Bring her right to the edge of orgasm
From Create Your Own Story
You've already impregnated Valerie twice, and given her how many other loads for free- she'll have to wait for this one.
You slow your thrusting until you're where you started. "Try to hold it in, Val," you whisper to her from behind. Valerie looks back at you, face contorted with mixed pleasure and torture, and takes a shaky breath. Then, she moans, and you fear she's gone already. You stop thrusting altogether.
Valerie tries to push herself against you, but you hold her still. Multiple moans of intense pleasure leave her before she loses momentum, and you start thrusting again at medium pace. The head of your dick is going to explode, but you ignore it, focused on bringing the sister as close as possible to orgasm without actually achieving one. You make one quick thrust, and she cries out in anguish- she's very close now, her vaginal canal is undulating around your dick, begging for release.
You can't let her fall again. Painfully slow now, you slide your cock into and out of her , careful not to pull out completely. Valerie is desperate, trying to reach her clit, to take your whole penis, to finally cum. But it's only been a few minutes; you block her access to herself, and she wails in agony. How long has she been right there, almost about to drown your penis with contortions and nectar?
Can she get any closer? You try making lots of little thrusts, moving in and out only a half inch each way. Your cock tickles her G-spot; her body contorts as she prepares to let go. At this, you stop again, and she remains right there for a few seconds, high squeaks leaving her mouth. She really is trying to keep it in, but you're making it very difficult for her.
You wait as long as possible before slowly rotating her back around, to fuck her on her back. The sensation of your jizz sloshing within her is nearly enough. Her chest heaves with effort as her long, lovely legs wrap around your back. You're basically twitching now, barely moving your dick a centimeter in or out.
"Brandon, please..." Valerie manages, before she has to bite her lip from the strain.
This is it; your dick is done for. She gets it all.
You grab one tit in each hand and slam the remainder of your cock into Valerie's burning pussy; she screams as she finally cums. Your seed gleefully invades her womb once more, filling it to the brim with cum. Valerie's eyes are crossed with the sheer intensity of the orgasm., hair splayed out over the cum- stained floor behind her. Her love sprays from around your shaft, drenching the carpet and spreading the wet spot at least three feet away. Her legs are latched on to you, and you stay balls deep as you fall forward and taste her tongue. As you make out, you grab a fistful of Valerie's hair, now knotted and sticky with earlier sessions' semen.
"Brandon... Fuck... Please..." Valerie manages, between gulps of air and your mouth. Amazingly, she wants more.
Brandon's balls are at full capacity; it's a wonder that they never exploded before you took him over.
You can feel the slight pressure of your own cum, pressing on the head of your dick from within Valerie.
