He and his wife had been planning to get her sister to be their surrogate mother since they had been unable to become pregnant on their own, and her sister had been nice enough to offer. So the plan was to take her to the clinic to have the procedure done, but the husband had another idea. wouldn't be so much easier to just fuck and get his wife's sister pregnant the old fashion way? Seemed like a lot more fun, so he told his wife's sister that he and his wife had talked about it and decided that it would be better if he just put his semen inside her the easy way. just with his penis. in her vagina. and really they were going to need to fuck to get the cum to come out. So she agreed and let him do it. and really, it was a lot more enjoyable that way than going to the clinic!
