Slow down

You slow down as you feel that you can cum anytime now. Jennifer falls into your arms tired but you are ready for the next round.

"Switch!"

Amy stands over Jennifer's shoulder and waits for her to get up. She only has her socks on.
"Girls, what have you planned for the following rounds? Fucking is already covered."
"What do you think I have this lube for?" asks Amy.

Your cock throbs at the thought of what it can mean.

Amy pours out some lube and puts it on your penis. Then she puts in on her finger and slides it up her ass.
"Am I really going to fuck Amy's ass?" you think.
You are. She turns around, sits on your lap and helps your cock to find it's way to her forbidden hole. Amy's anus is tight! But you can't wait any longer. You put it all in.
"Ouch!" she moans. "... keep going John!"

You are going to give her all you have. You impale Amy on your hard cock over and over again, squeezing her asscheeks and spanking her. She is enjoying it.

"Fuck me like your little bitch, John!"

Oh god, Amy, this feels so good. You begin to feel like you are about to cum again.
