What i do is describe smaller details. Small details can be Hawt! ^_^! ~ So like describing
**You feel Nami's inside grip you tight, the perfect slit for your shape! Her moans are husky and desperate for more. Her eyes staring at you with a deep desire, The girl wants you, not only for your dick... but for who you are, She craves your manhood**
Things like that, small gestures with how your hips are posed or just things about surroundings. Like the soft fabric of the couch or the light from the window makeing her skin glinze ~ You know xD Things like this makes things alot more real in the moment.
