Nn-nope! He seeds her fields good!
Despite promising to his Sister that he would pull out, He really didn't wanted to do it. She was nicely snugly massaging his flare as her cervix kisses his flat gland with each thrust. He was nearing his limit as he groaned loudly

Your spectral projection divides into two, one that was inside of AJ, seeing the mating from the inside as well seeing from the outside, seeing your current refuge swinging and swaying, smacking against the winking clit of the Apple mare. She moans and groans but perked up feeling the flare inside begins to throbs inside.

Meanwhile, you managed to mantain the bubble spell as the sperms started to get agitated as the tubules' walls pulsed as more of Big Mac's genes swarmed about, the entire chamber was swaying and the sphincter quivers and dilate before an sudden pressure was felt coming.

It was time. The sphincter shut open as you. Along countless sperm cells were shoot out and rejoin with the content of the other testes as you held the shield bubble, passing through the Vas Deferent and onto the prostate on seconds, filling up the sack as it bathed the cells on cowpier fluids and then passed and pumped through another long, pulsing cavern-tube.

You saw through the outside spectral projection as Bic Mac giving the final thrusts as he groaned again. Applejack moaned as she felt the flare twitch and turn within her foal hole, She looked briefly panicked to her brother that has a pained face

"Wait no! Ya promised! Ahh!"

"Sorry sis *grunt* but you feel too good, Ugnn!" He thrust for a final time as it pushed the cervix back, shortly after, it shoot pearly white yet thick and viscous cum against it. Your projections were dispelled as you were shaken by the sudden impact that your bubble against the ringed sphincter.

The cervix shakes and dilates, opening as the walls constrict and turn, shaking as well. "Ahhh!" You heard the Apple Pony moans loudly, orgasming as well.

Seeing the incestous deed being done, you opted to follow the swarm of stallion gametes toward the gigantic gateway to her applemaker, you flew up and gone to the quivering cervix that was slowly opening to let more of the reproductive goo inside, before going in, You looked back seeing the looming, throbbing cock still spewing more of it.

Wow... he was really backed up

You shrugged and went inside of Applejack's compromised womb.

"Ahh!" Applejack moans and pants as she orgasmed, she felt her brother's warm seed invading her nethers. She panted as she looked back to her brother and frowned.

"Ya came in me." She stated with a disappointed glare. Big Mac merely sighed in contentment, no looking fazed of his sister's glare. "What we're gonna do if Ah get pregnant? What Ah gonna say to mah friend when they ask?"

Big Mac's eyes shut open and looked down to his sister's burning glare, he offered an sheppish smile "Uh..." Since Applejack was the embodiment of the Element of Honestly, she cannot lie and if she do, it gonna be a very unconvincing lie, she can't physically do it.

Applejack sighed and smiled "Yer know? Ah can't be mad forever, If Ah get pregnant, yer better take responsibility for it and hope it get born healthy." She sighed "Here Ah hoped to avoid inbreeding."
