BIO 3

You can feel it coming. The final breath. The final flash of white. The final gasp of air.

You tap three times on Twilight's leg with the last strength you can muster. The safety signal.

Twilight squeals and clenches around your cock as she releases the hold on your heart and switches back to the walnut in your butt, squishing and pressing it like a diamond under the earth's natural compression.

A sharp jolt the size of your entire body makes your hips jerk up and hold in the air. Twilight's bouncing and bobbing on your cock as she squirts mare-cum everywhere, and your hips keep her held up in that make-shift yoga position as your balls begin to squeeze every last drop of cum out from your insides and then some. If you have pipes, they're not only clean, but pressure-washed, shot through with a thousand reservoirs' worth of water in a hole the size of a peanut. Your dick feels like it's going to explode because of the velocity and viscosity of the semen surging up your shaft and exploding into Twilight's pussy. It's so thick, so creamy, it drips down your dick looking like melted ice cream, mixing with the purple of Twilight's fur and pooling underneath her cunt on your stomach and balls. Your balls, which are still tight, seizing, refusing to let go as long as Twilight keeps her hold on your prostate and squeezes it relentlessly.

Three more taps, and she lets go of that too. Your body feels like it's been built up out of Lego, broken apart, and then repaired with scotch tape. You have to limply bat at Twilight's shoulder with your other hand a few times before she comes down and opens her eyes, then picks herself up your cock and lays down beside you. Your cock is still so hard you could cut glass with it, but even the idea of touching it makes your body seize with over-stimulation. You don't even let it touch the blanket, and lay down on your back, making sure to keep Twilight's hooves away from your member as she lays them over your chest.

The glow on Twilight's horn finally subsides, and with one last sparkle, she flicks the bedroom light off, bathing the two of you in darkness and the smell of each other's sex.

"We have to do that again," Twilight says.

"Thank goodness for safety signals," you say.

Twilight nods.

"You said it," she says, and kisses you.

GOOD END
