The Aliens Discover My Balls

My girlfriend Grace and I have been on this alien ship for what seems like days. It's hard to tell how long it's been, because they put us to sleep between experiments, but I think it's been at least a week. They probed and prodded us, stuck tentacles in just about every orifice, and they've made us orgasm over and over. It's pretty insane.

I was nervous because I just woke up, and that means more experiments. I looked toward the back wall, and I could just make out two dark shapes moving towards us. Two tentacles appeared, each with small openings, similar to a mouth without teeth. They moved to my balls, each tentacle sucked in one. It felt good as they gently kneaded my balls.

"What are you doing to me?" I asked nervously.

"We're interested in these, they hold your seed, and yet they're so weak."

The other alien moved towards Grace, "And the female doesn't seem to have an equivalent weakness." A pair of tentacles appeared between Grace's legs, and they moved up and down them as though searching for her testicles. She squirmed as it toyed with her.

"We're going to do some testing now. This might be a little painful. We'll monitor your vitals, you'll be fine."

The other alien spoke to the first, "What are you going to start with?"

"I think pressure."

"Yes, that should be interesting."

The tentacles on my balls began squeezing harder, then harder and harder. Fuck, it was starting to hurt. Just a tiny bit harder each second.

"Fuck," I groaned as the pain ramped up on me quickly. My balls felt like they were getting flattened inside the tentacles. It became hard to breathe. "Fuck! My balls!"

"OH FUCK!"

"STOP IT!" I felt sweat breaking out on my forehead.

"PLEASE STOP!" Tears ran down my cheeks.

"YOU'RE GOING TO POP THEM!" I cried out.

Suddenly, the pressure eased up, "Pop them? They pop?"

I panted, trying to catch my breath, "Yes, they can be ruptured. It will render me infertile."

"Your species is really a mess."

"Perhaps you should try blunt force," the second alien said.

"Yes, good idea."

I watched warily as the two tentacles backed away from my red and aching balls. Another tentacle appeared, this one formed into a flat surface, almost like a spatula. It suddenly whacked my balls.

"FUCK!" I cried out in surprise.

"Oh, that hurt him, do it again."

"MOTHER FUCKER!" I cried out as the tentacle slapped at my balls again. It was a much sharper pain than the squeezing. It fucking stung.

"Do it some more, let's see if they swell up."

"FUCK!" I groaned as the tentacle began a series of rapid slaps at my poor balls. I squirmed in the restraints, but I couldn't get away. My balls seemed to be getting more sensitive with each slap, until I could barely stand another one.

"PLEASE! IT HURTS SO MUCH!"

"He's so vulnerable."

"PLEASE STOP!"

"Look at him, crying and shaking, just unbelievable."

I couldn't speak, the pain was too much. I struggled to breathe as my balls felt like they were being destroyed.

"FUCK! Stop it, you people are animals," Grace cried out. "Stop hurting him!"

"Oh, alright. You two are no fun."

The tentacle stopped smacking my balls. They still ached and throbbed, but it wasn't getting worse any longer. I lay shaking in my restraints.

"We went too far, you should give him an orgasm," the alien closest to Grace said.

"Yes, you're right."

I could barely even watch as a tentacle worked its way between my legs, slowly approaching my soft cock. It gently toyed with the head of my cock, it felt like a pair of lips on the head. It sucked and squeezed the head of my cock until I became hard again, then it sucked me in. I pulsated and sucked as it slid up and down the length of my cock. After the pain I had just endured, I was surprised how quickly I forgot all that. All I knew was pleasure, incredible pleasure.

The tentacle that had been sucking on my balls earlier came back up between my legs. It found my balls and wrapped around them, then it sucked them in. That was what pushed me over the edge, it felt so good as my cock was getting sucked. I couldn't hold back, I had to release.

"FUCK!" I moaned. "OH FUCK YES!" My entire body seemed to tense and then release with each spurt of cum that I shot into the tentacle. It sucked and sucked as my cock throbbed. It sucked me until my balls were completely drained, then it slipped off my cock and slithered away.

"Feel better?" the alien asked.

"Much, thank you."

I felt sleep coming back over me. I looked over to see Grace closing her eyes. Here we go again...
