Gf testing

Long time ago (I was about 21 and she was 17 then) I wanted to 'test' my gf - to know if she would be faithful.

In the summer we went trekking - me and her, and my friend Frank. It was in the mountains and we carried only one tent. Big enough for 3 but otherwise pretty tight quarters. I knew that my friend liked my gf too, so I simply asked him to test her for me - and see what she would allow him to do with her.

We went to sleep and I pretended to fall asleep fast. I slept on one side, my gf in the center, and my friend on the other side. He started to ** her through her sleeping bag and when she turned away from him he grabbed her bottom and started rubbing her. My gf tried to wake me up and she whispered to me that 'Frank touches me'. But I pretended to be sound asleep and I did not react.

Next night we did the same thing and this time she did not try to wake me up. And the following night she let Frank unzip her sleeping bad and ** her. Frank told me what progress he had made and I could hear him making good progress every night. He got as far as unloading on my gf's naked belly as she stroked him and he stroked her.

Next day when we stopped to buy food in a small village my gf went to call home and Frank asked me how much farther he should go. He did not want to lose my friendship but it was clear my gf was accepting his advances and he enjoyed her body. I told Frank to go as far as my gf allowed him. I asked him to take her clothes off too to let me watch her secretly.

I thought I lost my gf to Frank.

Frank made great progress the following week too. I could now watch my gf getting properly ruined by Frank. She gave him oral and when I rolled over to face the wall of the tent she gave him her bottom too. Frank was silent, but my gf was breathing heavily any time Frank did her good. Especially whenever he went into her smaller hole.

When our trip was almost over and we had only one more night to go, I thanked Frank, and I asked him to not let my gf out of the tent on the last night, no matter what. So he knew I was up to something.

The night came and I pretended sleep. My gf turned to Frank and they started to play their game, Frank removed her ** and slid her sleeping bad off her. I turned round and watched my gf's back and listened to her breathing. I got very hard and when I knew that my gf was closing on to her climax, I silently unzipped my sleeping bag.

My gf's naked back was right in front of me and from how she moved I knew Frank's thing was now inside her. Without touching her I waited and when Frank took a short break to put a rubber on I suddenly I entered her from behind. No rubber no nothing. One deep stroke and I was there. All the way.

My gf froze but uttered no word. I pushed into her deep and pulled out, then immediately pushed deep again. Now I grabbed her hip and started thrusting into her. I was half way to having my revenge complete when I noticed Frank tried to enter my gf from the other side - but now that he found me there, he stopped.

I grabbed my gf's long hair and pushed her head low, till her face was close to Frank's ** and there I let her hair go and I placed my hand on her mouth and opened it. I pushed her hard from behind and I pushed her open mouth towards Frank's thing.

Frank seemed surprised but he kept his cool. My gf was trying to get free of me but I made her take Frank into her mouth. She had no choice and started licking him. And when she did that, I pulled out and turned her round and pulled her head to my **. She understood what I wanted from her and started giving me oral. I gestured to Frank and he took her from behind.

I do not know what my gf expected, but that night we went on try all possible combinations of ** love. Including dvp, **, and dp. Not everything worked, but I made ** sure it was difficult for her to walk straight in the morning.

We walked the last leg of the trail and we went each our own way. But, miraculously, my gf did not report us, nor broke up with me. We talked the whole adventure over and she agreed she wanted Frank as much as she wanted me. And our surprise sharing her was not what she planned for, but once it started she kind of resigned herself to the idea that it was her own fault. And a better thing than having a secret affair with Frank.

I told her I was going to dump her, but then I found the view of her being copulated by Frank so exciting that I wanted to see if she could have us both at the same time too.

Much later Frank moved to another state and we never found a trustful candidate to replace him. My gf is now my wife and we live a stately life here. We have two kids. They may be mine or Frank's. We do not know because we made them while playing our favourite 'hole overflow' game with my wife.

She sings in a church choir. She says the pastor is very hot, but we lack guts to ask him to go on a mountain trek with us.
