I (f19) jerk my boyfriend (21m) off to younger girls (age play prompt)

An age playing prompt me and my boyfriend use to get in the mood, really satisfying.

Me and my girlfriend have been exploring ageplay recently and this has been our favourite prompt to use to get us in the mood, we are both 24 years old and are consenting partners, all characters in this prompt are completely fictional and above the age of 18, role playing as younger persons.

I met Tom in my first year of college, we were both freshman, though he had taken a gap year working before starting college. I was around 17 nearly 18, he was 18. Our dorms weren’t split by gender so we ended up actually being on the same level. He was quite dorky in a cute way when we met, we hung out a lot but as a group for a few weeks, gradually falling for each other as we spent more and more time. After about a month we were pretty much obsessed with one another but had yet to really do anything, I was quite hesitant an nervous though he never pressured me or made me feel uncomfortable. Flash forward, I decided after about 2 months together I was going to get it over with and do it with him. It wasn’t hard to convince him with a blowjob and we sort of went from there. We both became quite curious about different kinks and went through a sort of experimental phase. He seemed really hesitant to tell me one, but after a night of alcohol and weed (we were both pretty big potheads) he opened up and explained he wanted to try age play but was super embarrassed. I didn’t know where to start too tbh, but I was relieved as it was something I had been curious about myself. we sort of discussed it on the walk back to my dorm (i did not have a roommate as I fortunately had a single room all to myself) and pretty soon i was teasing him calling him a perv, saying he liked kids etc. We eventually got to kissing and I put on a voice, saying something dumb like “wow i’m only 13 and you’ve snuck out to see me” he instantly got harder than I could ever remember. He came pretty fast and it was the hottest thing ever, I felt so naughty pretending to be my younger self. After weeks of sex exploring numbers and scenarios we were sitting on the couch one day, scrolling through my gallery, I was showing him pictures from my childhood phone which we found in a box, at first it was innocent cute photos of myself and friends at the time, then i accidentally scrolled through a series of nudes i took when I was about 14 (i discovered the internet and omegle as a tween and was clinically online with thing way out of my age bracket), Anywasy, I already had my hand on his lap and instantly felt him get rock hard, I sort of got quite excited by this and immediately started to reach for his dick, I stroked him while I scrolled and zoomed through the pictures putting on my ageplay voice “i’m only 13 and you’re jerking off to me” my boyfriend came so hard and it was just the hottest thing ever, we were both thrilled by it. since then all of last week i have been going through my older nudes jerking him off or then fucking while I regress and play as a young teen slut, just yesterday I found my old instagram group chat with my friends where we (on occasion) shared nudes to compare in i think the 7th grade. I think i had just turned 14, and my friends were a similar age. I pretty excitedly have been teasing my boyfriend while we fuck and I give him head as he talks about my friends and we look their old nudes. It is so hot to see him get so worked up over young girls and it makes me feel amazing when we have sex as I just repeatedly tell him how bad he is for having sex with little 12-15 year old girls.

part of me feels guilty for how wrong it is, but our sex life has never been better and we’re both consenting adults in our state.
