The one you thought you would be fucking the most.

Fiona is staring at her sister in wonder and can only remember how great it felt the last time you fucked her like that, even if it was different in some ways. While things have gotten a lot bigger due to you breeding Karen it is nothing like the hulk state you go into and was in when you did the others in the barn and for which many a woman in town wants a go on. Letting Karen down gently she manages to prop her butt up under a pillow and smile at you as she starts to recover, but before she does she gives you a subtle nod towards her sister.

Kissing Karen then whispering you understand you get off the bed, only to find Fiona with no pants on in a giant chair of some sort and a couple of fingers plunged into her pussy having just tried to get off after watching her sister get knocked up. With only a few seconds of shock you really should not be surprised by this sort of thing more as in one very odd session you did a mother and daughter at the same time as they just could not be separated but that is another matter entirely.

Fiona sheepishly stops what she is doing and just gives you a look of oops sorry that she got caught kind of look and all you and Karen can do is laugh or try not to laugh anyway but fail in your case. Walking straight up to her you take her hand and move it to one side then take both her legs and spread them apart before spreading her pussy lips with your cock. Moaning deeply as your cock goes in Fiona has to grip the back of the chair and push back as while it is not as big as what fucked the first time it is still more then she is used to and the fit is still tight.

Hooking your arms round her legs and gripping her thighs you spear more and more of your cock into Fiona's pussy slowly making your way deeper into her, moaning as your cock invades deeper into her Fiona is experiencing a lot of joy from this as it is not as violent or rough as the first time yet still it is clear she has no control over what is going on. Even before all this went down Fiona liked it when her boyfriends took charge in the sex department and this is just making her time so much more enjoyable, she was embarrassed when she told the Doctors about how she felt when you ravaged her in the barn. But she was shocked when the doctors told her that many of the women now felt the same way and not one woman minds the fact they like to be dominated now.

You of course have no clue that so many of the women you have had sex with now like to be controlled when they have sex as no one has thought to tell you as they simply do not think it is needed as in no way can you not take control when having sex at the moment as the primal instinct in you is far to strong so why bother.

Having managed to get a very good angle as you drive your cock into Fiona she opens up completely, allowing your cock to make rapid progress as it slides into her cervix. Fiona can only cry out as she orgasm from the piledriver her cunt is receiving as you carry on forcing your cock right up to her wombs entrance. Panting as your cock presses up against her wombs entrance, Fiona lets out a deep groan as her wombs entrance allows your cock to enter her womb. Slowing down now for Fiona as she is basking in the orgasms she is having from your cock popping into her womb and the subsequent fucking she is getting.

Fiona at the end of the day ends up just like the last time just not anywhere near as full of your semen as you cum directly into her womb sending her into such an orgasm she collapses and passes out for a little bit. Karen giggles as she sees her sister in her current state, " well that is not something you get to see every day now help a girl out and get me over to the bathroom will you Tim I had best deal with this now I can move some what". Snorting yourself now you help Karen make it to the bathroom only to return to the bedroom to find Fiona still out like a light with a happy look on her face, collecting your stuff you leave the two ladies to it and head on downstairs.
