...your 'mom' (or your shapeshifting girlfriend or whatever) is wearing a black sexy, maxi dress. "So, what do you think about this dress, sweetie?" she asked with her seductive attitude and strikes a sexy pose. "Because I think this dress is going to suite your 'mommy'."
You drops your jaw as you're lost your words because you looked at your 'mother' who is now a perfect MILF in Black dress. You have never thought of your 'mom' this way before, but here you are! "Oh my goodness, my 'baby boy' just lost his word that see his 'mother' like this." she says as she's looking at your hard erection coming from your pant. “Oh my, looks like your little fella here is going to have some fun.”
As your shapeshifted girlfriend pulls you into the dressing room as you pull up her dress and she pulls down on your pants as you make out furiously. You grab at one of her enormous breasts as you insert your dick into her. As you thrust repeatedly your girlfriend let’s out hushed moans until you release a wave of semen inside her.
As you both clean up after yourselves, your shapeshifting girlfriend/mom closes you mouth gently with a dainty finger and kisses you. "So, my 'son', where will we go next?"
