I decided to go to my girlfriend's house where she lives with her sister. The older sister who greeted me liked me and started playing pranks everywhere! She sneaked a breast-squeezing blowjob while she wasn't looking, a periscope titjob in a mixed bath, and an all-you-can-eat breast-feeding handjob... The best part was raw sex where my dick was rubbed directly on her vagina! I couldn't hold back and came inside her, and even though she found out, I couldn't stop because her pussy was too good! Her older sister seduced me with her big tits and allowed me to come inside her!
