You enter your bedroom to find Sammy sleeping on your bed, wearing some of your clothes. She apparently showered while you were out. Your top was even a bit large on her, given the difference between your cup sizes. You just sigh and take off your skirt and Sarah. You forgot about removing your heels though. It is late at night, and after emptying out Sarah and putting her back on, you join Sammy in your bed.
Morgana stood by idly, as she didn't know what to do. While she is technically a bike, she is also a person, so you felt bad just leaving her as is. So you let her join you in bed. She seems delighted to hear this, but turns down the offer as she knows what will happen if she did. She would likely end up either breaking the bed, or getting everything all dirty.
So Morgana just returned to her bike form and leans to the side on her clit stand, shutting off until she turned herself on again. This made you chuckle. But as there was little you could do about it, you just let her be.
Thw moment you got into bed, Sammy turned over in her sleep and grabbed you by the waist. In one quick motion she had your back facing her and her cock burried deep within your pussy, and all while she was still mostly asleep. You can hear Morgana tried and bairly managed not to laugh, as that would have blasted her horn while she was in this form. She had seen it all happen as her head had been turned to face you this entire time.
You roll your eyes and lay back down as you feel Sarah tighten her straps around you like she usually does when you sleep together. This all being said though, you don't even bother removing the cock from your pussy. It isn't like you were against it being there in the first place. It was just amusing how Sammy had made you her cock sleeve while she was sound asleep is all.
The next morning, you wake up to find Morgana kneeling beside you, running a few of her fingers through your hair. It was kind of surreal seeing her shiny polished body, yet feeling how soft her skin was. She looked as if she was made of plastic or metal which had only been detailed to look like skin. Something that you must not have realized last night since you were tired and it was kind of dark outside.
Her front tire was not on her body though. And was sitting down in between her wheeled feet so that she could turn her torso more freely. You also realised that she was completely naked, and that her outfit was literally painted onto her.
You grin and grab one of her tits while she does the same, slipping your left tit out of Sarah's straps. She then begins suckling on it. To your surprise, you actually could feel a liquid pass through your erect nipple into her mouth. You didn't know when you began lactating, but after thinking about it, with tits the size of large watermelons and then some, it isn't too much of a surprise for you. Now that you were thinking about it, you also wondered what was your actual cup size.
You just let Morgana drink for as long ss she wants too. It feels good and you also kinda wish to try it out too. She moves to your right boob, so you grab your left tit and manage to bring your nipple to your mouth and give it a suck. Your eyes widen in surprise as your milk sprays out into your mouth. It actually tasted really good too, so you both just continue to drink in silence for a while.
The interesting thing about your boobs is that even with their size, they still retain a perfect amount of firmness and a complete lack of any significant sagging too. You wonder just how much milk you have in you too, as you can't seem to empty either boob, no matter how much the two of you swallow.
After a few more minutes, Morgana strops drinking and wipes her mouth clean. It only now occurs to you that you just have basically filled her up with fuel. She obviously doesn't have a normal fuel tank, nor even a place to stick the nozzle into, besides her mouth and the hole in the back of her neck. You figure that her stomach now is the tank, and that she might run exclusively off of fluids which your body produces. In other words, your cum and breast milk. If this is the case, then you were looking forward to your daily breast feeding sessions.
