One of the best ways, I used to fold the pillow over my cock and go to town. Have not done it in a long time but I may just have to now.
One of my friends still does this. She prefers the edge of a couch...something like that. With jeans on...well, that's a longish story that I can share in a PM if anyone wants. At any right, she's a humper.
I'm happy to hear all about it. I watched a friend use the edge of a clothes washer. Never IRL but in videos I've seen women use the edge of hard fixtures, like tables and desks. Egad! I mean, I'm sure they wouldn't do it if it didn't feel good but it just seems so... I dunno... hard? LOL
I'm not fucking my pillow the way you others are, male or female, as a masturbation tool. I strip off all my clothes in the bedroom, and that nudity makes me feel so gay, and I imagine there's a naked guy in my bed, and I dive into my bed and grab my pillow like it's his body, and begin passionately kissing "him", my tongue going crazy against the pillow imagining it's the inside of his mouth and his tongue, rubbing our cocks together, tightly embracing each other's as we roll around with passion, me holding the pillow tightly as I roll around on the bed, our beautiful male bodies tightly together in a loving embrace. I finally place my pillow down on the bed, my lover on his back, and dive down and begin rimming the bottom of the pillow, making his asshole very wet for my cock, and I finally insert my cock into the bottom of my pillow, imagining I'm penetrating his beautiful hole, and then I begin to fuck him good and hard, making love to this amazing man, rubbing my cock into the bottom of the pillow like crazy, humping it, fucking him. God, it's almost gay heaven. Of course real heaven is when I'm with a real man doing that, which doesn't happen anywhere near enough. Thank God for pillows.
