I enjoy pushing my boytoy to the limit. The other night I spent all evening teasing him and making his balls fuller and fuller, using different parts of his body to make myself cum, but not letting him cum, or even touch his aching cock.
I used him over and over again, until it was time to get ready to go out. Just before we went out for a drink with friends, I tied a piece of string around his balls, pulled it nice and tight - I like it when it really cuts into the skin - and then made him cut a hole in his pocket and thread it through.
It was a busy restaurant, I sat next to him all night, at a table with 5 of our friends, and pulled on the string from time to time, it was such fun..for me. I made him order all the food and drinks, coming up with reason after reason for him to call the waiter over, and pulling the string harder and harder as he tried to talk. He was a stuttering, wincing mess. He got a lots of funny looks from the waiting staff, our friends, and the other diners, some of them giggling and pointing by the end of the evening. He kept glancing at me with pleading eyes. I just laughed and pulled harder.
At one point I unzipped him under the table and roughly grabbed his throbbing cock. He gasped as I yanked the foreskin back. I looked at him innocently. "Is everything ok?" He couldn't reply, only stare at me, wide eyed and panting, as I wanked him. I took him right to the edge, and then abruptly stopped. He begged me with his eyes. I laughed.
Eventually I took him to the toilets and let him fuck me. As I came, I yanked on the string, stretching his balls and tearing the skin as he tried to stay quiet - still not allowed to cum. He was a mess when we emerged from the toilets; breathless and dazed. I love seeing him so desperate.
