Ever since that day, my wife got closer and closer to David. Of course, she would inform me every time and also on what she planned to do and what she did afterward. I agreed almost all the time. She would meet him when he does his gardening or just to talk over the door. Most of the time, she would be braless and would wear enough to show some cleavage. She would also time her shower so that she could make herself look wet before talking to David. David grew more and more comfortable with her. In fact, I was also talking more and more with him and his wife every time we met. Nice family indeed.

One day, things changed a lot faster than expected. As usual, my wife was feeling horny and let me know that she wanted to tease David a bit. I let her go and told her to bring her phone and update me on anything naughty. Feeling extra naughty, she put on a push-up bra and a lace nightie and was wearing a cotton brief. She also wore a g-string that she pulled up to show at the back, above her shorts.

"Hi David, may I come in? I got some problem with this device." she brought along her vibrator. The vibrator was common in shape and can pass off as any massaging device.

"Oh sure come in. What is this thing?" David asked innocently.

"Erm, it's a massage device. My husband got it for me. It's not working." She said playfully.

"Hmm ok." He said as he began examining the device for switches etc. he saw the catch and opened up the battery compartment. He then grabbed a set of batteries and replaced them. With another switch, the thing came alive.

"Oh. There, it's working now." He said as he passed the vibrator to my wife.

"Oh yay! Thanks so much, David" she said as she proceeded to give him a hug. He was taken by surprise and for once, he felt a pair of soft big boobies on him.

"You're welcome." He said as he hugged her back. He hugged her tight and it seemed more like an embrace than just a friendly hug.

My wife knows that he got the hook and began hugging him tighter, gyrating her hips slowly against his cock. "Thanks, David dear. You have helped me a lot." She said, changing her tone to a sexy sultry voice. Unknowing to David, my wife had left the speaker mode on and placed her phone on the table. On the other side of the line was yours truly.

"Now I would like to return you the favor." She said as she pulled David by the hand into Joe's room. David just followed, as if in a trance. "Stand there. Don't move." She said, as she lay on his son's bed and erotically opened her legs. Taking the same vibrator, she slowly massaged herself, starting from her legs.

"I don't think we should..." He said.

"Sssssshhhh... just enjoy... no one will know..." She said seductively.

She then began to rub her body and slowly lifted her nightie, exposing her torso.

"Mmmmph..."

She then slowly removed them entirely, revealing her big breasts. David tried to look away. My wife then stood up and pulled him closer. She held him by his hands and slowly directed them to her breasts. "I know you want these. I want you to feel my breasts. Something that your wife does not have." She smiled. David was in total shock, yet he was filled with ecstasy at being able to grope such large breasts.

"Oh gawd..." He murmured.

My wife let him grope for another 5 mins as she slowly inserted the vibrator into her. After that, she lay down back on the bed. "I want you to stand there and take off your shorts." She instructed. David was hesitant but slowly, he removed them. As he wasn't wearing any undies, his erected member was now showing. He slowly began touching himself.

"Ahhhh good. Tell me David dear, how long have you not had sex?" She asked.

"A... bout more than 10 years ago."

"Mmmm... And how long have you not touched yourself." She asked.

"Since last year..." He said.

"Tell me honestly.." She said seductively again. "When was the last time?"

"When you asked me to help you with the cockroach problem at your house." He said reluctantly, slightly ashamed.

"Oh... That day huh..."

"Alright, I'm going to reward you for your honesty. But you promise not to tell your wife or my husband ok?" She said

"Ok..."

With that my wife got up and went to give David a blow job, which caught him by surprise.

"Oh, gawd... Oh gawd..." He exclaimed.

"Mmmm... you're so delicious... do you like it..." My wife asked.

"Yeah... Ooh... Yeah..."

"I bet this is the first time right?" She asked again.

"Yeah..." David replied, his eyes still closed.

"Good. I'm going to make you cum. And I want you to come on my breasts." She said before she swallowed his cock again and again.

"Oh yeah, I'm cumming... I'm cumming... I'm cumming..." David exclaimed as he pulled out his cock from my wife's mouth.

"Cum on my breasts... Cum on me..."

"Aaahhhhhh...." David said as he cummed on her breasts, some even landed on her face and mouth.

My wife said his cum was stinky but thick. She said that she continued to suck him again after that until he was totally limp. "Mmm, that was good. This was all to thank you for your kindness and your help." She said as she gave him a peck on his cheek. What a slutty wife.

"I'm going to leave now. But remember, cannot tell your wife and my husband. Promise me this and I can do more with you, whenever I feel like it." She said as she got up and left poor old David on the floor. That night, wifey and I made an agreement that she can only do blowjobs with David. After that, she has to satisfy her pussy with me. We don't want to spoil a family. Not too much 😈.

Next up, the story will be on David's son, Joe, and the lessons that my wife helped to teach him.
