While traveling with my son and DIL, we experienced some car trouble and would have to stay overnight. We tried a couple of hotels and we could only find one room with double beds. So, we took it. We all settled down and went to bed my wife and I in one and them in the other.

After about 30 minutes, I hear them start to whisper and I look over and they are removing clothing, we all had basically shorts and t-shirts on…my wife dead asleep and they think I am too.

After they get clothes off and they are trying to be discreet, they realize the best position is my so behind her on their sides. I could hear him fingering her getting her wet and my cock started swelling. Naturally I reached down and stared rubbing it under the sheet.

After some foreplay and he was definitely inside her and I look over and see that they are facing our bed, my son hidden behind her and I see her face and she sees me rubbing under the sheet.

She pulls back the sheet and exposes her breast and head motion like she wanted me to pull back my sheet, which I did. I was now of course fully hard and stroking carefully not wake the wife.

She was just laying there taking my son and watching me stroke. Luckily I finished right before him and there was a washcloth on the nightstand that I came in and put it back on the night stand.

The next morning, we rotated for showers and my DIL said can I use this washcloth for my shower and my wife said yes.

Nothing has was ever said. No, she doesn’t want to fuck me, nor I her. Everyone caught up in the moment…but damn it a fun moment.
