"Lisa, don't make me beg, I swear."

Lisa leaned into Gwen again and spanked her again, harder, right where the thigh and butt cheek meet, Gwen's ass bouncing. She felt like she would break Gwen, but knew that she was more than fit enough to go further.

Gwen spread her legs a bit further, taking the full dildo again with ease. Lisa watched Gwen's pussy as the shaft disappeared inside her. She grabbed the dildo again and held Gwen's hip, giving her another good smack on the ass, watching the toned muscle jerk a little in reaction.

"This is…definitely a kink I had no idea I had." Gwen said, looking back at Lisa.

Lisa slid her hand up to Gwen's stomach, then to her tits. She pressed down on Gwen's back, pinning her to the bed, her hand over one of Gwen's tits. She was pressing as hard as she could, exerting as much force on Gwen as she had in her. It was raw and animalistic, but it was utterly perfect.

Gwen took a sharp breath and let it out, "Fuck, Lisa, harder, faster, don't you fucking hold anything back. Don't you fucking dare." Gwen's back was slick with sweat, her entire body begging and hungry for the pleasure only Lisa could give her.

Lisa pushed harder, pushing into the base of the dildo with the inside of her leg as she did her best to go faster. It was an awkward position to try and go hard from, but the slight diagonal angle of it seemed to work well, as Gwen's moans got louder and more sharp.

"Don't fucking stop, keep fucking going, Lisa…"

Lisa fucked Gwen as fast as she could, her legs starting to get weak from the position she was in, her hands getting slippery on Gwen's sweat-soaked skin. She pressed her thumbs into Gwen's ass, making sure her short nails dug in as hard as they could.

Gwen grabbed her pillow and hugged it close to her body, "oh fuck, I'm close, Lisa, god I'm so close…"

"Do you want to get fucked in this position, or do you want to roll over and have me--"

"--no…don't change, fuck me just like this, smack my…fucking ass and make me come, Lisa." Gwen begged.

Lisa didn't respond, instead just redoubling her efforts to fuck Gwen harder, faster. Lisa pulled Gwen up, holding her against her body as she pounded the strap-on into Gwen, feeling every twitch, every breath, and every shiver. She wrapped one arm around Gwen's hips, pulling her as close as she could, and delivered a smack to the back of Gwen's thigh, and then dragged her nails across the red skin.

"Oh god…fucking yes, yes, fuck me like this, please…"
