The crimson princess

Pov Dia,

We are back for another night. Since this morning, I have been very eager to test this spell, but I would rather do it in the evening than in the middle of the day otherwise I would not have been productive during the day. I didn't even want to do it.

That night, I was going to do it with Sera and Rimuru at the same time. We could alternate every two days, but the problem is that we are so united that sometimes we prefer to sleep all 3 together.

I was at this moment completely naked to try the futanari spell. When I turned it on, I felt a weight in my crotch and when I lowered my eyes I could see a cock. It's extremely strange to have this in her crotch and I could see that her size was a little smaller than Rimuru's.

Rimuru:" The size of the cock varies according to the size of the partner. I am a few inches taller than you, so I have a bigger cock than yours. I obviously adjust the spell so that there is no size too large so a person measuring 2m will not have 30cm or 40. "

Sera:" I don't even know if I should be afraid that you have guessed them from Dia-chan or that Dia-chan could make the difference in size which shouldn't be three big. "

Dia:" Don't think or you'll have a headache, enjoy this moment and test the spell too."

Sera obeys, and a cock appeared on her crotch. It was bigger than mine and Rimuru's of course because after all it is bigger than the three of us.

Dia:" I will start with you Rimuru but I would also take care of you Sera even if it is only with my hand."

There was no need to lubricate before starting because Rimuru is a slime and the inside looks like slime it was very strange the feeling I had on my fingers when I penetrated it with these."

I brought my cock closer to the entrance of Rimuru's pussy before inserting it and this sensation is indefinable. I have a feeling that it is laid in the water without being too liquid and that it is massaged from the inside of Rimuru.
