Apparently, there is an item that checks the health of your sperm.
You are interested in sex, and decide to collect your brother’s semen.
However, the amount of my brother’s sperm that I ejaculated by giving him a hand job or a blow job was so low that it was difficult to conceive.

My brother’s masturbation help is escalating.

You’re not interested in the amount of sperm you’re producing, you’re only interested in your brother’s sex life.

And finally, live sex with your brother.
You’ll be able to get a lot more than just a couple of hundred dollars in your pocket.

How long has your brother been planning to have sex with you?

How long has your sister been fooled by your brother?

●01
When did my brother start planning to have sex with you?
But the sperm count is low, and the brother cries.
You decide to test him again, and he starts masturbating in front of you.
He wants you to help him, so you give him a hand job.
Your brother is so excited that he ejaculates in your mouth during a deep-throating session.
He hurriedly spit it out and examined it, but it was still a small amount of sperm.

●02
He abstains from masturbation for a few days and then tests again.
First, I give her a hand job, and then I make her ejaculate into the measuring cup.

The amount of semen might be too small to be measured, so I pied her some more.

I let her ejaculate into the measuring cup again and scraped it with my finger before inspecting it, but the amount of sperm was still low.

I’m not sure if I can get pregnant even if I cum inside her. That’s what I’m thinking.

●03
I’ve been helping her masturbate a few times, and she’s gotten better at hand jobs and blow jobs.
You’ve learned to enjoy making your brother cum, and you don’t really care about the amount of sperm he produces.
Today, I ejaculated again with a blowjob. But he put it in my mouth and I drank it and can’t examine it.
We both can’t contain our excitement and finally decide to have sex.
I fuck her raw in normal position. I tell him to pull out when he ejaculates, but I know he’s going to cum inside me.
My brother who, as expected, is going to cum inside me. But it’s okay because there’s not much sperm.
So you think, and then you inspect the semen that has been refluxing?
