But ofcourse, they're best friends

Chris opens his mouth and Rob takes it as an invite to thrust right in. Since they've been doing this since Chris was 16, Rob has no problem to go in balls deep as he pushes Chris making him use his arms to hold his head up to make it more easier for Rob to go in balls deep and less painful on Chris's side. Rob puts his hands on the back of Chris's head and starts face fucking him fast and hard.

"Your mouth always feels good. Especially when you involuntary start to swallow." Says Rob as he takes his hands off of Chris's head leans over Chris and pulls down his jeans showing off his ass. Shortening the amount he pulls back before thrusting back in and leaving it in his throat for awhile, wile still letting Chris get enough time to breathe. "No fair you let that guy fuck you before you let me." Rob starts to spread Chris's cheeks apart. "Yep, he tore into this hard. It's all red and swollen." Rob wets one of his fingers and pushes it in and wiggles it around making Chris pop up his ass a bit. " He must of poured in a lot. It's still all wet in here. Yet it's still tight. Maybe you want some more in there?" Rob says as he starts to finger fuck Chris while fucking his face. "How about you let me in here day after tomorrow?" He starts to finger fuck him faster and harder, and fuck mutters a bit in pain. "Say yes and I'll stop. Or not and I'll just have some fun back here and let Lexi see you all submissive." He says while another finger starts poking around his hole.
"Mmmmmm... Mmm. Gggggaa." Chris says while Rob still has his dick balls deep down his throat.
"What was that?" Rob says as he pulls his dick out of Chris's throat and forces another finger to go far up his ass.
"Yeggg!" Chris says somewhat mutter as Rob thrusts his dick back down his throat.
"Good boy." Rob says as he takes his fingers out of Chris's ass and pulls his jeans back up. "Lets keep this ass away from Lexi eyes. She might want to play with it too, and I want that to be a us thing only."

Rob starts to fuck him faster as he is about to cum. Leona walks in as Rob makes some final thrust down Chris's throat and grab his head while cumming.

"Ahhh." Rob says with one eye open. "Keep swallowing like that. Feels good and makes me want to cum more. Milk it!" Rob says while forcing Chris's head into his pubes.
"Hot." Lexi says.

Rob pulls out and leaves his dick in front of Chris's face still erect for Chris to clean up. Chris just licks up and down the base and swirls the head in his mouth then plops back down.

"Aw, you didn't pull out and cum on his face." Lexi sighs.
"It was feeling to good in there, I didn't want to leave it. But I let a little ooze leak out so you can see him clean it." Rob says while zipping back up.
"Least I came back in time. Had fun Chris?" Lexi says.
"Meh! Throat hurts now." Chris says.
"Heh. But it was worth it, and I enjoyed it. Missed your mouth." Rob says.

The three had fun talking, eating, watching tv and playing game. When it got too late. Lexi left and Rob followed behind her after giving Chris a slap on the ass. When they left Chris got undress and felled asleep in bed, he could of sworn her her the door open and close three times. But he was to tired to care much, being **** twice a day does that too him.
