Had a free moment, thought I'd get a future installment of SCR queued up

Peter turned to Mary Jane for help. “I just. We’ve got a good thing. Here. Good thing. No one knows about it, so the only way this gets ruined is if we do it to each other…”

She took his hands and put them on her breasts. “Do it to each other?” MJ repeated wonderingly.

There was only so much fortitude a man could possess. With his hands still soaking in Mary Jane’s sweaty tits, Peter pushed her back, then Mary Jane felt a buzz as he adhered to her flesh with Van der Waals force. Sidling one elbow over Felicia, he pulled Mary Jane back to him, sandwiching Felicia against him in the process. He kissed Felicia and he kissed Mary Jane over Felicia’s shoulder. The three of them kissed for the longest time, their tongues in and out of one another’s mouths with a slow, tender grace that lasted right up until the two women moved lower.

“Hey Miss Kitty,” MJ stage-whispered in her friend’s ear. “Mind showing me how to deep-throat?”

“Sure thing, firecrotch. You just put your lips together and blow.”

Felicia stood, running her hand up Mary Jane’s face as she came away from her. Then she circled around Peter, embracing him from behind, her chin on his shoulder. She looked down at Mary Jane as the redhead knelt; MJ tugged Peter’s pants down under his cock and Felicia held his sweatshirt up out of the way.

“He’s got such a big cock, doesn’t he?” Felicia purred, ostensibly to Mary Jane, but her lips were right next to Peter’s ear. “How are you going to take all of it, MJ? How are you going to fit every last inch in your mouth? In your throat? You’re Spider-Man’s girl now, Red. He’s a bona fide hero. My Spider deserves to have each and every bit of his cock sucked. And I can’t be the only one in this relationship that he throats.”

Mary Jane smirked up at the two of them; Felicia seemed almost more eager than Peter for her to suck him off. She knew what Felicia was doing. A little thrill went through her. Just because they were sharing Peter didn’t mean the competition was over. And Mary Jane had a feeling she was going to enjoy the rivalry more than ever.

“First I get him all nice and hard,” Mary Jane whispered, her succulent lips getting closer and closer to Peter’s half-hard member. Peter had an especially high libido and Mary Jane had never known his cock to be reluctant to perform. It had to be a sign of just how much she and Felicia had drained him—literally—in the last twenty-four hours. MJ wondered if in time, his body would adapt to the new demands placed on it, giving him a more active sex drive than ever, or if she and Felicia would have to rely on each other. Both seemed like attractive prospects.
