"Hey, you can't do it with me, but you masturbate?"

I saw you secretly doing it. Your nipples were twitching and squeezing, weren't they?
If you like stopping just before climax that much...I'll make sure you tease me a lot.
At first I was a little surprised, but...hehe, I'll be persistent, gentle, and whisper to you as I manage your penis.
I'll tie it up tightly so you can't get out even a drop, and make you squirm.
You want to cum? No way. I'll end it with a punishment.
I won't let you cum, even if you cry or beg.
But don't worry...I'll be by your side the whole time, and I'll tease you a lot.

This is our 'real married life', right?
