I am going to participate with a group naked bike ride with my friends on a warm summer night. We are meeting at my friend Jenny's apartment. She is a tall, fit, woman about 28 years old. She has long, toned legs, medium breasts, and a round, tight ass. Her hair is long, brown, and curly and she has distinctive italian-american features. She is goofy, silly, and very stylish. When I get to her apartment, she tells me that the rest of our friends have gone on ahead and we need to catch up. Since we're running late, we both decide to undress at her apartment and leave our clothes there during the ride. We quickly get naked, but then realize how awkward it is that the two of us are naked, alone, in her apartment. We are both secretly impressed by each other's  bodies. I get so excited by the sight of her naked, that I get an involuntary erection, which I can't hide since I'm naked. Jenny is shocked and impressed by how big my dick is getting. The conversation gets tense, as our animal instincts kick in more and more. Jenny half-heartedly suggest that maybe I go into the bathroom and "take care of that" before we leave, but as I walk past her to get to the bathroom she surprises us both by dropping to her knees and swallowing me all the way down to the base...
