[M4F] Mistaken Identity!

Hey there! I’ve seen prompts in the past similar to this and I’ve always wanted to make my own and finally gotten around to putting pen (or keyboard?) to paper!

This idea revolves around my girlfriend/wife having a twin sister (your character) who is a lesbian. Through a series of unfortunate events or mix ups, I one day I end up fucking you thinking I’m actually having sex with your sister/my girlfriend. This can end up happening in a few different ways, one of which I have included in the starter below, but we can get a bit creative with it since your character will be an identical twin it doesn’t rely on my character not seeing your face! Perhaps my girlfriend likes to roleplay as you when we are in bed so that is why I don’t realise it is actually you!

Naturally your character would enjoy the experience more than she expected, which is why she doesn’t push me off and instead leans into it. As you might have guessed, themes of ‘lesbian turns straight’ are definitely appealing to me and so I’d love to include those in here. If you would prefer to dial up this aspect, and dial down the cheating aspect of this roleplay, we can also do that instead. Perhaps your sister is my best friend or coworker who I think I am having a drunken night with or my roommate and I have a freeuse arrangement and I don’t realise you have come over for the day.

I’d prefer this to be a long term roleplay so we can do multiple scenes. My character realising what has happened during or afterwards but continuing to have sex with you or perhaps I don’t realise and your character keeps putting herself into situations that allow me to think I’m using your sister. I would love to hear your ideas on any aspect of this prompt!

For the more technical stuff, my kinks are incest, oral, anal, sexy outfits/lingerie,breeding and petplay. Limits are most extreme stuff, gore, non-con, heavy bondage, toilet stuff. Just don't send me the start of a roleplay as I prefer to talk things over first and when we do get started. I also prefer to control my own character rather than have my partner perform some of my actions.

Below is a starter to inspire you though we don’t have to use this exact one!

We had decided to go on a trip with our friends to a nice beach resort to rest, relax and generally get away from the stresses of day to day life. My girlfriend is very close with her twin sister so we invited you along as well, even inviting your girlfriend if she wanted to come. We had rented out a beachside house to serve as our hub for activities.

On this particular afternoon, a few of us head out for a dip in the ocean while our girlfriends go shopping and a few remain at the house relaxing, including you. By the time my group returns later in the evening, I’m unaware that my girlfriend’s group has decided to do an impromptu bar crawl while of those in the house have gone to bed. I dry off and head to the room we share with you, mistaking you for my sister who I think has already come back and to bed before me. I quietly climb into the bed as best I can and wrap my arms around your waist, pulling you close, “Hey, did you miss me?” I whisper in your ear, kissing your neck gently as my member hardens and rises between against your rear.

If this sounds fun to you then I’d love to hear from you! Thanks for reading!
