At 23 I hooked up with an 18yo college freshman. She hadn't been with a guy my size yet and got visibly nervous. Meanwhile my dumb ass hadn't planned ahead so I had no condoms, and she only had standard sized which were difficult and painful to put on. Between the discomfort and her apprehension there was just no way to get in. Fortunately, her mouth was big enough. Her tits were adorable puffy bite-size treats so we each spent most of the night with our mouths full.
