My married girlfriend Yui, who is my sex partner, has become completely addicted to our sex life and barely has any relationship left with her husband anymore (lol). Knowing how pent-up she's become, I decided to try something different and had her cosplay for me. When she changed outfits, she looked incredibly hot, instantly turning me on. Yui is especially skilled at feather-light touches, and as I teased her with them, her body twitched more and more, clearly getting turned on. I kept up the teasing, and she stared back at me with lustful eyes. That reaction made me even hornier, and I started having serious sex with her. Yui sucked my cock like a pro, taking it deep into her throat—the tightness felt insanely good. After getting soaked in her saliva, I decided to return the favor with cunnilingus. Midway through, she suddenly squirted like crazy. I kept licking, and she lifted her hips, cumming hard while gushing repeatedly (lol). There was a huge wet spot on the sheets—so damn erotic. I couldn't hold back anymore, so I entered her from behind in missionary position. Her pussy was incredibly tight. While thrusting, I applied electrostimulation, and she screamed, "Both feel so good! I'm gonna break!" climaxing with the strongest, gushiest squirt of the day. Her hypersensitive body kept leaking squirt with just the slightest electrostimulation (lol). I was so turned on I couldn't stop—I thrust into her again as she rocked her hips in pleasure. I flipped her to doggy and started moving, and she cried, "No, that's too good!" cumming over and over. When I returned to missionary and stared into her eyes while fucking her, I finally reached my limit and blasted a huge load of cum all over her face (lol). That was one hell of an amazing, mind-blowing fuck.
