Welllllllllllll.....

Your sisters words fall on deaf ears as you suck her cock in stride. Your hand starts rubbing your own clit hard as you feel your pussy go numb from the sensation. You hit that wall again and can't understand why you can't push yourself over the edge. You start to get so frustrated that you begin to think irrationally. Its like you're a bitch in heat and almost rabid with the need to cum. You need to do something about it and fast before you go crazy.

You carefully start to stand with Gwen's cock never leaving your mouth. You mind races with the thought of how harmless it would be to take this monster inside you just for a few moments while trying to shut out the fact you are very much not suppose to do that. You didn't care of the consequences but just knew that it wouldn't take long to scratch that itch. Just to get some relief. Yes all it would take it a few moments. Your sister must have been far from cumming since she just came not to long ago. When you were a guy you always needed to time to recharge after blowing a load as big as that. The experience was enough to convinced yourself you were safe. You grip Gwen at the base of her cock and release your mouth.

Gwen had shut her eyes the whole time and unbeknownst to you had been on the verge of cumming since the shower. She was so sensitive to your touch that she was practically shivering from pleasure. Your hand was sending waves of sensation throughout her body as her new lady balls churned and throbbed. Gwen was confused as to why you took your mouth away, and even more puzzled when she felt you thighs on either side of her. She opens her eyes to see you hovering over her cock rubbing the head against her clit.

“Sarah,,,umm what are you doing.” Gwen gasps as she feels the warm wetness of your pussy drip around her cock.

“I know I know , but I can't take it anymore. Give me 5 …...minnnnnnnutessssss.” You grunt out as you mount your sister before she could protest. Gwen's eyes bulged out as she watched her cock engulfed by your soaking wet cunt for the first time. Your mouth falls open to a silent scream as you body shakes from pleasure. You pussy clamps down hard squeezing Gwen in all the right places. She goes limp as the sensation was overwhelming.

“Oh godd what the fuucccck!?' Gwen forces yells out as her balls start to twitch. .

“I know this is bad..... but I just need... a minute of this and I'll suck you ...oooo off.” You say as you tense up. You feel a mix of pain and pleasure as your pussy adjusts to her massive size. She was deep inside to the hilt as you ass came to a rest on her lap. Every move you made caused the walls of your tight cunt to contract around Gwen's throbbing cock bringing her closer to eruption . You were seeing fire works and just knew that the orgasm with a cock for the first time would be monstrous. You braced yourself on Gwen's shoulders and start to grind your hips, rocking back and forth on her dick. Gwen started to breath heavy. You then start to slightly lift yourself off Gwen and slam yourself back down on her her cock as you being to really fuck.

“Fuck I'm almost there. I think I'm gonna cum....oh shiiit.....”You shut your eyes tight as you are held on the edge was Gwen's cock hitting all the right spots. Little did you know Gwen was on the verge of eruption.

Gwen took a sharp breath in and held it as she was completely taken by the immense sensations. All she could do is throw her head back and grip your ass pushing her cock as deeper inside of you. Her cock was being milked by your pussy as it moved in and out with ease. You slam you body down on her cock one final time taking her to the hilt pushing her against your cervix sending you over the edge.

“Oh fuck I'm gonna cum. Yesssssss” You scream out as you lean back gripping your sisters shoulders. You start moving into overdrive rotating you hips fast. With her dick stuck firmly in place, the wave of ecstasy was far to much making Gwen's balls contract all the way up as she is pushed past the point of no return. Gwen's eyes roll to the back of her head as she exhales hard as her own orgasm hits. Her cum started to boil over racing out through her cock.

As you are riding out the most intense orgasm of your life, you feel a warm tingling sensation spread inside of you that only intensifies your pleasure. Unknown to you it was the first many spurts of cum emptying out from Gwen's balls filling your fertile cunt. Her thick cum pulsed out in jets painting the walls of your tight pussy as you unknowingly milked you sister's cock. All Gwen could do is hold on as she send ropes of her thick potent cum inside of her sisters pussy. Every thrust of your hips sent another thick stream of cum deep inside.

After what seemed like ages and many spurts of cum into your now satisfied pussy your body goes limp. Still riding the high of orgasm you slump your against Gwen's as you both move in and out of consciousness. You start to feel the softening cock inside of you and the rush of fluid start to leak out onto you inner thighs as you both start to doze off.
