                  When I woke up this morning I didn’t know what to expect...I surely didn’t predict hearing a high pitched man talk about 30 minutes of dry thrusting.

                                  Mark sounds like smeagle like kinda expect him to say "my precious " while maliciously looking at Ethan

                                            When they are talking about Abigail, ethan sounded exactly like moaning myrtle. It hit me at 1 in the morning when I woke up to get water

                                                  This video of white noise and smooth jazz was nice, except for the occasional laughter that could be heard in the distance. 3 stars.

                                                    Hearing about Mark's first time was so cringe and awkward to listen to.

                                                        Mark with helium at first sounded like a tiny European but then turned to a western outlaw
