They were both very nervous the next time the grandparents visited Jen. Ben considered not going but knew this would look very strange. Things went very much as they had the previous time until the nappy had been changed. Betty said she needed the toilet and offered to put Jane down for her sleep. As her footsteps could be heard climbing the stairs Jen took up the exact same position, without the baby this time, with her bottom high in the air. Ben stunned by this and further surprised that her wet pussy was this time not covered by any clothing. He entered her holding her hips and very quickly got into a rhythm that was far more forceful than the previous time.
Jen was very excited as before but this time there was no immediate orgasm just a lovely building up of the arousal. Both panicked a little when they heard a door close upstairs but they realized that it was Betty going into the toilet. Jen intensified her caressing of her clit and she knew she was well on the way. Half of her concentration was on questioning how long they had before Betty returned. When she heard the toilet flush the panic this created in her triggered her to explode in orgasm. He followed on immediately and they were back in position, if looking rather flushed before she was half way down the stairs.
The next couple of visits saw Jen being even more "careless" about covering up. Ben had an erection throughout. They were both very frustrated that there was no opportunity for them to have any sexual contact. This changed at the next visit when Betty suggested that she and Ben did some shopping to help Jen out. Jen said that would be really helpful but could she ask Ben to do some things that his son would normally do around the house. Racking her brain she mentioned light bulbs and mending a plug. It was agreed that when the baby was settled Betty would go shopping while Ben stayed and helped out.
Jen rushed through the feed and nappy change desperate to spend time alone with her father in law. Ben had trouble hiding his excitement as he closed the front door while watching his wife drive away. He wasn't surprised to find Jen on her knees completely naked with her bum stuck up high. However he had other ideas about what they could do given they had plenty of time. Rather than immediately reject what was on offer he knelt down behind her before spreading her cheeks wide and finding the very heart of her anus with his tongue. There was great surprise in her response but very quickly he realized that there was no fighting against his action. He had noticed before that her bottom always appeared relaxed and very open. Very quickly her breathing changed and her sounds of arousal were very clear. She was almost disappointed when he moved away before entering her ready pussy. As usual they were both soon getting close to climax. Again as he withdrew and moved away again she complained bitterly. His now lubricated prick was quickly offered up to her anus and she pushed back to ensure penetration. Despite the fact that for once they had plenty of time his cock deep in her bowels sparked her to cum hard and violently. This in turn triggered him to explode pumping while he was fully buried in her.
Jen was surprised yet again when Ben rolled her onto her back and, pulling her legs apart and back, found her erect clit with his mouth. No one had ever gone down on her after fucking her. He reached up and took both of her huge nipples between his fingers. When his fingers did the right things milk sprayed everywhere. As her clit had not been involved with her first orgasm it was not hypersensitive. His experienced mouth and tongue felt perfect and she rode waves of pre-orgasm excitement. Jen didn't want it to end even though it was only going to end with her having a second climax. When it did arrive milk sprayed from her nipples and she broke down in tears as her body shook violently time and time again.
It was not the last time Jen enjoyed sex with her father-in-law even if it was one of the most spectacular times.
