Both of course

Having moved over to the railing Ava's tits are already enlarging to a very large size as you can see by how she struggles to remove her shirt but just manages to get it off as her her tits reach the double G size. Groaning as her tits get bigger you move over to come up behind her to begin massaging and milking her tits but as you approach her you cannot help but watch her ass thrust backwards, seeing this it gives you a very naughty idea.

Taking your cock in hand you thrust it in to your aunts pussy causing her to nearly mount the railing in shock, "dam it Timothy you are supposed to be helping me with these god dam air bags not mounting me again". Leaning over her shoulder as you move deeper inside of your aunt, you take her melons in hand as soon as you begin to massage her tits she moans and orgasms like crazy . The intensity of the orgasm makes your aunt to go limp, causing her to be only held up by your cock in her pussy and her massive tits being propped over the railing. Due to this gravity has helped **** your cock deeper into your aunt passing her cervix and lodging itself in her wombs entrance till you move forwards in an attempt to help her and fully this makes it pop all the way into her womb.

Moaning and groaning as you milk her tits your aunt is barley with it as you also fuck her, granting her multiple orgasms and an even bigger one hits her as you again cum inside of her flooding her womb with seaman and causing her to appear heavily pregnant when you are done cumming in her again. Unable to pull out of her as you have to keep milking her your cock is locked inside of her womb, the cum having nowhere to go. Unfortunately for aunt Ava the movements she is making as she orgasms again and again is making you hard again. The sounds she is making as you milk her tits, the movements she is also making on your cock quickly bring you close to the edge.

Your aunt cries out as you reach another orgasm and explode inside her again, with her eyes rolling over and no longer making any sort of sense other then a low moan your aunt passes out as her belly expands to look like she is pregnant with triplets at nine months and her breasts now spray an almost continues stream of liquid finally deflating to an impressive 36DD.

With Aunt Ava now passed out and limp as a fish this allows you to pull out of your her womb finally, your cock pops out of her pussy and the seaman flows out on to the floor making a very large puddle. Helping your aunt to a more comfortable position as she begins to come round, blinking as she comes round Ava cannot believe what has just happened you have fucked her so well she can hardly move, her chest would make a pornstar proud and a scar she got a few years ago has just healed over completely. " Timothy what just happened between us is not something that should have happened young man".
