I was asked to leave my cousin at her med school. As we were flying, we covered ourselves with a blanket because of cooler environment inside the plane. Before I knew it, my hands touched her hands under the blanket. We both got horny as I could see from her looks. I hissed to her to unzip her pants and told her I will do the same. We were pretending to sleep as the lights were dimmed, but my hands were groping her pussy and her hands were all over my erection. We kept playing and masturbating each other for an hour or so. But, we could not kiss in front of everybody.
Once we reached our destination, we went into a hotel room.
I masturbated her while sucking her nipples. Then we were locked in a long kiss. Then she started stroking me and sucking my nipple too. We both had the best orgasms ever just through masturbation. She told me that there is nothing wrong with playing with each other and have pure fun so long as we do not do any intercourse. After dinner, we went into a prolonged masturbation session again that lasted several hours with kissing and sucking each other all over our bodies. For both, this was our first total pleasure. Now that she is married and me too, we still meet and go through masturbation sessions because it gets boring in marriage after a while.
