"Hey, honey. Why don't take a shower with each other, it's not good to get dirty, y'know?" your shapeshifting girlfriend asked.
"Okay, babe. Let's us go." you answered.
"Oh and by the way, when I'm wearing or looking like your mother, just referring to me as 'Mom', okay sweetie?"
"Whatever you say, 'mom'." you answered you both leans each other and kisses passionately. And one minutes later, you both headed to your bathroom, you and your 'mom' (also know as your former/transformed/shapeshifting girlfriend) continue kissing and hugging so tight with each other and then move to the shower. Once you both in the shower, you and her broke the kiss and turn on the shower to warm water. With that, you and your 'mom' wash and each other in the shower, then you leans down to her breasts taking one in your mouth and the other in your hand. As you sucked and squeezed, you could hear the soft moans coming from your fake mother, and this only turned you on more. While you continue sucking her breast, you reach your hand down to your mother's crotch to find that she was very wet. "Wow, I didn't know you were wet down there, 'mom'. You must be horny because of me." you smiles at her.
"Well, maybe it's because of the shower rain." your 'mom' (who still your girlfriend) smiles as you back. "Let me turn around and why don't put your 'little friend' between my legs so I could give you a thigh-job, sweetie."
When she finish her sentence, your 'mom' turn around and you step behind her back as you're putting your cock between her legs that she told you to. Once it attach, you move your hips back and forth, back and forth as you both moans. During you're doing a thigh-job, you then grab her breasts and fondle them. "Oh god, you're such a horndog, sweetie." she said as turn her head to you and holding your face with her hand.
"Hehe, I guess you're right, 'mom'." you replies as you kiss her. And then, neither of you two can take it anymore, you both release the seeds at the same time, and you pull out your cock and you spray on her ass. Once finished, you stand there feeling great that your semen is all over her ass. However, it wasn't too long before your 'mom' take your semen and lick it. "Mmmmmm, now that's what 'mommy' needs. You taste better than ever sweetie, but it's not over yet." your 'mother' said.
"I know what are you trying to say, 'mom'." you replies back to her. Then you holds your 'mom' as you put your dick into her pussy. Both of you gasp at the feeling, as you are now completely inside your mom once more, now you both are having a standing missionary sex.
"Oh yeah, oh yeah, that's it, sweety. Please make your 'mother' feels good, make love with your 'mommy' like you usually do." she's said in her soft moans. After settling a little, you then move up and down rhythmically like you did the thigh-job. A few moment later, your 'mother' finally hits the spot and forces you deep inside of her where you finally explode. You hold her tightly against you and kiss her gently as you continue to release your seed deep within your 'mom'. Both of you exhausted, but you and your 'mom' still like to enjoy having sex with each other in the bathroom shower. After that, you both came out of the shower and take some towels to clean each other. "Achoo, geez. I can't believe that we've been too long in the shower, sweety." your 'mom' said as she's sneezing and you can see that's she almost turns herself back to your original shapeshifting girlfriend. "But still I love how we enjoy our sex."
"I know, right." You replied.
"BTW, now that we finally got some shower, what do think we should do next, sweetie?" your 'mom' (shapeshifting girlfriend) asked you as you're thinking.
