My sister, Ena, loves to drink semen. She used to give me blowjobs in secret from my parents and happily swallow the hot semen. When I entered university and moved to Tokyo to live alone, Ena would come over to my house from time to time... "Hey, brother! Let me drink your semen!!" Ena is definitely a vampire... no, a semen-sucking demon!! She takes off my pants with a smile on her face and lovingly chomps on my dick! She has an innocent face, but she's a super naughty little devil! However, when she sucks on my balls and starts sucking me, her seductive slut side awakens!! When I went to the bathroom to pee, she suddenly came in and licked my piss-covered dick. She quickly gulped it down my throat! When I returned to the living room, she said, "Give me another one!!" I showed her my small dick, saying that it wouldn't get hard anymore, and she started masturbating, saying, "Look at my pussy and get better!" In an instant, I lure the big dick back into my vagina! Brother and sister sex in cowgirl position while pushing my hips against her! "Let me drink more! Let me drink your thick and delicious semen!" A mischievous Kokoro sprouted in me and I ejaculated inside her! "Why are you cumming inside me?! I can't drink your semen! Do it again!" I struggle to make her erect again with a forceful blowjob that sucks up the remaining juice! I swallow another load of cum in my mouth and am very satisfied! While I was in the bath, Ena suddenly bursts in naked! "Hey! You have a girlfriend even though you have me?!" Ugh! I was found out. "I thought it was just my semen..." There? ? ? Her face was sulky and puffy. Eh, are you jealous? "It's not like that! Give me your semen quickly!" In the end, I was made to ejaculate twice while sweating in the bath. After that, we had another intense sex in the middle of the night! How much semen do I have to drink before morning comes? A bittersweet story of incest between me and my sister.
