Sperm whale in the pool

"OK OK, PLEASE! Just promise I'll get my trunks back, ok?"

"I promise." she said crossing her fingers as she sat on your swimsuit.

"Better hurry. The other guests might arrive soon....hehe."

I look down and my erection was floating in the water. Despite the chilly water, I was hard as a rock. I wrapped my hand around it and brought my hand up and down, very slowly.

"Yessss....that's a good boy. Now show me what that big long thing can do."

At first, I tried not to look at Jen. But then she kept taunting me about my lewd act in the pool, saying that I was stroking my "eel" right in front of her and how there was a massive sperm whale about to blow.

I went faster if only to make this end sooner, but that's not the vibe Jen was getting as I picked up the pace. "Boy, John, you're really enjoying this aren't you?"

"N-no I'm not..." I said between breaths. Try as I might not to enjoy this, it was starting to feel really good.

"So, you don't enjoy the fact that a fully clothed sexy woman is staring right at you as you masturbate right in front of her? I know what you look like, completely nude and nothing will ever change that."

"No...I'm not into that."

"Look me in the eyes and say that again."

I did so, stopping my stroking for a moment. I stared at that face that was drinking in every inch of my body. "Hey....I didn't say stop. Keep going and say that again."

I started to stroke once more. "I....don't like this."

"Then what are you whacking off to?"

"Excuse me?"

"What are you stroking yourself to? I can tell that thing is about to blow, so out with it. What are you thinking about that's going to make that big thing cum?"

I had no clue how to answer. That's when she threw out a few potential responses. "Could it be that I have my bathing suit on and you're completely nude and loving that fact your showing off to me?"

"No!"

"Maybe its the fact that at any moment, I could call all the girls over here and we can watch you rub that sausage and you couldn't stop us? You like getting dominated by sexy girls, don't you?"

I was breathing a bit heavy as I felt the pressure building up. "N-no!"

"So you aren't imagining all of us, in the pool with you right now, staring right at you as you jack yourself off. Looking at you all sexily as we moan out your name. "Oh John! OH John! Cum for us, John, cum for us!""

If I wasn't thinking of that, I was certainly thinking of it now. I felt my balls tighten as I saw them all looking at me. Eventually, I let loose, grunting as I try to hold back my moans. Jen sees my cum shoot out in the water. Globs of white float to the surface as I feel my dick throb with each spurt.

As I come down from my orgasm, I hear Jen say, "Thar he blows. What a beautiful sperm whale you got there. Hehe~!"

"Ok, a deals a deal, give me back my trunks!"
