I Wasn't Going To Waste That Opportunity

I know my sister has sex toys because i found one in our bathroom when she forgot to take it after her bath,not sure who got it for her with her being only 15,our to cousin's hang out at home and yesterday i came home around midday went to my room and could hear them in her bedroom,I opened the door to find them 3 naked and having sex,my sister spots me watching and tells them they looked to see what i was going to do thinking i might kick off,I could see all off her,I've never thought about her in that way before but that moment was different i couldn't get my clothes off fast enough,our 2 cousin's watching i was on her bed looking her in her eyes pushing every inch into her c**t,her bed was rocking her c**t was being stretched i showed them little pricks how to fuck this bitch, once i filled her c**t with cum i let them have a go with condoms, I watched them fuck her to her c**t never got a rest once they both had her i was straight back in fucking her c**t sore, don't think she will be in a hurry for round two just yet.
