Although I was in my early teens, puberty had blessed me with ample breasts and beautiful puffy pink nipples. Oh I loved rubbing and pinching them! I ...reed my teenage tits from their wired prison and had them hanging over my bra then slipped my knickers down to my ankles, this made me feel very naughty indeed. As I was rubbing and teasing myself I was thinking of all the things that turn me on when suddenly a thought popped into my head...I had "accidentally" walked in on my step dad stroking. He took my ankles and lifted my legs up onto his shoulders, then moved his hands and put them on the back of my knees and bent my legs down towards my shoulders so I was pinned down with my ass in the air. He moved his face down and licked my balls briefly before rimming my ass with his big strong tongue. This was the first time I had this done to me and it was amazing, I wish he could have done that forever it got me so close to cumming without having my cock touched!I think he knew he would. This increased the tingling from my cunt, knowing I risked punishment for playing with myself, I resisted all temptation.Finally at 1 pm I dressed as ordered and set off to our meet. I was really conscious of the fact I had only two items of clothing covering my body. I am sure I had my arse stroked deliberately as I was standing on the tube; during the journey. I arrived at 2.30 pm and had to will myself not to walk directly to the Memorial. So I had a coffee at the Cafeteria in the. Suddenly the gondola bumps over another tower and swings wildly, causing you to lose your balance and plunge into me. Once in motion you can’t hold back and you begin to drive yourself deeper and harder into my wet, willing pussy. Your hands grip my hips harder, pulling me onto your cock, your cockhead rubbing all the right spots. Pressure begins building in my core and all I want is more, harder, faster. Fuck me. Soon a powerful orgasm shudders through me and I feel my pussy clenching around.
