We set the rules from the start before we even moved in together. What it amounted to was I am not a wimp and would never be used as one. We'd have se... with each other but also with others.She would be treated like a lady, and could refuse to have sex with anyone she wasn't comfortable with. I just needed to know ahead of time who she'd be with. No one was just going to use her. She was my girl and I would protect her.When we boarded the cruise ship, I knew we kind of stood out. A fashion model. I continue to allow him use of my mouth while I grab my nipples. I pull them outward and upward, shaking them hard, making each of my tits sway. I imagine him looking at them, but I can't look up. I drop them, and they fall back against me. Again I blush with embarassment, and again I feel a rush of wetness in my crotch."Don't stop" he demands, and I can tell he must be getting closer. I reach under my breasts, and flop them up and down. I cup them in my hands, and shake them. It feels so. I could feel her pussy slowing and then stop spasming. She groaned and pushed back against me.“I'm sorry, Diane,” I gasped.“Mmmmm, sorry? Sorry for what?” she dreamily said without even looking back at me. “I tried, but I couldn't pull out of you. Your cunt muscles kept me in you. I shot my load in you,” I said.Diane gasped and straightened up pulling my cock out of her cunt. She gasped with shock as she noticed Amy beside me. Diane looked white with fear. Then, she realized she had sperm. Matt told her she could do what she wanted to do. The only stipulation is that Matt will be present for her modeling session. Anne asked Matt if he was OK with her exposing herself to another man besides Paul. Matt had no problem with this as long as she wants to do this. She told Matt to set it up. He told her that she would have to call Paul to make the arrangements.It took Anne about 3 days to get up the nerve to call Paul. She called his cell phone and with strained voice she told Paul who.
