I'd have sex with her.
I'd admire her smooth silky skin and her lush purple hair.
I'd slowly remove her silky panties and slip my hand down until she could not take it anymore, I would slowly remove every item of clothing, caressing and kissing her body at the same time.
Then finally I would get into the missionary position and make sweet love to her. Whilst looking deeply into her eyes. Under the bed sheets.
There would be some sweet romantic Jazz playing in the background.
We would be in a dimly lit room with only a candle at the foot of the bed as a light source.
