My exhibitionist mom- book one/ chapter 3- mom watches patty come

(Note: This story is from Book One of the series, "My Exhibitionist Mom," by Jill Jacobson, available at Bookapy.com. ALL CHARACTERS DEPICTED AS OVER 18)

A week went by, and nothing much happened, and even though I could guess when my Mom was probably masturbating, I didn't try to catch her in the act. On Friday night I had Patty over, who was at the slumber party, and she asked me if I had seen Mom masturbating. I said no, and Patty suggested that we try to get her turned on and see if we can get her to do it. "Patty! You are a naughty girl! What would make you want to do that?"

"You didn't see her last time? She jerked off right in front of us! I had to wait half the night until you were all asleep before I jerked off myself!"

"Wow you did that right in the same room with all of us?"

"I sure did, and I could hear Alice do it too. I looked over and I could see her hand moving over her pussy, and her legs were straight up! I reached underneath myself and masturbated on my stomach. When I was ready to come I turned over so anyone could see me if they looked, but by then I think everyone was asleep."

"Wow I wish I had known, I would have looked. Why don't you show me what you did, and we'll leave the door open, maybe Mom will come by and see us. She usually comes up to take a shower around this time."

"Okay," Patty said, "but I'm going to jerk off using YOUR hand, the same as I did when I used mine."

"Huh?"

"Just hold it still and don't do anything, and just watch me." We had been sitting on the floor playing cards, and now she took off her jeans and panties, and she was nude from the waist down. She told me to lie down on my back and put my hand out, totally limp. She knelt over it, and started rubbing her cunt back and forth on my open hand. There was hardly any hair on it, and it was very wet.

She was starting to breathe heavily, and she pulled her blouse over her head and took her bra off. I was still fully clothed. She had very small breasts, but the nipples stuck out half an inch. She was on her knees now, grinding herself on my fingers. She took my hand and started rubbing it onto her cunt as she moved back and forth with her eyes closed. All of a sudden I heard footsteps coming, but Patty was lost in her own world as she moved her hips back and forth over my hand, while she was rhythmically pressing it onto her pussy.

My door was open about 4 inches and my Mom walked right by, glancing in, and then stopped to watch. I saw her out of the corner of my eye, and she was smiling. I feigned surprise. "MOM! What are you doing there!" Patty opened her eyes wide open, but she was too far along to stop.

"Mrs. Jacobson! I didn't know you were there!"

"It's okay Patty, I can see that you're masturbating, so just keep on going until you climax. You just pretend I'm not here."

"Mrs. Jacobson, I can't finish with you watching, I'm too embarrassed!"

"You just keep going, and you'll come pretty quickly, I can see your hard nipples. You're almost there, I can tell. Here, I'll show you mine, and that should speed things along." Patty moved a little faster against my hand.

"Mom, really?" I said, but she had already unbuttoned her blouse and pulled her perfect natural B-cup breasts out of her bra. She ran her palms up and down hard over her nipples to get them hard.

"Mrs. Jacobson, I can't help it, I'm going to finish now. I'm going to come. Oh my god this is so embarrassing to masturbate all the way off, in front of my best friend's Mother." Her hips were moving so fast now over my hand, but she was so wet and slick she moved over it easily. "I can't help it.... Here it goes.... Oh.... Oh, no, I can't help it, please don't look, Mrs. Jacobson, I'm going to come. Unh... Unh... UNH UNH UNH UNH!" My Mom just smiled at her. And she clasped her hands behind her head, moving her hips across my hand, staring at my Mom, and she climaxed surprisingly quietly, collapsing onto the floor, spasming quietly. It looked like she was crying. My Mom came over and sat next to her, touching her shoulders and talking softly to her.

"Ha, ha, ha! It's okay. You did it! You masturbated! You did very well, Patty, you should be proud to be so in touch with your body that way. I'm trying to teach Jill to be less embarrassed to explore her sexuality."

Patty rolled over onto her back, her nude body visible to us both. She even spread her legs to show off her wet pussy. My Mom kissed her cheek, then kissed me on the mouth, and got up and left the room. As she got up she stripped her blouse all the way off. I wanted to do myself right then and there, but I had another idea. "Wow, Patty, that was HOT! I'm excited myself right now. Let's wait a few minutes and see if we can catch Mom masturbating." It took Patty a few moments to recover. She put on my bathrobe and we played cards for a little while. It seemed quiet, and I winked at her, and we tiptoed out into the hall to see what we could see.
