The next day, Peter entered the apartment and was immediately pounced by Gwen, who jumped on him and wrapped her arms around his neck and her legs around his waist.

"Gah!" Peter gasped, struggling to keep his balance as Gwen kissed his neck.

"I missed you, if it wasn't obvious." Gwen said, leaving a hickey under Peter's chin.

"I missed you too." Peter replied as he grabbed Gwen's ass, squeezing it as he held her up.

"Take me to our room." Gwen said.

Peter's eyes widened. "You said 'our room.'

"Yes I did." Gwen started grinding on him. "I've also realized something."

"What's that?" Peter asked, a bulge forming in his shorts as he walked into the bedroom.

"We haven't tried doggy style yet." Gwen replied as she leaned back and removed her shirt, revealing her breasts.

Peter thought for a moment as he pulled off his own shirt. "Holy shit you're right." He said, reaching up and started groping his girlfriend's breasts.

"I know!" Gwen gasped as Peter felt her up. "I couldn't believe it at first."

"We both know what this means." Peter tossed Gwen onto the bed.

"You're damn right." Gwen slipped off her shorts, leaving her completely naked. "Say it."

It took Peter a moment to realize what she meant. "Oh." He quickly removed his shorts and underwear. "Get on your hands and knees."

Gwen happily complied, wiggling her ass in the air as Peter climbed onto the bed and kneeled behind her.

"Gwen Stacy, you have the greatest ass in existence." Peter squeezed her ass with both hands for emphasis.

Gwen bit her lip. "Yeah?"

"Yeah." Peter used Gwen's ass to hold her in place as he shoved his cock into her without warning, catching her off-guard.

"AH!" Gwen cried out as her boyfriend fucked her. "Peter!"

"Oh Gwen!" Peter gasped, giving her hair a tug as he rammed into her.

"Spank me baby!" Gwen moaned.

"Gladly." Peter slapped her ass firmly, alternating hands as he fucked her from behind.

"Peter!" Gwen yelped. "Give it to me!"

"Yeah?" Peter groaned. "You like that?"

"Fuck yes!" Gwen whimpered, arching her back. "Harder!"

Unsure if she meant spanking or fucking, Peter did both.

"You know," Peter moaned as he rammed into her harder. "I don't know if you're the sluttiest nerd I know," He spanked her sharply. "Or the nerdiest slut."

"Me neither!" Gwen moaned breathlessly. "But you're definitely the sexiest nerd I know!"

"I guess that makes you the sluttiest nerd." Peter moaned a little louder.

"Only for you!" Gwen replied. "I'm close!"

Peter leaned forward, pressing his chest to Gwen's back. "Is that so?" He nipped at her neck, leaving a mark.

Gwen whimpered and nodded. "Cum in me Peter!"

20 seconds later they cried out and came together. Peter rolled off of Gwen and onto the bed next to her, and Gwen simply rolled onto her back.

"I can't believe that was our first time doing doggy style." Peter panted.

Gwen blushed. "That was my first time doing doggy style, well, ever."

Peter looked at her with wide eyes. "Wait really?"

Gwen bit her lip and nodded. "Yeah."

Peter chuckled. "Huh. Cool."
