During my first year undergrad I met Sophia (21F, not real name) at the church. She was a petite blond with a nice pair of grapefruit-sized tits. She was a college student so we studied together a lot and eventually started dating.
There was a lot of sexual tension from the start, but she had been taught that sex is evil and that her pussy should belong to her future husband only. She even had one of those *purity rings* and made me promise not to touch her privates. I was her first boyfriend.
One day we were home alone and she was feeling stressed for the upcoming exams, so I gave her a massage. She was lying face down and I started rubbing her back, then I could not resist pulling up her shirt and then the bra. I started rubbing her tits slowly then pinched her nipples for a while until I garbed the whole pair (this was my first time too). They were firm and so big I could barely hold them with my hands. Sophia was so excited that she sat on my dick with her clothes on and started grinding it with her hip movements while I licked her pink beautiful tits. Alas, she suddenly snapped out the trance and ashamed herself. She started crying and I had to apologise.
