Having fun with my sister

I am a 15 year old and my oldest sister is married and gone…2 years ago when i was 13 on my birthday, pretty boring day…Btw im skinny but my dick is 5 inches .On my birthday i wake up an my room is so hot it was like 90 so i got up and went to my sisters room which is my oldest sister and i went to sleep…she is 25 between my sis’s room i would usual put my hand around her and put my leg over her…Note that i had no intentions of any sexual activities with her. So i went to her and slept and held her close…she jerked and turned toward me…i saw her boobs, god my dick grew fast but i moved a little bit away so i would not poke her…she moved toward me and my dick obviously poked her but she smothered me with her boobs…i did not care so i put my hand around…when i did her shirt on the other side was up to her bra strap…so i was just very happy…so i started caressing her on the back about 30mins later i got up and masturbated and went on with my day…The next day i went back to her room purposely and set my hand on her stomach(with her shirt on)…5 minutes later i lifted her shirt up all the way to her bra…i got such a hard on and she turned away but did not remove my hand from her covered boobs…now i was looking at her back but i thought she wanted her bra removed so i did and threw it some where in the room..and was caressing those lushes boobs…I tugged her towards me and she turned around.. So i was looking at her boobs and stated fondling her nipples…then just started ferociously licking them…then suddenly came a rush of milk and she let a grunt out happily i licked all the milk away…then i was done with boobs tugged her away so she was facing opposite of me..so i went down to her pants and tugged them a little down…and luckily no panties..i felt he pussy then just rigorously fingered her for 10 minutes..she then got up and would not let me touch her…about 1 year later i i went to her room to see if i could do it again..and i asked her if i could sleep with her and she said yes…i jumped in the bed and slid her pants off and she giggled…she said be careful and i figured in my language she said don’t cum in me.. She was facing opposite of me and it was bigger than ever.i stuck t in her and thrust back and forth she held her moans 10 minutes of thrusting i quit…that was the last time i spent quality time with her…now she is married but i know when she come to visit im gonna have me some fun…i live in USA so add my hotmail and live accounts and we can talk about the REAL life story and maybe have some internet sex, il send u pics of some stuff or ……..i have msn messenger so ill be waiting…
