Our boy comes into our bedroom at night, he snuggles next to me. He always has a really hard erection so i pretend to be not awake and let his hands explore my body, even sucks my nipples remembering when there was milk. Naturally his erection pushes against my vaginal opening so i open my legs and let him slip inside of me. He cums quite quickly, but keeps his erection and he keeps fucking me, i wrap my arms around my husband and our boy cums inside me again. Then we all sslp to morning - nice and relaxed and natural.
