With lube

You grab a bottle of lubricant that Lucy and Josh had kindly left on your bedside table, and smear a dollop onto your cock. Then, you press your cock against Lucy's pussy. Your cock slides in easily.

Your thrusts increase in speed and intensity as Lucy's pussy clenches around your cock. You lean forwards, using one hand to balance yourself as the other one fondles one of her breasts. Lucy stares up at you, her face contorted with lust, as you continue to fuck her.

Finally, you pull out of Lucy's pussy. You stroke your cock, which is still wet from the lube, and her juices, until you cum on her.
