There's nothing like having a quick jerk off session right before bed. Releasing every last drop of cum you've built up throughout the day. Your balls are aching to explode, but you're so tired- why should you have to get up out of bed to clean yourself off? It's too late for that, you want your rest. Stroke it and tug on those balls while your legs end up over your head- open wide, swallow your cum as you orgasm. Nighty night.
