Do you also like it on your back with your legs raised/pulled back? This is my other favourite way to be fucked. For me, it's totally submissive. While on-all-fours is submitting your ass, you have some freedom to move. On your back, you're submitting totally. Nothing says "I'm just a hole, I'll lie here while you use me" like opening up on your back. I've found it also gives really great access to my ass. I had a great fuck buddy years ago with a smaller cock, and this gave him easy access and it felt deeper for both of us. For me there's the added bonus of prostate stimulation, especially when he lifts up my ass to get more depth. I've sometimes creamed hands-free while being fucked on my ass.
On all fours I like to only feel, not see him, but there's also a special thing about looking into his eyes as he's fucking. One "straight" married guy fucked me on my back on the edge of the marital bed, he was standing, and as he built up to cum, he lifted my ass and his face contorted and he got this wild, crazy look in his eyes like the Devil Incarnate as he pushed and released in me. That was so hot to see. Tell me about your other favourite ways. Do you like it on your back?
