Watch them fuck, of course!

I don't touch myself, I don't want to cum that quickly, but my cock still twitches as I watch our bull powerfully pounding my girlfriend's pussy.

After some minutes, they change position. Marie is firm, and moves Monica's body to her will, spreading her legs or squeezing her thighs. Monica just surrenders to her control, and it's absolutely clear she's in no pain, but in total blissful pleasure. She cums again while Marie is fucking her on her side. Her hips tremble as her pussy leaks her juices while her lover buries deep inside.

"You really last long!" I observe, as Marie positions Monica again.

"Yeah, your girlfriend does too! I mean, other girls are tired after one or two hours! Haha! But she's so cute and... Delicious! I'm getting close!"

"I wanna feel your cock pumping inside her."

Marie makes it so Monica is spreading her legs again. Her panties are totally wet. I see how that huge cock comes out of her almost entirely, those 8 ½ inches look even longer, and her girth looks even bigger now! An instant later, all that monster disappears deep into my cute girlfriend's pussy. She's hammering her mercilessly, and Monica's loving it!

"Here it comes, Mon! I'm gonna fill you with my seed!"

"Yes, please!! I love your cum!! Cum deep inside me!" Monica begs lustfully.

I reach between them and grab Marie's cock. She slows down a tiny bit so I can touch her. I wrap my fingers around her shaft and feel it throb and pulse. I love it! I love feeling it pump shot after shot of thick cum inside my girlfriend! And her orgasm is so long! She really cums buckets!

When Marie is done, she slowly pulls out. Her cock is glistening, covered in semen and pussy juices. Monica's pussy starts leaking thick jizz.

"Why don't you clean us up, Julie?" Marie suggests, and I love the idea.

I lean and start licking Marie's cock. It's still hard, although not as much as before. It's so hot and sticky, and her semen mixed with my girlfriend's juices makes for a wonderful treat. Once I've licked it clean and it's only covered with a layer of my saliva, I go to Monica and start eating her. I lick and kiss her labia, and I slurp on more of Marie's cum. It's so much! I wonder how Monica can hold it all inside! I stop after a while, because I want her to keep some of the semen inside still, then I move aside.

After a few minutes of recovery, Marie nods at Monica, who reaches for her shaft and strokes it to full erection again. Then they do it doggy style. Monica curves her back and lifts her ass like a total professional porn star. It baffles me so much, as she's always seemed so adorable and innocent. But of course it turns me on even more. I watch her get pounded for long. Marie holds her hips with such strength, and thrusts in and out with such ****, Monica can't stop moaning, until she cums once more.

"I... I want to feel both of you..." Monica sighs with a begging tone. "Please, I need the two of you too fuck me..."

"Of course, babe"

Marie smiles at me.

"What hole do you want, Julie?"
