She chooses Chiron

"Mmmm Marna! Please wait a moment, I need to think," Venus gasped as the other woman inserted a finger into her already abused pussy. Marna lifted her head from Venus's nipple and gave her a weak smile.

"I'm sorry I just really wanted you. When I first saw you and tended to you... Venus you are the first and only woman I have ever wanted. I love Chiron but I want to love you too."

Venus closed her eyes in thought for a moment.

"So Centaur are polygamous? One can have multiple wives? Do they take lovers when they already have wives?"

Marna nodded. "It isn't uncommon though to my knowledge Chiron is only with me sexually. The wives sometimes take lovers too, but that is rare."

"So if I give myself to you and Chiron, I could still see Janus from time to time?"

Marna bit her lower lip for a moment in thought.

"If you choose Chiron over Janus there may be some hurt feelings. I don't know if I can help to smooth things over but I would try."

"Ok."

"What," Asked Marna blinking in surprise.

"I am willing to be Chiron's mare and love both you and him, but Janus was my first. I would like to try with him at least one more time."

Marna blushed deep crimson and nodded slowly.

"I think Chiron would allow that. I've been able to get him to agree to some wild things in the past, but seducing Janus again will be up to you."

"Thank you Marna," Venus said as took the woman into her arms and kissed her deeply, letting her tongue tease Marna's lips a moment before pushing past and in to tickle her tongue.

Marna was moaning and pressed against Venus when the door to cabin Marna and Chiron lived in opened. Whoever was entering could easily see the two women kissing in the bath and Marna's hand teasing Venus's pussy under the water.
