Rise to the occasion and give Chris the shaft

Jen looks at you, a little cross. "Now we don't have much time if I'm going to get home before my curfew ends. Either you fuck my boyfriend right now and put a load in his ass, or you have to use your ass or mouth to bring him his well deserved orgasm."

Chris takes his mouth off Jen's pussy. "It's okay..." Chris says.

Jennifer cuts him off. "Shut up Chris!" She looks to you. "What Chris really wants is for you to make him cum. You can see how hard he is, so what's it going to be?"

You look down the length of Chris's back toward Jen. His quick oral attention left you clean and partly hard. Chris's balls are clenched tight against his root, and his dick is pointed out at full erection.

"Chris, bro?" you say. "I gotcha." You grab the lube from beside your bed and slick up your cock, stroking it back hard enough for the job. After two loads in Jen, it was a little work. But having them both. Having Chris and Jen's asses tonight. Your chest thuds with excitement and your cock firms up. "Kneel up, bro." You put your cock on target, tip to Chris's tight butthole with its little wreath of golden hair.

"Like we practiced, now!" Jen prompts Chris.

Chris presses back at you. You feel him open and his ass swallows your cock head.

"Whoa!" you say with surprise. His ring slides along your shaft. "Your ass is fucking eating my cock. Wow."

"Yeah," Chris pants. "Oh yeah."

Chris's ass is hot on your cock.

"Fucking good," you breathe. "Wow."

Jennifer laughs and claps her hands. She smiles broadly at you. "Hurry up, boys, I gotta get home!"

Chris starts thrusting back at you, running the fuck from below.

"Oh yeah, so good," Chris says. "Oh yeah."

"You're so hot," you breathe. "Can I move too?"

"Yeah, take it," Chris says.

You put your hands on his muscular buttocks and start thrusting. Chris breathes hoarsely, moaning with every thrust. Jen's eyes are wide and bright, taking in everything.

Where Jen's ass was so alive and responsive, squeezing your cock as she squealed with pleasure, Chris's ass is better for a good plain fuck. You thrust in and out, harder and faster as he moans in front of you, his wild blond hair damp with sweat.

"Ah. Ah. Ah, gonna come," Chris cries out.

You move faster, trying to catch up, but Chris is way ahead of you.

"Ahhhhhh! Ahhhhh! AHHHHH!" He cries out loud. His ass squeezes rhythmically on your shaft, and his seed lances across the towel on your bed.

"Yeah, yeah, yeah!" Jen cheers. "Get it, get him! Give Chris your load!"

It feels really good, you're hot and hard, fucking away in your friend's ass, but you're not sure you can give Jen what she wants before her curfew.
