Ask her if she want to have a date.

"Mom, I've been thinking, if you don't mind, could we go on the date?" you ask.

"Mmmm, not a bad idea, sweetie. I just love when you say that." your shapeshifting girlfriend/mom answers as she holds your face. "And y'know, you always want to date with an older woman, especially your own 'mother', huh?"

"Well, that because you look so beautiful and sexy that I couldn't resist you." you says as you're admire her.

"Teehee... you're such a sweet boy, sweetie." your girlfriend/mom replies as she gives you a kiss on the lips. "Anyway, sweetie. why don't we get up and head to the shower and then change our clothes from our room, okay?"

"Sure thing, mommy." you say as you both get up and head to the bathroom with each other. Then, you both step into the shower as you turn the water on and then wash yourselves with each other body. After a nice shower, you both step out as you both take the towels and clean each other body. "Sweetie, get dress especially something nice, okay? I'll go to my room and try something special." your 'mom' says as you nod and give each other a quick kiss. "Anyway, hurry up before we miss our date."

With that, you both separate as you go to your room and pick up your clothes to. A few seconds later, you finally got dressed and head out of your bedroom and meet your 'mom' in the living room as you saw your 'mother' how beautiful she is in scarlet red dress, and that beautiful makeup on her face, also a red kissable lips on it, she looks like a sexy vixen. "Wow, 'mom'. Y...you look great on it." you said as you amaze your girlfriend/'mom'.

"Teehee, thank you, sweetie. You aren't half bad, you look quite a handsome man. Like you date a girl in the prom." your 'mom' replied back. "Okay, now that we're both dressed, I say shall we go on the date?"

"Yes, we shall my lady." you flirt at her.

"Aw please, stop acting like a gentleman, sweetie. I'm your 'mother' and your secret girlfriend, not some elegant English lady." your 'mom' teases you.

"I know, 'mom'. Plus I couldn't resist that you're so beautiful." you reply back to her as you both hold each other and go to the garage as you pick up the car so you can drive with your 'mom' on the date. "So sweetie, where do you think we should go, the mall, the movie theater, or the carnival?" she asks as you're thinking, on the other hand, you have the gym who your mom really likes to workout, the restaurant where you both can enjoy each other meal like a lover, and finally the beach where you and your girlfriend/mom can enjoy the Summer vacation.
