It's your grandmother.

"Oh My God! Grandma, y...you're here." you shocked as you're panic. "W...what are you doing here, grandma?"

"Well, I came to visit of course, what's else am I here?" your grandmother replies. "Plus, I've been staying outside for about couple minutes, what are you doing in the house?"

"Sorry about that, grandma. I was just helping my mom to do some housework like cleaning the house, washing the dishes, and do the laundries." you answered as you're made up.

"I see, so that why it took you long enough to open the door, anyway. Can I come in?" your grandmother asked as you welcome her. "Geez, I can't believe it that this house is so clean, you guys must be prepare really 'soon'."

"Sorry, m...mom. We were heard that you'll come here so we decided to do the choir as quickly as possible." your 'mom' walks out in the livingroom as she greet your grandmother.

"Oh my goodness, dear. You're here, and where's your husband? I thought you both were go on the honeymoon." your grandmother asked.

"Well,... uh... y...you see it's kinda embarrassing, mom." your 'mom' spoke as she's trying to made something up, you just hope your former/transformed/shapeshifting girlfriend didn't mess it up. "When we were about to have our vacation, his company was called him and he just cancelled our trip, and that's why I have to stay home with my sweet baby boy."

"Aww, poor girl. I can see why your husband is such a hardworking guy, at least you have your son who is with you." your grandmother replies as you both relieve. "Anyway, I just hope you don't mind if I could stay in about a week, and can you show me where should I be sleep in?"

"Umm... I think you should stay at my parents' bedroom, grandma. I just hope it's easy for you to sleep, right 'mom'?" you asked as you walk next to your 'mom' and asked her.

"Of course, my babyboy. C'mon, mom let help you go to my bedroom." your shapeshifting girlfriend said as she helps your grandmother leans to your parents bedroom. After a couple seconds later, your girlfriend in your mom's body returning to you as she tell you to be quiet your grandmother is sleeping, can't blame her she's old and tired, and she came all this far to visit you. "I guess we're finally solve the problem, 'mom'." you spoke to her quietly. "I just hope she'll begone for early."

"Yeah, I know, honey." your false mom replied then begin to hug you. "Beside, I don't want anybody to disturb us while we have some romantic **** between the mom and her son."

With that, you and her continue kissing passionately while your grandmother still fall as sleep, you just glad that there no one around while you both make love.
