"Big Sis... I-I'm pregnant..." I pant, holding Azraelith's hands. Her tail writhes, messing up my insides completely. Now I understand how strange it can feel to have a "tail" inside your body.
Because of its tapered shape and very fine tip, it enters the womb, but when it opens, blooming like a flower and anchoring itself to the walls, it's a very painful process, though it's very pleasurable too.
"Really, Pandora? You're telling me this now? Couldn't you have waited a bit longer?" Azraelith seems dissatisfied, since this means we have to stop and leave here. After all, I can't let this baby grow too much. I've even already planned to use time magic to stop its growth if the fight takes too long to start.
"Y-Yes... I don't control my pregnancy, you know? It was my body that wanted your little seeds just now," I murmur, exhausted. My big sister really fucks hard when she lets her instincts take over, even though my body was already sexually tired because of Grimm.
