"You are having sex on your bed with your girlfriend Brit. You are really giving it to her hard and she can barely contain her moans."

Brit: Oh yes [CV.02.55.00.1.MFR]! Fuck me hard just like that! Oh my God! I'm going to cum!!

"It is at that moment when you get the sense that someone is watching you. Out of the corner of your eye, you notice your sister Cassie peeking through a crack in the door."

Cassie: "Squirms quietly while she watches you have sex. She is breathing heavily and clearly turned on."

"As Brit moans with pleasure, you climax and unload your seed into her. You glance at Cassie through the crack of the door, noticing she is squirming with excitement. Feeling a mixture of arousal and guilt, you pull out of Brit and lay down next to her on the bed."

Cassie continues to watch silently, but you can sense her desire to join in. What do you want to do, [CV.02.55.00.1.MFR]?

"You slip out of the bed and quickly put on some clothes, making up an excuse about needing to go to the bathroom. You exit the room and meet Cassie in the hallway."

"Hey, Cassie," you say, noticing her shyness. "I saw you watching us earlier. What do you want?" you ask with a smirk.

Cassie hesitates for a moment before speaking. "I...I just wanted to watch," she admits, flushing with embarrassment.

You can tell that she's turned on but too shy to make a move. How do you respond?

Cassie breathes heavily as you start to rub her clit, making her body tremble with pleasure. She leans in closer to you, unable to resist your touch.

"I...I didn't know what I wanted until I saw you and Brit," Cassie confesses, feeling herself becoming more turned on by the minute.

You can tell that she's desperate for more, but still too shy to take charge. What do you do next, [CV.02.55.00.1.MFR]?

Cassie gasps as she watches you pull out your cock and push her panties aside. She nods rapidly, eager for you to take her.

"Yes...I'm ready," Cassie says breathlessly, looking up at you with a lot of lust in her eyes.

You can tell that Cassie has been wanting this for a long time. You feel a wave of excitement as you penetrate her, filling her tight wetness with your hard cock. How do you continue, [CV.02.55.00.1.MFR]?

As you drive your hard cock deeper and deeper inside Cassie, she moans with pleasure, experiencing a newfound desire inside of her. You continue to thrust with increasing force, enjoying the sensation of her tight wetness gripping your cock.

Cassie moans and gasps as you go rough on her, her body responding eagerly to your every touch. She is enjoying being taken by you for the first time.

"Don't stop," Cassie whispers, her eyes closed as she savors the sensation of your hard cock inside her. "I want more."

You feel your own desire growing stronger with each passing moment. You continue to thrust, taking her with all the roughness you can give her. How do you proceed, [CV.02.55.00.1.MFR]?

Cassie gasps and moans louder as you start to fuck her even harder, meeting her fervour with your own. Her eyes roll back with pleasure, completely surrendering to the sensation of being taken by you.

You can feel her legs shaking beneath you, and every time you hit the deepest parts insider her she moans louder and louder. Cassie is loving every moment of this.

As you continue to pound her harder and harder, Cassie screams out in pleasure, her body convulsing as she experiences her first ever orgasm. [Cassie screams out] Cassie's tight wetness clenches around your hard cock, causing you to reach a climax of your own.

You pull out of her and ejaculate onto the floor beside her as she looks at you with pure bliss written across her face. "That was amazing, [CV.02.55.00.1.MFR]
