Late the next morning, Gwen entered the apartment carrying a grocery bag and found Peter hanging from the ceiling naked.

"I missed you." He greeted her.

"Awww, how sweet." She said half-jokingly. "What's up?"

"The safe word is 'Stop'." Peter replied. "It starts when you say you understand."

Gwen blinked from surprise. "Oh. I was thinking we would do this tonight."

Peter shrugged. "We can wait until tonight if you don't wanna do it now."

Gwen bit her lip. "Fuck it. Let's do it now."

Peter smiled. "Cool. Say the words."

Gwen took a deep breath. "You bet your ass I understand."

"Good." Peter licked his lips. "Come on up."

Gwen nodded and crawled up the wall to the ceiling, then started crawling towards Peter.

"Wait." Peter said.

Gwen stopped. "Yes?"

Peter smiled mischievously. "Take off your shirt."

Gwen blushed a little as she removed her shirt and let it fall the floor, revealing a lacy black bra.

"Good." Peter said. "Now your shorts."

Gwen turned a brighter shade of red as she took off her shorts, revealing lacy black panties that matched her bra.

Peter grinned widely. "You were expecting this."

Gwen shook her head. "Just wearing them all day so I was ready."

Peter's cock got harder. "Come here. Let me see."

Gwen felt her arousal grow as she crawled closer to Peter. "Do you like them baby?" She asked innocently as she perched on the ceiling right in front of Peter.

Peter bit his lip and cupped Gwen's breasts through her bra. "I love them." He said, giving her breasts a firm squeeze.

"Mmm…" Gwen gasped. "I hoped you would."

"I do." Peter replied. "But I'd love them even more if you took them off."

"Yeah?" Gwen bit her lip as she unhooked her bra and let it fall to the floor. "How's that?"

"Better, but slow." Peter said. "Do it faster."

"Yes sir." Gwen slipped off her panties and dropped them.

Peter blushed lightly and broke character. "You don't have to call me sir."

Gwen chuckled nervously. "Yeah, this isn't doing much for me. You?"

Peter shook his head. "Not really."

Gwen got a big smile on her face. "I got it." She said, crawling past Peter to the wall. "Fuck me upside down." She straightened her legs so she was standing upside down with her back to the wall.

Peter got visibly harder. "Damn I want to, but how are you gonna hold onto me?"

Gwen giggled. "You'll see. Get over here and fuck me."

"Oh baby." Straightening his legs, Peter walked across the ceiling to Gwen, who wrapped her arms around his torso under his arms.

"I'm gonna jump, ready?" Gwen asked.

Peter grabbed her hips and nodded. "I got you."

Gwen lifted her legs down off the ceiling and wrapped then around Peter's waist. Peter leaned into her, pressing her up against the wall so her weight was held up by both him and the wall.

"Ready?" Peter whispered.

Gwen nodded. "I fingered myself to this exact scenario a month and a half before I told you I love you. You're damn right I'm ready."

That drove Peter over the edge, and he pushed into Gwen and started fucking her.

"Oh shit!" Gwen moaned, clinging to Peter as he thrust into her. "Give it to me Peter!"

"Oh baby!" Peter moaned. "Anchor me so if we fall it's not on our heads!"

Understanding, Gwen fired four webs at the ceiling and attached them to Peter's back, leaving enough slack for movement. Peter smacked the side of Gwen's ass and started fucking her hard.

"Oh my god!" Gwen gasped loudly. "Peter!"

"You like that don't you?" Peter moaned in her ear, nipping at her earlobe.

"I fucking love it!" Gwen whimpered. "I'm close baby!"

"Cum with me!" Peter groaned.

"PETER!" Gwen screamed as she came a moment later.

"GWEN!" Peter shouted as he came with her.

With Gwen still clinging to him, Peter fired webs at the ceiling and swung them down onto the bed.
