After 4 days of confinement, Lisa was allowed to leave the hospital and returned to Thomas's mansion. He had arranged for them both to go a health and fitness farm for the next seven days. Lisa complied reluctantly, wishing instead that she could stay with Richard. She wasn't overly concerned because she knew that no experiments would take place until at least one month from the day she gave birth, Richard would be quite strict about that. So, she thought, a time to be pampered and give her future husband a bit of sexual training...
Joe received a letter from an old acquaintance. Teresa Lehmann, the now proud owner of two beautiful twin girls had written. She was coming to visit England next week for 10 days, to attend an educational seminar and a series of lectures. Would Joe meet her for dinner one evening?
Joe was delighted to hear the news and wrote back immediately, asking her to call him and arrange the time and date. What Joe didn't know was that he had fathered the twin girls and Ms Lehmann wanted similar treatment on this visit...
Since the birth of her twins, she had given up her work and looked after the girls and her elderly frail mother in New Zealand. As she was approaching the ripe old age of 40 she had decided that if she was ever to expand her family, it had to be this year or never. A close check on her menstrual cycle over the last 3 months showed she was likely to ovulate next week and the trip was an ideal time to conceive and spend time with the only man she had ever loved, her handsome Adonis, Joe Jenkins...
Her flight from New Zealand was due to land on Sunday morning so she called Joe and made arrangements for him to meet her and take her to her hotel. With luck, Joe would screw her twice a day, every day until she returned home, hopefully with another belly fattening dose of Joe's testicles at work inside her...
Thomas and Lisa, meanwhile had arrived at the health farm and moved into the luxury suite that was to be their home for the next seven days. Lisa enjoyed a swim on arrival and then was treated to a Swedish massage and intensive facial treatment. That evening, positively glowing with health she dressed for dinner. She wore a long silk gown that Thomas had paid for but underneath she was dressed to thrill. She had slipped on a pair of satin French panties that clung to her like a second skin. In the reflection in a mirror she could see the outline of her still swollen labia. The panties accentuated the shape and she knew Thomas would nearly come in his trousers when he saw her. She added a pair of beige silk hold-up stockings and then stepped into her outrageous high heels. At nearly six feet tall, she walked into the dining room linked to Thomas's proud arm and enjoyed the sudden hush that always happened when people saw her. Feeling like a top film star she was shown to her table and sat down like the Queen of Sheba. The topic of conversation at every other table that evening was her and her beauty and grace and Thomas loved it...
During the meal, Lisa suddenly realised that she had overlooked something very important... Thomas would be screwing her that night and she was unprotected. Although she had only given birth recently, she knew that she could catch again quite easily. The last thing she wanted, was to start a baby with Thomas, she wanted to go through with Richards plans for her womb first. "Dummy!" she thought to herself. Why hadn't this danger crossed her mind before now?
After several large brandies and later back in their suite, Lisa decided that Thomas needed to explore the pleasures of anal sex with her, that should make sure that he didn't inadvertently dump his sperm into her vagina. She unzipped her long gown and stepped provocatively out of it, leaving it on the floor. Then she pushed him back on the bed and knelt down to unzip his trousers and remove his underpants. In a large mirror behind her Thomas could see this beautiful doll that was about to drain him of his male fluids...
Cupping his testicles with one hand she took his erection in her mouth and worked the muscles in the back of her throat around it. Thomas watched her backside and the satin underwear that adorned it. Her firm thighs exposed above the lace tops of her stockings. He was going to ejaculate too soon again. Just as he thought he could hold off no longer Lisa stopped and asked to wait. Strutting in her high heels she walked to the bathroom and slid her panties to her knees. Making sure he could see what she was doing, she dipped two fingers into a jar of face cream and smeared it inside the crease of her bum cheeks. Thomas's cock jerked and he only just managed to stifle his orgasm... what had his fiancée got in mind?
Lisa pulled up her underwear, walked back to his throbbing erection and clambered onto his prostrate body. Arching her back she pulled the pantie gusset aside and positioned the tip of his hard penis against her lubricated anus. "Do it inside my bum!" she gasped as if close to orgasm herself. Then she slowly dropped down onto him and allowed him to impale her...
