The words playground and sleeping mother had caught my attention though. I walked on to the line of parked trucks before turning around to look. I ha... turned around just in time to see a very shapely adult female butt disappear into the back seat. On the passenger side. I saw a very cute girl of about eleven or twelve getting out of the car. A little old I thought for the playground equipment in a rest area I thought, but exactly the age I love to fuck. I watched to see where she went and sure. It won't let go of you. It's there all the time, just like you are with me all the time. I don't have a minute that I'm not thinking about you and wondering about you. Even when I'm asleep, you're in my dreams. I can't help it. There's nothing I can do about it. I'm in love with you, Catherine. I want to marry you. I want you with me for the rest of my life. Yes ... yes ... I meant it then and I mean it now."Both of us had put our coffees in the holders or otherwise there would have been a pair. A huge wave of guilt fell upon her. No matter how long she stayed under the shower, she could not wash away the filthy desires scorching through her mind.She felt relieved though. At least the painful urge was gone. Maybe she had gotten rid of it for good. If such a powerful orgasm hadn’t then what would? If such a powerful orgasm couldn’t, then she was surely doomed. But she didn’t want to think about that right now.She now had to bath again. Movements that were, only a few minutes ago. Keeping everyone safe is more important right now.It’s less of a big deal this week anyway, since Katie’s on her period. Yes, I know we could do it in the shower and not make a mess, but we don’t have the freedom to do it in my house like we would at hers. We do what we have to do. She treated me to a blowjob when we sneaked off to my room on Tuesday and I’ve rubbed her pussy a few times when we thought we had time. Katie likes to cum when she’s on her period, she says the orgasms help with her.
