"Now, for your transform, you will change into anyone while we have sex with each other, both physically and mentally." you answered.
"Oh my, that's really kinky and erotic, hun. But I like it." Your girlfriend surprises and smiles when she heard your answer. "And by the way, I've never known you would think about sex when we play a game."
"I know, babe. I know." you said as you're scratching your head. "But to be honest, I've been thinking about my cock as I had to get this idea, babe."
"Well, I don't blame you, hun. I know you boys can stop thinking about sex." your girlfriend replies when she's crawling to you. "Besides, I'm also feel so horny when you're not around, I've been masturbated a lot and think about you a lot, so when you're saying this. That turns me on."
When she finished her sentence, she starts to kiss you deeply and passionately. Soon, you let go of your kiss and began to strip off all of your clothes until you both naked, before going back to kissing. Then you both stopped and looked to each other bodies in naked and were ready to take it to the next level. Your girlfriend take a look to your hard cock which was tend high, ready for some action.
“My…” she said with lust in her voice, “Looks like someone is ready for me.” with that she was about ready to put your cock into her vagina. Once it's ready, she leans back onto your cock taking the whole thing in as both of you gasp at the feeling. After settling a little, she begins to move up and down rhythmically. Soon after this she speeds up more, bringing you to move your hips with her. As your both start to feel a building feeling, you sit up and grab her hips making her go even faster. While, you both continue thrusting, your girlfriend's body starts to feel tingling as she's transforming if you have sex with her.
