The gap between a pair of juicy thighs is there for a reason. Have you ever slid your cock inside it? Once you feel how good that soft skin feels against your dick, you'll want to keep it in there forever. As you're fucking a babe's thighs, feeling her pussy sliding on top of your cock, she'll press your dick inside her legs. Just hard enough to let you know they're begging you to stay there. Once you're done, your cum will run down her thighs, and only then will you know you are done, but you'll be desperate to do it again.
