Shaun pushes things, and starts fucking Anna's mouth

As my swollen head slid back through her open lips, my hips bucked involuntarily, thrusting a good third of my shaft back into her mouth. I groaned under my breath at the stimulation. Even hanging open slackly, Anna's mouth felt so good around my sensitive head, and I just couldn't resist slipping it back between her luscious lips. Slowly, I pushed my cock further into her mouth, withdrawing and thrusting again each time.

She gave no indication she could feel the thick intrusion, so I kept thrusting, building up a steady rhythm. The piss that still coated the inside of her mouth gave my movements a slick momentum. The night's teasing and frustration was building up inside me, and I knew it wouldn't be long before I blew my load.

I placed my hands on either side of her head, just to keep it in line. God, this was so wrong, I thought, but Anna was so fucking hot I doubted I'd ever get another opportunity like this. Wrapping my fingers through her long blonde hair, I pulled her head forward to meet my thrusts. With all the lubrication, and Anna's completely relaxed drunken state, I could feel her throat opening up for me with no resistance. I nearly came right then as, in one motion, my cock slid from her lips, right into the back of her throat. It felt so fantastic I had to do it again.

Consciously, I knew this was dangerous, but the stimulation was just too much. With the lubrication my piss provided, my cock was plunging deep into her mouth, slamming against the wall of her throat. Right before I crested the wave of orgasm, I felt a clenching around the base of my cock, and Anna's head starting writhing in my hands. I looked down, and her eyes were wide open, staring up at me in panic.

In that moment, I came. Hot, slimy ropes of cum shot straight down my housemate's throat, as she looked me right in the eyes.
