Can he resist?

They started to work on me immediately, teasing me by the side of the pool. Milly poured sunscreen into her hand and started to do Katie's back now that she was sitting up. Her hands on her body felt erotic to me. But it was nothing compared to the way she grabbed the brunette's tits from behind her.

Katie didn't move as Molly massaged sunscreen into her heavy pillows of joy. She made a real show of it, squeezing them, twisting them, even bouncing them. What really had me going was when she pinched Katie's nipples and tugged on them.

I was getting flashbacks of what I was allowed to do to her last night.

"Let me get you too before your boobs go red," Katie told her best friend.

The brunette spun around to face the blonde, taking the bottle of sunscreen from her. She poured a generous amount into her own hands before lathering up Milly's body, particularly the twin peaks. The girls sitting so casually as they sun screened up each other's tits seemed natural enough that they had done this before.

My boner was painfully hard. I wanted to touch it badly this morning thinking about last night's adventures and now this was just giving me even more wank content.

The challenge was going to be a lot harder than I thought.

"Have you put sunscreen on Leo?" Katie asked me once she had finished with Milly.

I shook my head, "I'm alright."

"Oh honey, come over here," she repeated, "You'll burn easily in the water, that's where the sun can really get you."

Next to her, Milly shook the bottle of sunscreen around. I watched her tits jiggle as they did and felt my horniness reach another level again.

Although they were mainly doing this to presumable tease me further, I also knew they were right. My skin wasn't great in the sun, when it burnt, it stung. So I pulled myself out of the water, and did my best to hide the gigantic hard-on but it was just no use. They both could see it, it was just inevitable.

"Let me give you a bit of a dry first," Katie said, picking up her towel and starting to use it on me, "It won't work properly unless you're dry."

I felt her dry me down everywhere, something I could have easily done myself. When the brunette got to my crotch area, she purposely gave it a good rub, basically giving my shaft a little bit of hand action.

"Alright Milly, I think he's ready."

The blonde behind me had already begun to rub sunscreen on my back. The liquid was cold which make me jump but once her hands touched me, my body relaxed. Her hands were already warm after running them all over Katie's body. Now they travelled down my back, really massaging the white liquid into my skin. Then I felt her drop to her knees, her long blonde hair tickled the side of my legs as she ran her hands around them. Up and down, to rub it in even though they were still fairly wet.

The whole time she was behind me, I had a half-naked Katie in front of me. A quiet smile on her face as she crossed her arms over those spectacular tits. I started to think the girls were right, I wouldn't last all day out here.

"And spin around," Milly told me, standing back up on her feet.

I did as the blonde said. Now with the view of her big boobs instead as she worked on my chest. It was the first time she had seen me topless as well, "Look, I can already feel a bit of improvement from the gym sessions."

We hadn't exactly gone much yet but the little compliment amid all this teasing didn't go unnoticed from my end. But I was quickly thinking about her tits again that continued to wobble around as her hands moved on me.

"Alright..." she said softly, "You're good to go."

Sunscreened up, I waited a bit before jumping back into the pool. The girls in the meaning had started to sunbake, laying topless by the pool. It's fair to say I never lost my boner, constantly looking at the two sets of big tits that were facing the clear blue sky.

When I ended up back in the water, I attempted to block them out. I can't remember how long but somehow my mind did manage to escape their breasts for long enough to have the girls needing to check in on me.

I saw Milly standing up by the tiled edge, stretching her arms out. Again she knew what she was doing, she knew exactly where I'd be looking at.

"How's the water?"

"Cold when you first hop in but nice after that."

She gestured to Katie to come in as well before jumping from the edge, into the deep end of the pool. Her boobs bounced like crazy on her way in. I was nearby her and copped the big splash from her entry. By the time I was clearing the water from my eyes, Katie had jumped in too.

The two topless babes cooled off in the water, floating around, diving underwater.

What could I say, if big tits were my kryptonite then what could you say about big wet tits?

The way those orbs looked, glistening from the water made my heart stop. I couldn't help myself, I subtlety squeezed my cock underwater, giving it a couple of pumps as I watched them both swim over to the shallow end so that their tits were just above the top of the water level.

"Hands up!" Milly pointed at me.

Oops. She had caught me touching myself. I pulled my hands above the water, pretending to act innocent.

"Oh you naughty, naughty boy," she cooed, "Told you that you couldn't last all day without touching yourself."

At first, I was going to lie but there was no point, they deserved to win this little wager. They had my match all afternoon.

"Fine, okay, you win," I admitted, walking up to them in the shallow end, "But seriously... how can you blame me, look at what I'm dealing with."

I splashed some water on their big jugs that were still visible above the water. Wet breasts, their nipples hardening in front of me.

The girls high-fived each other and laughed.

"So what do we win?" Katie asked me.

I shrugged, "Didn't know there was a winning prize."
