Jen's husband had left her just before the baby was born. She had always been close to her parents in law and decided that she wanted them to be able to see their first grandchild grow up. Baby Jane was five months when a visit by Ben and Betty changed many things.
Ben and Betty visited in the morning when Jane had her longest time awake. Near the end of their visit Jen was breastfeeding the baby as she had done in front of them before. She was never very coy about this and often did not cover the boob she had just finished feeding Jane on when transferring her to the other. Jen had always had boobs that were embarrassingly small in her opinion but now they looked very full on her small frame. Her nipples had always been big and sensitive and now they were huge and super sensitive. On this particular day she noticed Ben paying more attention to her boobs than usual. For some reason she was pleased with this and gave him every reasonable chance to get a good view of them.
As she finished feeding baby Jane she said that she was going to change her nappy and then put her down for a sleep. Ben and Betty said it was time to go and headed for the door. Jen had finished changing the nappy when she heard the front door close. The combination of breastfeeding and Ben's attention had got her sexually aroused and she did something that, although she was ashamed of, she had done on a number of occasions. She knelt over her baby and encouraged her to latch on to her dangling nipple. She then reached back and started to masturbate through her knickers.
Ben had left his phone where he had been sitting and while Betty went to the car he walked back to the lounge. His view as he got to the lounge door was from slightly behind. There was no doubting what he was witnessing. He nearly kept quiet but decided instead to announce himself.
"Do not stop doing what you are doing it is the most erotic sight I can ever remember seeing."
Her hand froze where it was and the rest of her froze too.
"I said do not stop what you are doing."
He had crossed the room and was just behind her when she gave an anguished moan that he had no idea the meaning of. Even though her knickers covered her he could see she was aroused. He had had a partial erection for the last half hour but this had taken seconds to become fully hard. He simply pulled her knickers aside and offered his prick up to her pussy. There was no attempt by Jen to move away and when he pushed forward her wet pussy welcomed him with little resistance and no complaint.
