

I didn't think any of this was fun, but I had just caught out this lying bastard!

"If you have a girlfriend, why aren't you staying with her then?" I said smugly, breaking apart his whole reason for staying here.

"We're long distance bro, she doesn't live anywhere near here."

"Come on Liam, after the last two years we've had you should be more sympathetic!"

Sarah moved in between the two of us, holding both our hands.

"Can we promise not to fight guys. I know we didn't get along years ago, but that was high school. I'd really rather forget it ever happened and just move on with our lives."

Maybe I was letting our past history colour my impressions of Callum now. Was I just seeing rude and inappropriate behaviour where there was none? My instinct told me not to trust him, but maybe he had changed and I just couldn't see it.

"Ok, no more fighting." I said, trying to let go of the tension within me.

"I'm sorry if I've been giving you the wrong impression, I really do want to be friends now." Callum said. He still had that annoying smirk, but I guess that was just how he looked all the time.

"I'm so happy guys, group hug!" Sarah pulled us in for a hug, wrapping our arms around each other. I could swear Callum's arm was resting dangerously close to Sarah's ass, but I couldn't tell without obviously looking over.

I'd have to trust in Sarah's **** instincts, trust that Callum really didn't have eyes for my future fiancee.

"Well, now that that's settled, I should also settle my bet!" Callum walked off from the group hug, leaving me alone with Sarah.

"Right, ummm. What was this bet exactly?"
