That's quite normal for the ladies and females and even for the guys...both will sleep completely naked immediately after they cum and for the guys after they shoot out their load of sperms...both flatten and tired out by the furious action and explosion at their bottoms.. trying to make each other enjoy sex ...and yes, it's quite common, just like sis Treesa, many ladies would usually go to bed dressed in only a tee and panties...feels comfortable as she says but it makes me hard when i see that
When my wife and I were newlyweds, we tried to sleep naked, but we didn't get much sleep. Just thinking about her lying there, naked, made me touch her, which led to sex and no sleep. We decided we had to wear something to bed or we would die of sleep deprivation.
