To me there's nothing better than when a guy pulls off his pants and is standing there in his underwear, partially or fully hard, and I'm aware of his endowment for the first time. I know it's about to spring out but I haven't seen it yet. The anticipation is incredible during those few seconds...I'm wondering if he's cut or not, whether he's got a nice mushroom head, what the texture of his skin will feel like against my tongue...of course, making out with someone fully clothed and feeling their dick strain against their jeans is a pretty incredible feeling as well.
