Sleepover with my boyfriend

My parents are strict, but his are even worse. we’ve been together for almost a year now (on March 31st) and we’re wanting to spend the night. We need a good excuse. On Christmas <a href="https://play.google.com/store/apps/details?id=com.glow.android.eve">Eve</a> I stayed the night at his house, but only because we got snowed in and he had to sleep in his parents room😂 send help. Any tips on how to get there trust or good excuses.
