I was staying with my sister Rachel and her husband Matthew at their caravan for a few days. Their bed was at one end of the caravan and I had been sleeping on one of the sofas at the other end. Changing was no problem, none of us were bothered or embarrassed about undressing in front of each other.
I was slightly jealous though, they had each other to cuddle into, and despite being slightly shorter than the average man, Matthew was very nice to look at, with a proper manly hairy chest and nicely shaped muscles, nothing over the top. I had not yet looked at his genitals properly though. I had tried to catch glimpses when I thought they wouldn't notice, but was unsure if I was allowed to look openly, so I chose not to, despite the temptation.
This particular afternoon, Rachel was getting ready to go for a walk. I had no interest in walking that day, and neither did Matthew, so we were staying behind at the caravan. Having woken that morning at my usual time of 4:30, despite not having work, I was now feeling a bit tired. I asked if they minded if I lay down on their bed. They said that was fine, so I took off my shoes and lay on the bed facing the wall, with my back to them. I didn't actually fall properly asleep, I just dozed.
I heard Rachel say goodbye and leave. A few minutes later Matthew climbed on the bed and cuddled into my back, wrapping an arm around my belly. It felt so nice to be cuddled, and to feel his body heat through my t-shirt. I hummed contentedly and we dozed together for a bit.
After a while, I wasn't sure how long we had dozed for, I felt his hand slide from my belly up to my breast and gently caress me. Slightly surprised, I hummed with pleasure and moved my top arm to give him better access. He responded by sliding his hand inside my t-shirt and continuing to caress my braless breasts. I arched my back to push my breast further into his hand. He continued to stroke my breasts, brushing over my nipples and getting me all excited. I reached my hand tentatively back and gently stroked his thigh. When he did not object, I moved my hand slowly upwards searching for his bulge. Upon finding it, I stroked my hand gingerly over the bulge in his trousers, slowly up and down.
As he played with my breasts, turning me on more, I grew more confident in my stroking of his bulge. Soon, rather than just stroking whichever part I happened to touch, I purposefully curled my fingers and found the shape of his shaft, trying to wrap my hand around it as best as I could through his trousers and stroking up and down his length.
I was just beginning to think, "I wish he would stroke me between my legs," when we heard the awning zip go and Rachel returned. We quickly let go of each other and got up.
The next few hours were spent pleasantly together watching the TV and chatting. At half 5, Rachel headed out to play bingo with her friends, while Matthew started preparing a meal for him and me. We watched more TV while we ate, he's an amazing cook, then we talked for a while. I decided to wash the dishes for him. He watched and chatted while I did, then as I was washing the last dish, he came up behind me, as though trying to get past in the tight space, but instead stopped right behind me and put his arms around my waist. I put the last dish on the drainer, pulled the plug out and put my wet hands on top of his.
