... licking my cum, while moaning and biting my spewing cock. She quickly got up, and looked at my face, covered in her juices, then swiveled around, and straddled herself over my cum covered cock, sliding down on my whole eight inches. She lifted herself up and down, sliding her cunt up and down my slippery shaft, moaning and screaming with pleasure. I cried "Get off me, you're cheating on your sister!" "I don't care, I want your big hard cock in my cunt, it feels so good and I haven't had sex with my husband since I came here 6 months ago!" I could feel her cervix bumping against the knob on my cock, and this made her moan even more as she came again, as she rode up and down my cock, until she finally fell down, laying on my chest with her soft, warm body. "Can I have my picture now please?" "You can have a copy, I'm going to keep the original, just in case I need something from you later". My heart sank, but at least I had her word that she wouldn't tell my wife what we had done, as my wife would have kicked us both out! "Can you untie me now please?"

"So what do you want then?" I quizzed. "I want to watch you wank off for me, or I'll show Jessica that picture of you at the computer!" Her eyes suddenly spotted a pink object on Jessica's bedside table, and lit up is surprise "What's that for?" she said, pointing at the pink dick object on the bedside table. I tried to make excuses and said "It's a decoration, you can keep lollies in it!" She laughed, and said "OK, it's a lolly, I want to see you suck it and then stick it in your ass and cum for me!" I scoffed at the idea, "No way, what do you think I am, gay or something?" She glared at me. "Maybe we can ask Jessica when I show her this picture" and produced the camera from her robe's pocket. She walked across to the bed, and snapped a picture of the toy, and then sneaked to the bathroom door, opening it ever so slightly, and peeping inside. Jessica was washing her hair, and Courtney took a few quick pics, then quietly closed the door. "She's just started washing her hair, that will take another 20 minutes" she chuckled.
