Isaac returns

Suddenly the door bursts open and Isaac shouts, "STOP Randy! Get off of her!"

Randy barely paused when Isaac interrupted. Gwen jumped up and screamed at Isaac to get out as she rushed at him. Isaac was startled at seeing his sister in all her naked glory and was surprised by her reaction. So surprised that he backed out into the hallway and she slammed and locked the door. Gwen turned around and told Randy to keep going. "That son-of-a-bitch was involved in this prank too! We'll get our **** on him after we finish with this skank!"

Meanwhile Isaac was pounding on the door and demanding they release "his girlfriend."

Gwen laughed and yelled at Isaac, "We'll release her after Randy releases his swimmers in her fertile womb."

Isaac yelled, "NO! You can't do that! She'll get pregnant!"

Again Gwen laughed, "That's kinda the point, bro. This will teach you and John not to pull pranks on me anymore. You guys can deal with her being preggo!"

Isaac thinks, 'She knows that's John and she's going to let her loser boyfriend knock him up and trap him as a girl forever?'

Isaac renews his pounding on the door as he can hear Randy's grunting and groaning getting louder and realizes that he must be close. Isaac knows he has to stop this now or he is going to lose his little brother forever. He begins slamming his shoulder into the door, **** to save you. He hears Randy shout, "Arrrghh! I'm cumming!" just as the door opens and he falls into the room. He looks up from the floor to see Gwen smirking down at him. Isaac then rolls over and jumps to his feet only to see Randy fall down beside you and your belly, tits, crotch, and thighs covered in gobs of cum.

Isaac looks towards Gwen and asks, "Did he...? Did he, uh, you know, uh, inside her? Did he?"

Gwen laughed at Isaac and crawled over to the bed and began scooping up the gobs of cum from your belly, while licking and sucking the cum from your tits. She then takes the cum in her hand and holds it over your open mouth. She turns her hand and lets the cum drip into your mouth. You taste the salty and slightly sweet taste of the thick fluid before it slides down your throat. As you swallow the cum, Gwen is moving down your body, kissing and sucking your tits and belly, cleaning the rest of the cum from your body. She straddles your face and lowers her pussy onto your mouth as she licks the fresh cum from your thighs. Suddenly you feel her mouth on your sensitive pussy as her tongue invades your well used cunt.

While all of this is happening, Isaac is standing there with his mouth agape. He can't take his eyes off of the scene of his sister kissing and sucking his brother turned "girlfriend." When he sees Gwen licking and sucking up the cum from your belly and thighs and then licking your cunt he suddenly worries that Gwen may push the cum inside you and lock your transformation. Just as he is having these thoughts he hears you moan and looks to see you are actively licking Gwen's cunt. He feels his pants tight in the crotch area as his cock is seemingly trying to rip through the fabric. Isaac reaches down, unzips his pants and lets them drop to the floor. He then takes his hard cock into his hand and begins to stroke it as he continues to watch you and Gwen. Unknowingly he has moved closer to the bed so that his cock is mere inches from Gwen's head. Gwen looks up and sees Isaac's cock right in her face. Lost in her lust she doesn't even think about who's cock it was. She just started kissing and sucking the cock head into her mouth. She wrapped her lips further up the cock and grabbed Isaac around the waist to pull him onto the bed and between your legs. Using her mouth and her hands, she guides Isaac's bare cock to your hot, wet cunt. She lines the cock up with your cunt and moves out of the way. Isaac sighs as he pushes forward and sinks his big cock all the way inside you. Isaac pauses with his cock fully inside you and his balls resting against your ass. He looks down at you as he pulls out until just the tip is inside. Again he pauses for a brief moment, looks into your eyes. You slightly nod. He smiles and pushes back inside you. He starts to slowly stroke himself in and out of you as he reaches up and unhooks the gag in your mouth. As soon as the gag is removed you smile at him as he continues to pump himself in and out. "Oh Isaac," you say between gasps. "I thought he was going to trap me forever. But you came back and saved me."

Isaac smiled down at you as he picked up his pace. You felt his swollen balls slapping your ass on each stroke as Isaac began to pant and grunt. You feel your arousal rising again as Isaac slams his cock in and out of you. You can feel yourself getting close to another powerful orgasm. Looking into Isaac's face you can tell he is concentrating to try to last. He is trying to hold back his orgasm. 'His orgasm? With his uncovered cock inside you? Oh No!'

"Isaac! Oh Isaac! OH GOD! ISAAC! You're not safe! No OOOHH! No Condom! You... not... wear... condom... I.... get.... pregnant!"

"YES! I'm going to cum inside that sweet cunt of yours and knock you up!" he shouts.

Meanwhile, Gwen has been licking, kissing and sucking Randy's cock back to his full hardness and he is ready to blow. Gwen pulls Randy's cock out of her mouth and squeezes his balls while he strokes his cock and shoots another massive load all over your face and tits.

Feeling the hot cum hit your face and tits while being pounded by a thick, hard cock triggers your orgasm, causing your cunt to squeeze and milk Isaac's cock. Your cunt massaging his cock and seeing you getting covered in cum is too much for Isaac and he can't hold back anymore.
