Alex

Alex pulls out another strap-on, a 5 inch slightly-translucent purple one. She climbs onto the bed, pointing her dildo at you and says, "Suck it bitch."

You start licking by the head, unsure of what else to do. You try to copy what you've seen in porn before but can't quite get it right. Alex notices that you're struggling and calls Katrina over, "Come help our little slut-in-training out Katrina."

She lies down on the bed next to you, smiling softly. "So, a good blowjob always starts with a handjob." She grabs your hand and wraps it around the fake cock, jerking it with you. "You wanna get your man nice and hard first. Then you start licking the head, just to tease them a little." She wraps her lips around the tip of the cock, her tongue slightly out of her mouth licking the shaft. She then pulls up, and pushes your head down onto it. After you've gotten the hang of it, she starts pushing you down further saying, "Good, now you can get started. Bob your head up and down on it, slowly at first until you can take it all. Be sure to look up at your man while you're blowing him... with sexy eyes. They love that."

It felt weird taking blowjob lessons from your crush, but you followed her advice. In no time you were sucking the cock at a decent rate, and had gotten almost all the way down without gagging. Katrina would occasionally pull you off to suck it herself. She grabbed one of your hands and slid it under her bra, then grabbed the other and slid it into her panties. You started to fondle her tit and finger her while you looked to see what your sister was doing. Amanda was sitting in the corner, fucking herself with a vibrator and filming you. You looked back up to Alex as your mouth went back down to her cock. She had a smirk on her face as she recorded her own **** video.

"You're starting to get good at this Marcia, later tonight we'll have some friends come over and give us a second opinion though."
