Yes to it being real, as in, I'm not making it up. Not that you can space them out that much anyway, but some were after a very short refractory period as well. I thought that the
Denise scenes were all cut short/edged like at the initial couple of apartments, but she said later that she got six creampies, which is why she needs to take the extra precaution of getting a morning-after pill.
To the other part though, on the
possibility of it... yeah, you and me both! I remember when I was 18 and celebrating moving into my new student house with my girlfriend. We had sex six times in one day, in every room of the house, and I genuinely had to fake an orgasm the sixth time
