Adorable girlfriend with natural breasts gets exhausted during sex

My girlfriend is the sweetest thing, with her innocent face and those adorable natural breasts. I'm so lucky to have her, and I know she's the one for me. We're young and in love, and we're not shy about showing it. Whether we're at my place or hers, we always make time for a good session. The other day, I was working from home when I heard her coming down the stairs in her cute little skirt. I couldn't resist her, and we started going at it right there on the couch. I was pounding away, hitting those tits and driving her wild. I could see her in her glasses, looking at me, her breath getting heavier and heavier until she finally gave in and came all over me. What a hot office sex we had!.
