I need time, all this pain is preventing me from getting hard.

You try to buy some time saying that all that pain is preventing you from getting hard, and propose her to lick her pussy. She just replies with "Too bad, i'm too horny, and want a dick inside of me, Mike, come on and fuck me" You just realized what is going to append and the world around you is now going in slow motion, Mike pushes you aside and immediately pushes his glans on the entrance of her pussy, you can't belive it, you obviosly took a lot more damage than Mike and now he is taking the prize. She starts to moan and you try to touch yourself to get an erection she pushes him away and at the same time you menage to get erect, she unlocks his shock collar while sucking his dick. You think that it's now or never, she lays on her back and you try to show her you erect cock. She looks at you "Mike is younger than you but has a bigger dick, you would be useless if you didn't have these" she says touching your balls. Mike starts to fuck her again and she starts to squeeze your balls, she doesn't have much **** because she is really enjoying Mike's dick. You can feel your brother movement trough your sister hand, you could have been the one fucking your sister. Mike is now cumming inside of her, you try to say something on the lines of -don't make him cum inside of you- but she doesn't care at all. She seems satisfied and Mikes pulls out his dick exposing an enormous creampie. "Do you still want me?" She asks
