We'll Help You Get Off if You Stop Watching Porn! Deal?

Our stepbrother won't stop watching porn! It's so annoying. Ever since he broke up with his girlfriend, he has been jerking off all day, every day, and we can't take it anymore. We can't even sleep with all those moans coming from his room, and we are turned on all the time! We have to do something about it. If he's that horny, maybe we can make a deal. We might stop watching those videos if we give him the real thing. Helping him get off seems a low price to pay for some silence, and our pussies are already wet, so... we all win? Especially if his cock is as big as we think it is.
