I live with two very repressed room-mates in an apartment. I've been somewhat frustrated with them lately, we've talked about masturbation before, and they feel that it is wrong, even though they do it anyway. I'm planning on moving out (for some other reasons) and in that spirit I had a fun, freeing experience the other day.
First I locked the door, and opened the window so I could hear a car door shut in case one of them returned unexpectedly. Then I stripped completely naked and set my clothes in a pile, and got up on the edge of the wooden kitchen table, placing my feet on a chair. I was already hard at this point in anticipation. I slowly began to stroke myself with one hand, and fingered my anus externally from the front, while leaning back for a bit. Then I got a little more daring and got up on the table fully, still stroking with one hand while sitting cross-legged. I placed my other hand underneath myself and ground onto it, while my focus and pleasurable feelings increased. Finally, I placed one foot on the chair, one leg up on the table, and rubbed my anal area on the edge of the table directly, still stroking my wet, erect penis. I edged for a while in this position, and finally ejaculated out onto the kitchen floor. (I thoroughly washed the table and cleaned up when I was done.)
I will not be repressed!
