It reminds me of a similar situation where my aunt came into my room unexpectedly to look for something and noticed the lump under the sheet near my penis, which was normal because before she arrived I was masturbating. She pointed it out to me and before I could say anything she lifted the sheet to look at my hard cock then she said to me "I'm going to finish what you started" and then she took my cock and jerked me off until I cum. I keep this memory because it was the first hand that made me cum other than my own
Building these kinds of memories and fulfilling as many of your fantasies, taking the opportunity to try something new. If you're only a little interested, do it, explore your sexuality, you'll only get this chance once, as long as you're safe and you're not hurting anyone, do it!! I'm an almost 70 year old woman who has made many many beautiful memories and you all the regrets that some have. I didn't mean to be so long with this. I love your story 🔥
