Say nothing

Alyssa turns away from you, locking eyes with Sid again. She starts moving her hips up and down slowly, fucking herself with Sid's cock.

Sid just lies there, saying nothing to you, while Alyssa pleases him with her pussy. Something meant for you, not him, and he knows it.

Alyssa: "Mmmm....I love the feeling your biiiig cock gives me....soooo full..." She says as she brings herself up, revealing a portion of Sid's naked cock, slick with your girlfriend's pussy juices.

Alyssa let's herself fall, her large sweaty breasts meeting Sid's hairy chest. They kiss deeply for a while, until Alyssa starts twerking her butt rapidly up and down on Sid's cock.

Sid: "Uuggghh....yeah.....you're a natural, girl...."

Alyssa: "mmmmnnnn....yeaahhhh" she moans, proud of her ability to have sex with this dirty old homeless man.

Sid has started humping upwards to meet Alyssa's movements, making loud slapping noises. Alyssa is practically screaming at this point, but you suppose it doesn't matter, you're alone now.

You can do nothing but watch the erotic scene unfold before you. Your naked, sweaty, beautiful and big breasted girlfriend is on top of this old disgusting man, with his cock deep in her pussy. You wonder how you got to this point, why is this normal now....

After a while of Sid and Alyssa fucking in front of you, again, Sid rubs Alyssa's sweaty back while she massages his cock with her pussy.

Sid: "I'm coming....soon..."

Alyssa: "Cum in me again...."

Alyssa speeds up her humping, focused on making Sid cum in her pussy. After a little while of them just panting, and rubbing each other. Sid grabs Alyssa's hips and holds her in place.

Sid: "uuuughhhh ...I'm coming....I'm coming in your girlfriend, Matt...."

Alyssa: "mmmmmnnnfff....yeah, cum in my pussy...."

Still, you say nothing, your dick rock hard in your pants. Alyssa sweaty thighs are shaking, orgasming as Sid pumps her full of his cum again. Rope after rope of cum shooting upwards towards her fertile womb.

Alyssa: "ughhh..mmmm...that feels so good...."

Sid: "Cumming in your pussy is like... heaven..." Sid says as he pulls her into another kiss, they join their mouths yet again in the afterthroes of their mutual orgasms.

Alyssa lifts herself off of Sid, his huge cock exiting her pussy with a pop, and slapping his belly. You can't really believe all that meat was inside your girlfriends little pussy.

Alyssa: "ummff...babe, you don't mind if Sid and I take the master bedroom? It's much better to fuck in than the small guest bed. We're going to be fucking a lot, for practice..."

Sid: "Yeah.... practice...."
