Too Good To Pass Up

Connie showed at her high school friend's house after a phone call.  She was a rich widow and drove up from Texas. She hadn't seen her friend Bonnie since high school. The two women have a lot in common since both like crafts and going to thrift stores.  Bonnie invites Connie to stay overnight and then keeps encourages her to extend her visit. Since Bonnie was handicapped due to a car accident, Connie started doing the cooking, cleaning, and grocery shopping.
She also took Bonnie anywhere she wanted to go since Bonnie wasn't able to drive any longer. She was like a dream come true. She was even generous with her money since she was wealthy. Bonnie's husband Jack questioned her motives though and wondered what she wanted. The problem was that Connie and Jack had a strong sexual attraction to each other.  She kept suggesting that they get something going.  But Jack didn't want to jeopardize his marriage to Bonnie.
Then one day Connie made a strange proposition.  She was willing to keep staying with them if Bonnie would let her sleep with Jack.  It was just too good a proposition to pass up since Bonnie didn't want Connie to leave. This is an erotic romance.
