Robin gives a yoga sex class to the ladies

Robin notices that everyone in the gym is naked. Robin stares at the tits of two women using the treadmills. Their tits bounce with each step they do. Those women noticed Robin's beautiful cock and stared at it lustfully, one of them is even drooling a bit.

Robin, Elizabeth, Michelle and Christine enter the room used for yoga and wait for the instructor to show up. Robin stares at the other five women present in the room. They're in the age range 30-45 and they're decently beautiful. All the women present are staring at Robin's cock, some are blushing and only look at it from time to time while others stare at it shamelessly. A few minutes later the instructor shows up. She's a hot brunette in her late forties, she has a slightly muscular body, nice D cups tits and a curvy and beautiful ass.

"Oh! a new face. I'm Jessica, the yoga instructor." Jessica introduced herself to Robin. Jessica also stares at Robin's cock but tries to keeps a professional look.

"Pleased to meet you too, I'm Robin." Robin introduced herself to Jessica.

"Ladies, do some stretches while I teach Robin some poses." Jessica said to the rest of the women present.

"There's no need for that, I learn by watching, not to mention that All of you want to have a sex yoga class rather than a normal yoga class whenever a futanari shows up." Robin said to the instructor and the rest of the students.

"You're right, we want to have a sex yoga class." Everyone said to Robin. "Can you also explain me what is a sex yoga class?" Jessica asked to Robin slightly ashamed about not knowing what a sex yoga class is.

"Of course. It's very simple, women do some poses and the futanari insert their cock inside the pussies of the women. I if possible I would like that you do poses that let me insert my cock easily in your pussies" Robin explained.

"I understood, thanks for explaining it clearly." Jessica said to Robin. "Everyone, get on the wide legged forward bend pose." Jessica said to the other women. Everyone gets in that pose eagerly, wanting desperately to be fucked by Robin.

"I'm gonna start with you, Jessica." Robin said to Jessica and she inserted her cock slowly into Jessica's wet pussy. Jessica moans loudly from pleasure when Robin's cock touches the entrance to her womb. Robin let her rest a few second before she starts thrusting her cock at a pace of 72 thrusts per minute. Jessica's moans fills the room and the rest of the women are getting hornier and hornier with every thrust of Robin's cock. Robin starts spanking Jessica's incredible ass with a moderate strength.

"Hey! What are you doing!?" Jessica shouted at Robin.

"Relax, Spanking is an essential part of the sex yoga." Robin said to Jessica.

"Oh! You're right, forgive me for shouting at you." Jessica apologized.

"Don't worry about it." Robin said to Jessica and kept spanking Jessica's with the same strength as before. A few minutes later Robin releases a huge load of cum inside Jessica's pussy. Jessica's ass was slightly red after so many spanks. "Jessica clearly liked to be spanked, her pussy got tighter every time I spanked her." Robin thought.

Robin decides to fuck Elizabeth, Michelle and Christine after she fucks the rest of the women. After half an hour of intense sex she creampies all of the women except those three.
