1st Time Being Pegged

My girlfriend has been asking for a few months to peg me, anal play has never been my thing so I always refused and even at 1st assumed she was joking. Eventually I realized she was serious so I started asking why she wants to so bad considering she wouldn’t feel anything anyways. She admitted she thought it would be so sexy to have that much control of me in bed. My girlfriend is very much the dominant one in the bedroom, she usually always wants to be on top and even in doggy she throws her ass back while I just hold on. I think it’s very hot to have a girlfriend that aggressive, she likes to talk a lot of trash in bed even to the point of telling me I have a small dick and telling me her exes fucked her better. She has told me in the past to not worry too much about what she says during sex because it’s just another way she likes to be dominant in bed and she knows im into it so it always works for us. So after hearing her out for a few months I decided to tell her as a birthday present she can peg me. She was so excited and even went and bought a 6 inch strap on. The 2 weeks leading up my girlfriend started playing with my hole a bit to slowly get it ready for the 6 inches. She started fingering me during blowjobs or she’d give me a handjob while she did it, at times having 3 fingers in me once. It wasn’t bad at all and I was getting off to it but I knew it was nothing compared to a 6 inch penis. On her birthday she was walking around proudly with her strap on telling me she had a bigger dick then me multiple times. She was right, her strapon had a about 2 inches on me which honestly scared me more that it was gonna hurt. But the time finally came and I got in position on all 4’s on the bed. My girlfriend gave me a slap on my ass and then started lathering up my hole and her strapon with lube. I was surprised but happy she started off slow, going all the way in but stopping so my hole could stretch and get used to the pressure. After she felt comfortable that I was ready she started going in and out very quickly. I’ve never felt more vulnerable at that moment, in a complete role reversal with my face my pushed into a pillow and my butt being arched in the chair while my girlfriends waste slapped into my butt, but I will say I was definitely enjoying it. My girlfriend was talking her normal trash and telling me this how she felt when her ex fucked her in the ass which put me over the edge and I shot my load all over the bed and let out a loud “oh fuck”. My girlfriend wasn’t done and flipped me in a bunch of different positions over the next hour. I was totally stretched out and exhausted when my girlfriend said it was her turn. I put my dick into her and it was literally dripping wet and didn’t take long at all too get her to finish. She was so happy after ward and thanked me a bunch. I admitted I really liked it and now we have done it twice more this week. We have talked about getting 2 guys to come in and fuck us both at the same time which I’m again nervous about considering I never even thought about being with another man before this week but I’m definitely thing about it (:
