Read "An Evening with Mrs. Lasalle" and "An Afternoon with Mrs. Lasalle" first.
For the remaining Sundays of the summer, I met Mrs. Lasalle at the auto shop. This is not that story. Let me just say that she taught me a few things.
At the end of August, I was having my 19th birthday. She wanted to celebrate my birthday by meeting me for dinner instead of having me visit her at the garage. Mrs. Lasalle gave me an address to meet her the following Sunday, late in the afternoon.
I biked to the address and arrived around 4 pm. It was a small house. I locked up my bike and went up to the front door and knocked.
A lady came to the door. "Willy?"
"Yes."
"Don't you recognize me?"
She had long natural curly hair. I did recognize her. But it had been years since I had seen her. "Aunt Beth?"
She laughed. "Come in. I am not your aunt Willy, just call me Beth."
She was Mrs. Lasalle's sister. She was the one that came over on all the birthdays. She liked to party with her sister and drink and horse around. She almost slapped me when her sister slipped her hand between her legs from behind and pinched her crotch. She had turned around and I was standing there, and she thought it was me. I called her Aunt Beth because that is what Kevin called her. She was a little shorter than her sister. Less curvy. Definitely smaller breasts. Her hair and the shape of her mouth and nose and her eyes were all similar to her sister. She looked a few years younger than Mrs. Lasalle. I would guess she was between thirty and thirty-five.
She was cooking dinner in the kitchen adjacent to the living room and she talked to me as she cooked. She brought me a drink and I turned on the TV. She came in a couple times to talk. I sat and slowly sipped my drink. What she was cooking smelled good, but I was a little disappointed. I would have to sit through an awkward meal instead of having fun with Mrs. Lasalle at the auto shop.
Mrs. Lasalle arrived. She was wearing the summer dress I liked so much and carrying a small cake. "Happy birthday Will."
"Hello Mrs. Lasalle."
"Mrs. Lasalle?" Beth questioned. "How formal."
"Will is very respectful Beth."
Beth carried the cake into the kitchen and Mrs. Lasalle sat on the couch close to me. I kept switching from staring at her in that tight dress and turning my head to see where her sister was in the kitchen. Mrs. Lasalle was smiling. She had a lecherous look on her face like when we were together, and she was enjoying herself. She put her hand on my leg and started moving it towards my shorts. When her fingers slid under the bottom edge of my shorts, I put my hand down on hers stopping it. I looked back to the kitchen. Beth was busy. Mrs. Lasalle forced her hand a little farther under my underwear and touched my balls and the base of my shaft. I just watched her for a while, unable to ask her to stop. When Beth started coming into the room I twisted and pushed her hand away. Beth handed her sister a glass of wine and then sat down on a chair facing us. I crossed my legs and pushed my hardon down.
We sat for a while and talked. Beth asked if I wanted some more iced tea. I said no. They drank their wine and continued to talk. Mrs. Lasalle asked about dinner.
"It's all done. Just waiting for the stuffed peppers to finish. It should be fifteen minutes."
"Fifteen minutes. What should we do for fifteen minutes?"
"What were you doing when I walked in?" Beth looked straight at me. I must have been a little flushed when she walked in.
"We could do that." Mrs. Lasalle said. Then she put her hand back on my leg and slid it back towards my shorts. I stopped her with my hand. I didn't want to stop her; I just reacted because Beth was watching us. "Will. Let's do what I want." She said it in a way that she talked to me sometimes. Forcefully. I had to do things her way. She had made that clear to me the first time I met her at the auto shop. Our third Sunday together, she failed to show up. I called her the next day, and she was furious. The next Sunday, she made me do something humiliating. Something I don't want to write down. After that I always obeyed.
I let go of her hand and she slid it up my shorts as I spread my legs and sunk back on the couch. She got her hands on my shaft again and gently groped the bottom part of it. My eyes rolled back, and I groaned. I opened my eyes. Beth was staring at me over her wine glass. Mrs. Lasalle stopped and told me to stand up. I stepped out of my shorts and underwear. Then she told me to remove my shirt. I did. She moved me until I was standing between the couch and chair that Beth sat on. Mrs. Lasalle turned me one way then the other. Beth looked up at me. I felt embarrassed, but I was obviously turned on and my dick was rigid.
"What do you think?"
"He's grown nicely." Beth said.
Mrs. Lasalle guided me back to the couch and I sat down. She got off the couch and kneeled between my knees and started to lick my cock. Beth moved from her chair to the couch and sat next to me facing me, one hand still holding her wine glass. Mrs. Lasalle kept kissing my shaft and rubbing her lips against the head. She used one hand to fondle my balls and touch my legs. Beth looked down at my cock mostly but occasionally watched the pained expression on my face.
From the first time at the auto shop Mrs. Lasalle realized that I could get overwhelmed easily when we started to fool around. She had to take her time, or I wouldn't last. She got good at making me last. I didn't doubt that she would keep it up until dinner was ready. She kept teasing me, never putting it in her mouth and sucking it hard. Usually, we took breaks and we kissed, and I licked her nipples, but this time she remained fully clothed. She stayed right on it, licking and snuggling against it. She looked up at me and said "Beth wants to see it. She wants to watch when you do it."
I was confused. Beth was already watching me. What did she want to see? "Um ok."
Mrs. Lasalle lowered her mouth and took my shaft in. She raised and lowered, and I felt a lot of wetness, as if she was deliberately salivating. Then she got up and squeezed in beside me on the couch. I was between the two sisters and Mrs. Lasalle reached over and grabbed my shaft and started stroking me. This was the first time she used her hand so forcefully on me. It felt way better than when I jerked off, but it was nothing compared to when she used her mouth. She was doing it steadily though, and I felt myself building up. I sunk further into the couch. She slid her hand up and down. She was jerking it faster and I felt my body tense. My legs straightened and then bent pushing against their legs. Mrs. Lasalle put her leg over my lower leg. I watched the head of my penis disappear into her curved palm and reappear over and over. Beth was watching me intently. She was wearing jeans so I couldn't feel her flesh, but the fact that I was pressing my leg against hers was exciting. I looked at the tshirt she was wearing, and I saw that her nipples were hard. I turned from Beth to Mrs. Lasalle who was watching her hand slide up and down. I looked down. She was stroking me fast and my engorged head appeared and disappeared in a blur. I squirted. I grunted. I felt something hit my chin. I squirted. She kept stroking me even as I spasmed. A rope of cum landed on my chest accelerated by the pulling of her hand. I kept spasming until I couldn't stand it anymore and I clasped down on her arm stopping her movement. By the time I caught my breath I realized I was covered in cum. She had pointed up towards my chest as she stroked me, and I had beads and streaks of cum from my belly button to my chin. I sat there catching my breath. Finally, Mrs. Lasalle let go. Beth stood up and walked away.
"That was good Will." Mrs. Lasalle stood up. "Go get cleaned up. Take a shower." She guided me down a hallway to a bathroom where I took a shower as she washed her hands. When I got out, she had my clothes waiting for me. She told me to come to the kitchen.
I walked into the kitchen. The table was set. I sat down and I looked away from Beth. I concentrated on the food, which was very good. The two sisters talked like I wasn't there for most of the meal. Beth finally asked me some questions. What had I been doing for the last few years since she had seen me? Was I playing sports? Did I have a girlfriend? Before I answered the last question I looked over at Mrs. Lasalle and said a quick 'No'.
"Beth knows what we do." Mrs. Lasalle said. "She knows about our Sundays at the auto shop, she knows about me sneaking down into the basement. Beth and I tell each other everything."
"If you can't talk to your sister, who can you talk to?" Beth added. "I have to admit, the stories I've heard the last two months have been wild. I had to see for myself."
Mrs. Lasalle took my hand. "It's your birthday. I've planned something special for you."
