He should fuck her

Greg could barely form thoughts, with Katie's hand massaging his cock through his pants. Jared paused briefly when Katie asked the question. How far was this going to go?

Greg took a breath. "He should fuck her next. He should stand up and fuck her against the wall."

Jared wasted no time. He stood, undid his pants and slid them to the floor. His boxers followed, and his cock sprang free. Katie leaned into the wall, her chest heaving with every breath. Jared touched her breasts again with one hand, and stroked his cock with the other. He was quick to reach a full erection, and brought the tip of his dick to Katie's pussy. He rubbed her clit with the head of his penis for a moment. For a split second, he was unsure if he was really going to go through with this.

Greg took a little more authority. "I said he should fuck her."

Jared got the message. He grabbed Katie's right leg, and lifted it up, supporting it under the knee. He grabbed hold of his cock again, and aimed it at her wet snatch. He pressed the head toward her slit, and with a single pelvic thrust, jammed his cock all the way in.

Katie gasped and yelped. She didn't realize how big Jared's cock was, and what it would feel like being slammed so forcefully like that. Jared pumped in and out, Katie's body bouncing against the wall. Katie used her right hand to continue squeezing Greg's cock through his pants. Jared grunted as he pounded into Katie's wet pussy. Katie bit her lip to keep from crying out.

"He should fuck her harder than that."

Jared did what he could to up the ante. He used his right hand to grab Katie's hair, which he pulled almost violently. Katie moved in sync with Jared's efforts, and although there was definitely a sensation of mild pain, she found pleasure in it. Jared hammered his hips toward her, each thrust feeling as if it was going deeper than the last.

Katie, when her hair was pulled, intensified her grip on Greg's cock. Once she got more control of her body again, she undid his belt, his pants, and his zipper (one-handed!), reached into his briefs, and pulled his cock out. She licked her palm, and then began jerking Greg's dick.

"He's fucking me now. His cock is deep inside me, and he's fucking me." Katie's breathing was heavy. "What else does the scene need?"
