Everyone in this story is over 18.
Now that mom was my girlfriend, I wasted no time testing her promise that I could fuck her whenever I wanted. As we spooned naked that night, I woke up with her in my arms with my hard dick pressed against her ass like before. But this time I slipped my fingers around to arouse her, and she began responding, either awake or asleep, I really didn't care.
When she was wet enough, I slid my dick down between her legs and she parted them just enough to invite me in, otherwise appearing to sleep through the whole thing. I just stroked and soaked and came softly and gently, then fell asleep again, still inside her.
Yes, I could fuck her whenever I wanted.
The next morning our pillow talk was French kisses and refreshing that hickey on her neck, legs involved and twisted, but too slow and easy to turn to more just yet.
Once it seemed time for talking, I said, "Last night, when I fucked you for the first time, the tattooed girl was watching."
"Really!" She sounded more excited than shocked.
"Yeah, she was close enough, I'm sure she saw and heard everything."
As if summoned, there was a knock on the RV door. I rolled away from Mom and peeked through the blinds. It was the tattooed girl. She had a tray of food in her hands. She turned towards me when she saw the blinds move.
Mom pulled the sheet up over herself and I slipped on my gym shorts. I opened the door and looked down at her.
"Good morning!" one of us said.
She leaned to look past me into the room. "I thought your mom might like some banana bread. I just baked it."
I saw that the tray held the bread, and three cups of coffee. "Looks like you brought enough for all of us, come on in."
I asked her much later what her first impressions of us had been, both when we first arrived, and when she entered our RV for the first time. She told me then that when she first saw us, she knew exactly what we were into, and found the idea of it, and of my mother, irresistible. Then this morning, the sight of me still in bed sweat, my mother with the sheet barely covering her boobs, her hair tossed in every direction, the bright red mark on her neck, and the smell of us in the air, cast a perfect spell on her.
We both sat on the bed. I wanted to see what kind of power I had over Mom, at least to do the things that she wanted to do anyway. "Drop the sheet, Mom, let her get a good look at you."
She let go of the sheet and it floated down below her breasts. She reached for a slice of bread and ate it without saying a word. We all just ate, for now.
I pulled the sheet the rest of the way off my mother's body. It was so erotic for her to be lounging there naked, the girl fully clothed, and me in just my shorts. Mom drew one knee back, exposing herself more fully.
Mom looked at the girl and instinctually asked, "Where's your mother, child?"
