You have some time right now.

This has taken not even a tenth of the time that you put aside for this as Fiona has taken this way better then some people have. Some of the ladies when coming out of the bimbo state have taken a much longer time to adjust to the new way of things working, even some of the ladies who had not caught the virus and had to be brought over found it hard to adjust to this new way of life as well. You had thought with Fiona having such a hard time she would have taken a lot longer to accept how things are in town now and more then likely all over the world for those who have survived this epidemic so far.

It is also clear as day while she is a little freaked out about the whole been with a woman thing she is still one horney lady who is weighing her options for how to relieve the tension. You should also be honest that due to some maths on your part that this is around the best time to put a bun in Karen's oven and had set some time aside to do that on this trip out. Hence why you have been slowly undressing Karen and caressing her on the bed as you talk with Fiona who has been watching in rapt fascination the whole time. Not just to show Fiona how different things are now in town.

Karen is now out of her cloths, really enjoying the attention you are giving her nice firm breasts and the really hard piece of meat that is currently rubbing up against her back through your pants means she is going to be getting some very soon. Slipping out of your pants and laying down on the bed you lift Karen up in the air and Fiona lets out a faint gasps as she sees you erect throbbing cock as you lower Karen slowly onto it. Letting out a low moan of pleasure as she sinks onto your cock Karen soon finds herself with a massive cock buried all the way into her womb with how wet she is.

Orgasming from this Karen arches her back and lets a cry of passion as she cums hard, letting Karen ride out the orgasm while she rides your cock how she likes it, having found it best to let her take what she needs from this in the past Karen can get a little cranky if you do not let her fully experience the orgasm. After grinding on your cock for a good ten minutes Karen has worn herself down enough she slumps back onto you to take a breather leaning in you tell her the good news. " Karen my dear it is time for what we discussed a while ago if that is still what you want". Hearing this Karen is energised once again and manages to lean round far enough to kiss you and say do it.

With all the factors now in play you remove your cock part of the way out of Karen's womb due to knowing just what is about to happen, Karen now is the one to get a shock as she can feel the dick inside of her getting somehow bigger. Fiona has been watching the two of you go at it after getting off the bed, taking a seat to one side to give you two space and give herself a little space to get comfortable as even she has found it highly erotic watching her sister get fucked. So seeing your balls and the base of your dick seem to start to grow she is more then a little surprised by this and can only stare as it unfolds.

On the other hand Karen is moaning in a another way as she feels so full from the size of your cock in her now and she is panting hard as she tries to get comfortable. This is all moot as about sixty seconds later your new and improved balls send blast after blast of semen into her womb, Karen feels and hears this happen while Fiona sees and hears it happen. The first blast completely fills Karen's womb the next cause her stomach to begin to grow, by the last blast of semen Karen looks about six months pregnant now as you hold her up otherwise she would have collapsed by now and all she can say is a mumbled thank you.
