2 years ago, my wife Shar and I started to have sex with our divorced neighbor, Jill, her 18 year old daughter Dian, and Dian's boyfriend Don. Dian and Don have since broken up, went their went their separate ways, and moved to attend college out of state. Jill is still a regular breakfast visitor with Shar and I and having lots of sex. Jill tells us that Dian is fully embracing her bisexuality and is introducing lots of college girls to the pleasures of bisexuality...
Last week, Shar and I decided to take Jill to go buy some erotic magazines. While in the lesbian isle of the erotic magazine section of the bookstore Shar finds a wallet dropped on the floor, she picks it up and sees the ID says the owner is 20 and is named Linda. Shar puts the wallet into her bag and continues shopping. After a while in the store we leave with a few magazines while I went to a video store to see what erotic movies they had in stock, Shar and Jill went into a erotic sex shop. Shar met me at the car with a bag full of toys followed closely by Jill. That night, Shar told me about the found wallet, I told her that she should call the phone number on the ID. Shar called, and told Linda that we found her wallet, and that she should come pick it up tomorrow, Linda agreed. After that Shar showed me what she bought in the erotic sex shop, a few dildos and a strap on. Shar told me that they are for Jill and Dian when she visited...
The Next day, when Shar and I were eating breakfast we heard the front doorbell ring, we knew it wasn't Jill because she now has a key and welcomes herself in; so Jill slipped on her housecoat and went to the door while I continued eating. A few seconds later I hear Shar say "You must be Linda, we have your wallet in the bedroom come follow me." As Linda followed Jill to the bedroom she can see my fully erect cock through the glass top table and was clearly shocked that I was naked in front of complete stranger. As Linda entered the bedroom with Shar, she saw the strap on the bedside table and was turned on but clearly trying to hide it from Shar.
Shar asked Linda to have a seat on the bed. Shar noticed the Linda wouldn't stop staring at the strap on, so Shar asked if the strap on had any effect on Linda. Linda said that she came from an extremely religious family and was raised that any sex not between a married man and a woman is a sin. But also said that she has always wondered what sex is like. Shar leaned into and asked Linda if she has ever kissed a girl. Linda replied by saying that she has never kissed anybody other than family. Right then Shar gave Linda a short but passionate kiss. Linda's eyes got big, her nipples got hard, and her pussy got wet. When Shar broke the kiss Linda immediately kissed Shar back. As they were making out I entered the room quietly and sat in the chair in the corner of the room.
