Stop her and do other stuff

From Create Your Own Story

You hold her head. She looks up, insulted, though kisses you when you move your head towards her. You lay your hand on her exposed breast and take off the rest of the dress. It was quite some work, though with her help you managed. She took off your shirt and pants and together you lay down in the soft fungi field.
You keep her close to you and continue kissing her while you press your penis against her belly and massage her breasts. She crawls on top of you and inserts your slippery penis inside her vagina. It's tight and warm. You push against her force and see her convulse of joy.

Together you come. She moans quietly while you try to hide your pleasure by coughing.
When both of you are calmed down you ask her her name.
"I'm Marisa Kirisame" she whispers in your ear. "I'm an ordinary magician."
"To me a magician can't really be ordinary" you answer.
She smiles and kisses you, but stops abruptly. Just a couple of meters away from you is a girl dressed in red staring at both of you. "REIMU" Marisa cries out while she tries to cover herself. Reimu runs away and Marisa follows her while getting dressed. "Wait" you yell while you stretch your arm towards her.

You wake up with your arm stretched to the ceiling.
Maybe you'll see her in another dream.
