Weird Couple

Perhaps my wife and I are a weird couple. We don't have sex all that often, although I guess with two grown children, we've done it often enough. We like other things. She likes inner labia stretching. She likes me to pull and pull. Oh, I don't mean hard enough to hurt her. She just likes the feeling of being tugged on. I'll do it for an hour sometimes. Meanwhile, I'm hard the whole time. Somehow, and I can't explain why, it's a real thrill for me to do that for her, almost every time. Sometimes she'll orgasm just from that, but generally not. Usually, I finish her off with a good licking while I probe her butt with one finger. She likes just one finger. Years ago, we experimented with more fingers, and got her up to four, and four in her vagina too, but these days, she just likes it simple. There are two versions of labia pulling. One is dry. I can get a good grip and pull hard. That doesn't usually last very long. She'll get all wet. Her labia become slippery, and so my fingers keep slipping off. I don't get a good grip, and keep trying. This is what can send her into orgasm on the somewhat rare occasions when she does orgasm from this. Every now and then, I'll dry her labia as best I can, and pull and kind of shake really hard. She loves that, but doesn't orgasm from it. I swear, her labia are somewhat longer than they used to be, but she claims they've always been the same length. That's her. Perhaps I'm even weirder. It started with gentle testicle massage. A few times, I've orgasmed just from that. She'd start by very lightly massaging my scrotum. Then, she'd get a good grip on each testicle, one between each thumb and first two fingers. She'd squeeze until the testicles would slip out of her grasp, popping into another position in my scrotum, like wet bars of soap. It's fun. I can never tell which testicle will slip out first. She does it on purpose. It's kind of a guessing game. Which one will pop out? Yes, it kind of hurts, but I love it. Lately, she's been squeezing harder. It hurts more, but I'm enjoying it more. I don't understand it, but who am I to ask questions?< She says the more I yell and squirm, the wetter, and hornier she gets. I've read several times that the gonads are like chicken gizzards, with very rubbery thick outer layers, and pretty much impossible to damage just with finger manipulation. Sharing that info with her gave her an idea. We have an old set of encyclopedias. She decided she wanted me to lay my testicles on the edge of a table, and she'd pile more and more books on top until I screamed, "Stop!" The first time we tried it was just last Thursday. She put a book on, and my balls popped up into my scrotum before much pressure was applied even by that first book. OK, back to the drawing board. She tied a bandana fairly tightly around my scrotum so my balls couldn't slip away. Then she put the book back on. I felt the pressure, but it wasn't in the slightest painful. My penis was rock hard, and she was having fun too, as I could see a drip of liquid escape from her vagina, and her nipples were as erect as my penis in their own way. She added another book. Still, pressure only, no pain. With the third book, we had to start over. The angle wasn't right, and the books were sliding off each other. Finding a small paperback book, she put it under the far edge of the first book so that the books would be level, but almost the full pressure would be squeezing down on my balls. My that felt nice! She slowly added books, in alphabetical order, of course. By the time we got to F, my balls were starting to hurt with that flaming kind of pain that anyone who has played with ball squeezing is familiar with. She added G, and the pain wasn't much worse. Staying like that for a couple of minutes, the pain entirely subsided. Now all I felt was pressure, and it was extremely nice! My mind was thinking about what it would be like when she got several more books on the pile, and then it happened. Wham! Cum started squirting spasmically out of my penis of its own accord. I was having a wonderful orgasm and there was nothing I could do about it. She wanted me to hold still after my cum, and add more books, but you know how it is. My attitude shifted, and I was done. I do believe we're going for at least ten volumes later today when she gets home from work.
